CPR Neonatal Resuscitation 1 — Questions and Answers

Question 1: According to the Neonatal Resuscitation Program (NRP), what is the first step when a newborn is delivered?

Immediately clamp and cut the umbilical cord
Provide warmth, dry and stimulate, position and clear airway if needed, and assess the newborn's condition (Correct answer)
Begin chest compressions
Administer epinephrine

Correct answer: Provide warmth, dry and stimulate, position and clear airway if needed, and assess the newborn's condition

The initial steps of neonatal care are warmth, drying and stimulation, positioning, and assessment of breathing and heart rate.

The NRP initial steps for newborn care at delivery are: (1) Warm and stimulate: place the infant under a radiant warmer, dry vigorously with warm blankets, and use the towel rubbing stimulation to stimulate breathing, (2) Position: position the head in a slightly neutral or extended ('sniffing') position to open the airway, (3) Clear the airway only if necessary (not routine suctioning), (4) Assess: observe breathing and heart rate within 30 seconds. Approximately 90% of newborns transition without intervention. The most important initial interventions are warmth (preventing hypothermia), stimulation, and assessment. Routine suctioning is no longer recommended unless the airway is obviously obstructed.

Question 2: At what heart rate threshold does the NRP recommend initiating positive-pressure ventilation (PPV) in a newborn?

Below 100 beats per minute with labored breathing or apnea (Correct answer)
Below 60 beats per minute
Below 80 beats per minute
Below 120 beats per minute

Correct answer: Below 100 beats per minute with labored breathing or apnea

PPV should be initiated if the newborn has apnea, gasping respirations, or a heart rate below 100 bpm after the initial steps.

According to the NRP, positive-pressure ventilation (PPV) should be initiated within 60 seconds of birth (the 'Golden Minute') if the newborn has: (1) Apnea or gasping respirations, or (2) Heart rate <100 bpm despite initial steps. PPV is the most important intervention in neonatal resuscitation because the primary cause of newborn cardiac arrest is respiratory failure (not primary cardiac failure as in adults). PPV is delivered via face mask (or endotracheal tube/laryngeal mask) using a T-piece resuscitator, self-inflating bag, or flow-inflating bag at a rate of 40-60 breaths per minute with just enough pressure to achieve visible chest rise.

Question 3: What is the recommended initial oxygen concentration for PPV in term (≥37 weeks) newborns during resuscitation?

100% oxygen
21% oxygen (room air) (Correct answer)
40% oxygen
60% oxygen

Correct answer: 21% oxygen (room air)

Current NRP guidelines recommend starting PPV with room air (21% oxygen) for term newborns, titrating upward if oxygen saturation remains low.

The 2015 and 2020 NRP guidelines recommend beginning PPV with 21% oxygen (room air) for term (≥37 weeks) newborns. Evidence shows that starting resuscitation with 100% oxygen is associated with increased oxidative stress and no benefit in term newborns. For preterm infants (<35 weeks), higher initial oxygen (21-30%) may be used. A pulse oximeter on the right hand (preductal) should be used to titrate oxygen to target SpO2 values for the first 10 minutes: 60-65% at 1 min, 65-70% at 2 min, 70-75% at 3 min, 75-80% at 4 min, 80-85% at 5 min, and 85-95% at 10 min. Oxygen should be increased if the newborn's SpO2 remains below target despite adequate ventilation.

Question 4: What is the recommended compression-to-ventilation ratio for neonatal CPR?

30:2
15:2
3:1 (90 compressions and 30 breaths per minute) (Correct answer)
5:1

Correct answer: 3:1 (90 compressions and 30 breaths per minute)

Neonatal CPR uses a 3:1 ratio (3 compressions to 1 breath), giving 90 compressions and 30 ventilations per minute.

Neonatal CPR uses a 3:1 compression-to-ventilation ratio (unlike the 30:2 ratio used for adults and children). This gives 90 chest compressions and 30 ventilations per minute. This higher ventilation-to-compression ratio reflects the fact that neonatal cardiac arrest is almost always due to respiratory failure (hypoxia), making ventilation the priority. The team delivers compressions and ventilations in a coordinated rhythm: 'one-and-two-and-three-and-breathe.' A brief pause for each breath is necessary to ensure effective ventilation. If the newborn has cardiac arrest due to a primary cardiac cause (rare), a 15:2 ratio may be considered, but this is not standard NRP protocol.

Question 5: When should chest compressions be initiated in neonatal resuscitation?

When the heart rate is below 100 bpm
When the heart rate remains below 60 bpm despite 30 seconds of adequate PPV (Correct answer)
Immediately upon birth if the Apgar score is low
When cyanosis is present

Correct answer: When the heart rate remains below 60 bpm despite 30 seconds of adequate PPV

Chest compressions begin when the heart rate is <60 bpm after at least 30 seconds of effective PPV, confirming that ventilation alone is insufficient.

In neonatal resuscitation, chest compressions are initiated when the heart rate remains below 60 bpm despite a minimum of 30 seconds of effective positive-pressure ventilation (confirmed by visible chest rise, bilateral breath sounds, and ideally SpO2 monitoring). Ventilation is always attempted first because the primary cause of neonatal cardiac arrest is respiratory failure. Before starting compressions, ensure ventilation has been effective—if chest rise is not occurring, the MR SOPA corrective steps should be applied (Mask adjustment, Reposition airway, Suction mouth then nose, Open mouth, Pressure increase, Alternative airway). Compressions should begin with intubation performed as quickly as possible for an effective airway.

Question 6: What is the APGAR score and what does it assess in newborns?

It measures blood glucose, pH, and oxygen levels in newborns
It is a 5-category scoring system (Appearance, Pulse, Grimace, Activity, Respiration) scored at 1 and 5 minutes of life (Correct answer)
It predicts long-term neurological outcome with accuracy
It is used to determine when to start or stop neonatal resuscitation

Correct answer: It is a 5-category scoring system (Appearance, Pulse, Grimace, Activity, Respiration) scored at 1 and 5 minutes of life

The APGAR score assesses five components—Appearance (color), Pulse, Grimace, Activity (tone), and Respiration—each scored 0-2 at 1 and 5 minutes.

The APGAR score was developed by Dr. Virginia Apgar in 1952 and assesses 5 signs at 1 minute and 5 minutes of life: A = Appearance (skin color: 0=blue all over, 1=blue extremities, 2=pink all over), P = Pulse (heart rate: 0=absent, 1=<100, 2=≥100), G = Grimace (reflex irritability: 0=no response, 1=grimace, 2=cough/sneeze/cry), A = Activity (muscle tone: 0=limp, 1=some flexion, 2=active), R = Respiration (0=absent, 1=weak/irregular, 2=strong cry). Scores: 7-10=normal, 4-6=moderately depressed, 0-3=severely depressed. The APGAR score is useful for documenting transition and communicating condition, but resuscitation should not wait for the 1-minute score—initiate as needed.

Question 7: In NRP, what is meant by the 'Golden Minute'?

The first minute of life, during which the Apgar score determines treatment
The first 60 seconds after birth in which initial assessment and PPV (if needed) should be completed (Correct answer)
The 1-minute window for umbilical cord clamping
The time from birth to delivery of the first medication

Correct answer: The first 60 seconds after birth in which initial assessment and PPV (if needed) should be completed

The Golden Minute is the first 60 seconds after birth—if PPV is needed, it should begin by the end of this minute.

The 'Golden Minute' concept in neonatal resuscitation means that within the first 60 seconds after birth, the initial steps of resuscitation (warm, dry, stimulate, position, assess) should be completed. If the newborn is not breathing adequately or has a heart rate <100 bpm by the end of this minute, positive-pressure ventilation must be started. Delays in initiating PPV beyond the Golden Minute are associated with worse outcomes. This emphasizes the need for a skilled resuscitation team to be present at deliveries where problems are anticipated, with all equipment prepared before birth. The rapid assessment-intervention cycle is critical because neonatal bradycardia and apnea respond quickly to effective ventilation.

Question 8: What is the preferred technique for neonatal chest compressions according to current NRP guidelines?

Two-finger technique using index and middle fingers
Two-thumb encircling technique with hands encircling the chest (Correct answer)
Heel of one hand on the sternum
Fist compression technique

Correct answer: Two-thumb encircling technique with hands encircling the chest

The two-thumb encircling technique is preferred for neonatal compressions as it generates higher coronary perfusion pressure and is less fatiguing.

The two-thumb encircling technique is the preferred method for neonatal chest compressions: both thumbs are placed side-by-side (or overlapping for very small infants) on the lower third of the sternum (just below the nipple line), while both hands encircle the chest with fingers supporting the back. This technique generates higher peak systolic pressure, better diastolic pressure, and better coronary perfusion pressure compared to the two-finger technique. It is also less fatiguing over time. Compression depth should be approximately one-third of the anteroposterior diameter of the chest. The two-finger technique (index and middle fingers) can be used when the two-thumb technique is not feasible (e.g., during umbilical venous catheter placement).

Question 9: What is the first-line medication for persistent bradycardia in neonatal resuscitation despite effective PPV and compressions?

Atropine 0.02 mg/kg IV
Epinephrine 0.01-0.03 mg/kg IV/IO (1:10,000 solution) (Correct answer)
Sodium bicarbonate 2 mEq/kg IV
Adenosine 0.1 mg/kg IV

Correct answer: Epinephrine 0.01-0.03 mg/kg IV/IO (1:10,000 solution)

Epinephrine 0.01-0.03 mg/kg IV/IO is the first-line medication in neonatal resuscitation when heart rate remains <60 bpm despite effective ventilation and compressions.

Epinephrine is indicated in neonatal resuscitation when the heart rate remains <60 bpm despite at least 30 seconds of effective ventilation (with adequate chest rise) and at least 60 seconds of effective chest compressions. The recommended dose is 0.01-0.03 mg/kg IV/IO of 1:10,000 epinephrine (0.1-0.3 mL/kg). The preferred route is umbilical venous catheter (UVC) for rapid drug delivery. If IV/IO access is not yet available, an endotracheal (ET) dose of 0.05-0.1 mg/kg of 1:10,000 epinephrine can be given, though the ET route is less effective. Epinephrine can be repeated every 3-5 minutes as needed. Volume (normal saline 10 mL/kg) may be given if hypovolemia is suspected.

Question 10: What special resuscitation consideration applies to meconium-stained amniotic fluid when the newborn is born vigorous?

Immediate deep tracheal suctioning regardless of newborn's condition
Routine initial steps without routine tracheal suctioning; only suction the trachea if the newborn is non-vigorous and has airway obstruction (Correct answer)
Administer antibiotics immediately
Delay resuscitation until meconium is cleared

Correct answer: Routine initial steps without routine tracheal suctioning; only suction the trachea if the newborn is non-vigorous and has airway obstruction

Current guidelines no longer recommend routine tracheal suctioning for vigorous newborns with meconium—intervene only if the newborn shows signs of airway obstruction.

Previous NRP guidelines (pre-2015) recommended routine intubation and tracheal suctioning for all newborns with meconium-stained amniotic fluid. Current guidelines changed this based on evidence showing no benefit. Current recommendations: if the newborn with meconium-stained fluid is vigorous (strong respiratory effort, good muscle tone, heart rate >100 bpm), proceed with routine initial steps without tracheal suctioning. If the newborn is non-vigorous (poor tone, weak respirations, HR <100 bpm), the NRP team should be present—clear the airway with a bulb syringe or suction catheter, and intubation with tracheal suctioning is considered if there is evidence of airway obstruction. PPV should not be delayed for tracheal suctioning in non-vigorous infants.

Question 11: What is the primary cause of cardiac arrest in neonates (versus adults), and how does this affect resuscitation priorities?

Primary cardiac arrhythmia; defibrillation is the priority
Respiratory failure/hypoxia; ventilation and oxygenation are the top priorities before compressions (Correct answer)
Hypovolemia; volume infusion is the first step
Sepsis; antibiotics must be given first

Correct answer: Respiratory failure/hypoxia; ventilation and oxygenation are the top priorities before compressions

Neonatal cardiac arrest is almost always secondary to respiratory failure; effective ventilation takes priority over compressions.

Unlike adult cardiac arrest where the primary cause is often ventricular fibrillation from coronary artery disease, neonatal cardiac arrest is almost always secondary to respiratory failure and resulting hypoxia. This fundamental difference explains why the NRP algorithm prioritizes ventilation over compressions: chest compressions do not oxygenate the blood—only ventilation does. Effective positive-pressure ventilation will restore heart rate in the vast majority of neonates needing resuscitation. Compressions are only started when the heart rate remains <60 bpm despite effective ventilation. Similarly, neonatal VF is very rare, making defibrillation rarely needed. Identifying and correcting the underlying respiratory cause (airway obstruction, hypoventilation) is the key intervention.

Question 12: What does therapeutic hypothermia (targeted temperature management) achieve in neonatal hypoxic-ischemic encephalopathy (HIE)?

It prevents all brain damage from birth asphyxia
It reduces ongoing neuronal death after severe perinatal asphyxia, improving survival and neurological outcomes when initiated within 6 hours (Correct answer)
It increases heart rate in bradycardic neonates
It prevents development of respiratory distress syndrome

Correct answer: It reduces ongoing neuronal death after severe perinatal asphyxia, improving survival and neurological outcomes when initiated within 6 hours

Therapeutic hypothermia (33-34°C for 72 hours) initiated within 6 hours of birth reduces cell death from reperfusion injury in HIE, improving neurological outcomes.

Therapeutic hypothermia (whole-body cooling to 33-34°C for 72 hours) is the standard of care for moderate-to-severe hypoxic-ischemic encephalopathy (HIE) in term and near-term infants (≥36 weeks). Birth asphyxia causes a biphasic brain injury: (1) Primary phase: immediate cell death during hypoxia/ischemia, (2) Secondary phase (6-72 hours): ongoing apoptosis and necrosis from reperfusion injury, excitotoxicity, and inflammation. Therapeutic hypothermia reduces this secondary injury phase, improving survival and reducing severe disability by approximately 25%. It must be initiated within 6 hours of birth (ideally 1-3 hours) to be effective. Eligible infants include those ≥36 weeks with evidence of moderate-to-severe encephalopathy after a sentinel perinatal event.

Question 13: What does 'MR SOPA' stand for in the NRP corrective steps for failed PPV ventilation?

Mask size, Respiration rate, Suction, Oxygen, Pressure, Airway device
Mask adjustment, Reposition airway, Suction mouth and nose, Open mouth, Pressure increase, Alternative airway (Correct answer)
Monitor, Recheck, Stimulate, Oxygen, Position, Assess
Medication, Rewarming, SpO2, Oxygen, Pulse, Airway

Correct answer: Mask adjustment, Reposition airway, Suction mouth and nose, Open mouth, Pressure increase, Alternative airway

MR SOPA is the systematic approach to improving ineffective PPV: Mask adjustment, Reposition, Suction, Open mouth, Pressure increase, Alternative airway.

When PPV is not producing visible chest rise in a newborn, the NRP recommends systematic application of the MR SOPA corrective steps: M = Mask adjustment (ensure a good seal with the mask on the face), R = Reposition the airway (ensure neutral 'sniffing' position), S = Suction the mouth then nose (to clear secretions or meconium), O = Open the mouth (slightly open the infant's mouth), P = Pressure increase (increase the PIP if the airway is patent but chest rise is inadequate), A = Alternative airway (place an endotracheal tube or laryngeal mask if other steps fail). These steps are performed sequentially until adequate chest rise is achieved. Failure to apply MR SOPA corrective steps before starting compressions leads to ineffective resuscitation.

Question 14: What oxygen saturation target range is acceptable at 5 minutes of life for a term newborn during resuscitation?

55-65%
70-75%
80-85% (Correct answer)
90-100%

Correct answer: 80-85%

The NRP SpO2 target at 5 minutes is 80-85% for a term newborn, recognizing that normal transition takes several minutes.

The NRP provides target preductal SpO2 ranges for the first 10 minutes of life to guide oxygen titration during resuscitation. Normal transition from fetal to neonatal circulation takes several minutes, during which SpO2 gradually rises. The targets are: 1 min: 60-65%, 2 min: 65-70%, 3 min: 70-75%, 4 min: 75-80%, 5 min: 80-85%, 10 min: 85-95%. These targets reflect normal physiology—a newly born infant should not be expected to have adult-normal SpO2 values immediately after birth. Supplemental oxygen should only be titrated up if the newborn's SpO2 falls below the target range for age. The pulse oximeter should be placed on the right hand (preductal) for accuracy.

Question 15: What is the preferred vascular access route for medication administration during neonatal resuscitation?

Intraosseous (IO) access in the tibia
Umbilical venous catheter (UVC) (Correct answer)
Peripheral IV in the antecubital fossa
Endotracheal drug administration first

Correct answer: Umbilical venous catheter (UVC)

The umbilical venous catheter (UVC) is the preferred vascular access route in neonatal resuscitation due to rapid placement and proximity to central circulation.

The umbilical vein is the preferred route for vascular access during neonatal resuscitation because: (1) The umbilical cord stump is immediately accessible without any special positioning, (2) A catheter can be placed in the umbilical vein in 30-60 seconds by experienced providers, (3) It provides a central venous route with rapid drug delivery to the heart, (4) It can also be used for volume administration. The catheter should be inserted until blood returns freely and advanced 1-2 cm beyond that point (to prevent hepatic complications). Intraosseous access is an acceptable alternative if UVC cannot be placed. Peripheral IV is difficult to place in distressed neonates. Endotracheal drug delivery is less reliable and lower plasma levels are achieved.

Question 16: Which of the following findings suggests a pneumothorax complicating neonatal resuscitation?

Low blood glucose level
Unilateral decreased breath sounds, hypoxia worsening despite PPV, and shift of the heart sounds to one side (Correct answer)
Normal chest rise with PPV
Persistent bradycardia responsive to epinephrine

Correct answer: Unilateral decreased breath sounds, hypoxia worsening despite PPV, and shift of the heart sounds to one side

Pneumothorax in a neonate presents with asymmetric breath sounds, worsening oxygenation during PPV, and mediastinal shift away from the affected side.

Pneumothorax is a known complication of neonatal resuscitation, particularly in infants with meconium aspiration, lung disease, or those requiring high ventilation pressures. Signs include: unilateral decreased or absent breath sounds on the affected side, cyanosis and desaturation despite seemingly adequate PPV, cardiac sounds shifted to the contralateral side (due to mediastinal shift), and worsening hemodynamic status. Tension pneumothorax can rapidly be fatal if not treated. Emergency treatment involves needle thoracocentesis (aspiration of air from the pleural space using a needle/syringe) on the affected side, followed by chest tube placement. In the resuscitation room, transillumination of the chest can help identify pneumothorax rapidly.

Question 17: When is delayed cord clamping recommended, and what are its benefits?

Immediate clamping is always best; delayed clamping has no proven benefits
For vigorous term and preterm infants not requiring resuscitation, waiting 30-60+ seconds before clamping improves iron stores, hematocrit, and cerebral oxygenation (Correct answer)
Delayed clamping is only beneficial for preterm infants and harms term infants
Cord clamping should always be delayed for at least 5 minutes

Correct answer: For vigorous term and preterm infants not requiring resuscitation, waiting 30-60+ seconds before clamping improves iron stores, hematocrit, and cerebral oxygenation

Delayed cord clamping (≥30-60 seconds for term, ≥30-60 seconds for preterm) benefits infants who don't require immediate resuscitation by increasing blood volume and iron stores.

Current guidelines recommend delayed umbilical cord clamping (DCC) for at least 30-60 seconds for vigorous term and preterm infants not requiring immediate resuscitation. Benefits include: increased blood volume (placental transfusion of 25-35 mL/kg), higher hematocrit and hemoglobin, improved iron stores (reducing iron deficiency anemia in the first year), better cerebral oxygenation in preterm infants, reduced need for blood transfusions in preterm infants, and lower rates of intraventricular hemorrhage and necrotizing enterocolitis in preterm infants. For infants requiring resuscitation, umbilical cord milking (manual expression of cord blood toward the infant) is an alternative being studied. Immediate cord clamping is still practiced when rapid access to the infant is required for resuscitation.

Question 18: What is the NRP recommendation for when to discontinue neonatal resuscitation?

After 5 minutes of unsuccessful resuscitation
Discontinuation is appropriate when there is no detectable heart rate after 10 minutes of complete and adequate resuscitative efforts (Correct answer)
After 2 rounds of epinephrine without response
When the Apgar score remains 0 at 10 minutes

Correct answer: Discontinuation is appropriate when there is no detectable heart rate after 10 minutes of complete and adequate resuscitative efforts

NRP guidelines suggest that discontinuation may be appropriate after 10 minutes of effective resuscitation with no detectable heart rate, though each case requires individual consideration.

The 2020 NRP and AHA guidelines state that, if the heart rate remains undetectable despite 10 minutes of complete, high-quality resuscitation efforts, it is reasonable to discuss stopping resuscitation. However, this is a recommendation, not an absolute rule—the decision should consider contributing factors (cause of arrest, gestational age, availability of therapeutic hypothermia, family wishes, suspected prognosis). An Apgar score of 0 at 10 minutes is associated with very poor survival and neurological outcomes but individual cases with successful resuscitation and good outcomes have been reported. The decision to stop or continue should be made by the team in consultation with family when possible.

Question 19: Which NRP action should be performed in the first 30 seconds after birth for ALL newborns?

Administer surfactant therapy
Perform the initial steps: warm, dry, stimulate, and position (Correct answer)
Attach cardiac monitoring
Obtain a blood gas from the umbilical artery

Correct answer: Perform the initial steps: warm, dry, stimulate, and position

The initial stabilization steps—warming, drying, stimulating, and positioning—apply to every newborn regardless of anticipated condition.

The universal initial steps for every newborn regardless of condition or anticipated risk are: (1) Provide warmth (place under radiant warmer), (2) Dry the infant and remove wet linen, (3) Stimulate by rubbing the back or flicking the soles of the feet, (4) Position the head in a neutral or slightly extended 'sniffing' position to open the airway. These steps prevent heat loss (a major cause of neonatal morbidity) and provide sensory stimulation that triggers spontaneous breathing. For most newborns (~90%), these initial steps are all that is needed. The remaining 10% require some degree of additional support, and a smaller percentage (1-3%) require significant resuscitation. Assessment after the initial steps determines the next action.

Question 20: What is the recommended depth of chest compressions in neonatal CPR?

1 inch (2.5 cm)
One-third of the anteroposterior diameter of the chest (approximately 1.5 inches or 4 cm) (Correct answer)
One-half of the chest diameter
2 inches (5 cm), the same as adults

Correct answer: One-third of the anteroposterior diameter of the chest (approximately 1.5 inches or 4 cm)

Neonatal compressions should compress approximately one-third the anteroposterior chest diameter, about 1.5 inches (4 cm).

The recommended depth for neonatal chest compressions is one-third of the anteroposterior (front-to-back) diameter of the chest, which is approximately 1.5 inches (4 cm) in a term neonate. This proportional approach accommodates the variation in chest sizes between term and preterm infants. Compressions should be firm enough to produce a palpable pulse if possible. After each compression, allow full chest recoil to enable ventricular filling. The compression point is the lower third of the sternum (just below the nipple line), avoiding the xiphoid process. The chest should be compressed downward and released smoothly—avoid jabbing or bouncing compressions.

Question 21: What is the clinical significance of the 'pre-ductal' pulse oximeter placement on the right hand during neonatal resuscitation?

The right hand is easier to access during delivery
Pre-ductal SpO2 reflects oxygen saturation of blood before it passes through the ductus arteriosus, providing a more accurate picture of cerebral and coronary oxygenation (Correct answer)
Right-hand placement avoids interference from IV lines
Pre-ductal monitoring is required by regulatory agencies

Correct answer: Pre-ductal SpO2 reflects oxygen saturation of blood before it passes through the ductus arteriosus, providing a more accurate picture of cerebral and coronary oxygenation

Pre-ductal SpO2 (right hand) reflects oxygenation before the ductus arteriosus and represents the oxygen delivery to the brain and heart.

In neonates, the ductus arteriosus (a fetal blood vessel connecting the pulmonary artery to the aorta) may still be open and allows mixing of oxygenated and deoxygenated blood. 'Pre-ductal' refers to blood that has been ejected from the left ventricle before reaching the ductus arteriosus junction—this blood supplies the brain, heart, and right arm. 'Post-ductal' blood (left arm and legs) may have lower SpO2 due to mixing with desaturated pulmonary shunt blood. Placing the pulse oximeter on the right hand (pre-ductal) gives the most accurate representation of cerebral and coronary oxygen delivery. This is the reference position for the NRP target SpO2 values and guides oxygen titration during the first minutes of life.

Question 22: What underlying causes should be considered when a neonate fails to respond to standard resuscitation (termed 'persistent bradycardia')?

Only cardiac arrhythmia and hypoglycemia
Airway problems, inadequate ventilation, hypovolemia, tension pneumothorax, congenital anomalies, and metabolic abnormalities (Correct answer)
Only maternal medications and prematurity
Hypoglycemia and temperature instability alone

Correct answer: Airway problems, inadequate ventilation, hypovolemia, tension pneumothorax, congenital anomalies, and metabolic abnormalities

When standard resuscitation fails, systematically consider airway issues, hypovolemia, pneumothorax, congenital anomalies, and metabolic causes.

When a neonate fails to respond to standard resuscitation (effective PPV and compressions plus epinephrine), the team should systematically consider: (1) Airway problems (misplaced ETT, obstruction, choanal atresia), (2) Inadequate ventilation (equipment failure, poor technique), (3) Hypovolemia (blood loss from abruptio placentae, fetal-maternal hemorrhage, cord accident)—treat with normal saline 10 mL/kg IV, (4) Tension pneumothorax—needle decompression, (5) Congenital anomalies affecting the heart (cardiac malformations) or lungs (diaphragmatic hernia, pulmonary hypoplasia), (6) Metabolic abnormalities (severe acidosis, hypoglycemia, hyperkalemia), (7) Severe anemia requiring packed red blood cells. Careful re-assessment at each step is essential.

Question 23: What is the 'sniffing position' in neonatal airway management?

Hyperextension of the neck as used in adult CPR
A slight extension of the neck, as if the baby is sniffing a flower, which aligns the pharyngeal and tracheal axes to optimize the airway (Correct answer)
Flexion of the neck to protect against cervical injury
The position of the infant's nostrils during suctioning

Correct answer: A slight extension of the neck, as if the baby is sniffing a flower, which aligns the pharyngeal and tracheal axes to optimize the airway

The sniffing position involves slight neck extension that aligns the oral, pharyngeal, and tracheal axes for optimal airway patency in neonates.

The sniffing position is the optimal head position for neonatal airway management: the neck is in a neutral-to-slightly-extended position, as if the infant is about to sniff a flower. This aligns the oral, pharyngeal, and tracheal axes, creating the most direct route for air passage and tracheal intubation. Over-extension (hyperextension) can cause airway obstruction in neonates because the relatively large occipital prominence causes the neck to flex when the infant is on a flat surface—a small towel roll under the shoulders helps achieve the sniffing position. Flexion causes the tongue to fall back and obstruct the airway. The correct position is often underappreciated as a cause of failed PPV—repositioning is the second step of MR SOPA corrective actions.

Question 24: What is surfactant therapy in the context of neonatal care, and when is it indicated?

A medication given to prevent meconium aspiration in all newborns
A substance given to preterm infants to treat respiratory distress syndrome (RDS) by reducing alveolar surface tension and preventing alveolar collapse (Correct answer)
A drug given to correct neonatal hypoglycemia
An antibiotic given for suspected neonatal sepsis

Correct answer: A substance given to preterm infants to treat respiratory distress syndrome (RDS) by reducing alveolar surface tension and preventing alveolar collapse

Exogenous surfactant is given to preterm infants with RDS to replace deficient natural surfactant, reducing alveolar collapse and improving oxygenation.

Pulmonary surfactant is a complex phospholipid-protein mixture produced by type II alveolar cells that reduces alveolar surface tension and prevents alveolar collapse at end-expiration. Preterm infants lack adequate surfactant production (typically under 32-34 weeks), leading to respiratory distress syndrome (RDS)—characterized by progressive respiratory failure, grunting, retractions, and hypoxia. Exogenous surfactant replacement therapy (animal-derived or synthetic surfactant) administered via endotracheal tube dramatically improves outcomes in preterm infants with RDS, reducing mortality, chronic lung disease, and pneumothorax. Prophylactic surfactant (given to all very preterm infants immediately after birth) has been largely replaced by early rescue surfactant given after confirming RDS diagnosis.

Question 25: What are the 'five H's' assessed during neonatal resuscitation to identify specific causes requiring targeted treatment?

Hypercarbia, Hypertension, Hyperthermia, Hemolysis, Hyperglycemia
Hypothermia, Hypovolemia, Hypoxia, Hypoglycemia, Hypo/Hypercarbia (Correct answer)
Heart rate, Heartbeat, Hypoventilation, Hemorrhage, Hypotension
Hydration, Homeostasis, Hemoglobin, Hyperventilation, Hypocalcemia

Correct answer: Hypothermia, Hypovolemia, Hypoxia, Hypoglycemia, Hypo/Hypercarbia

During neonatal resuscitation, these five H's represent common reversible causes that can complicate or drive persistent bradycardia and poor response.

During neonatal resuscitation, when a newborn is not responding as expected, the team should actively assess for and treat these common H-causes: (1) Hypothermia—rewarm with radiant warmer, avoid cold stress, (2) Hypovolemia—consider in cases of known blood loss (abruptio placenta, cord accident), treat with saline bolus 10 mL/kg, (3) Hypoxia—ensure adequate PPV, correct airway problems, (4) Hypoglycemia—check blood glucose (particularly important for infants of diabetic mothers, growth-restricted, or stressed infants), treat with dextrose infusion, (5) Hypo/Hypercarbia—excessive CO2 reduces cardiac contractility; too little causes cerebral vasoconstriction. These targeted interventions address root causes rather than just treating the symptom.

Question 26: A premature infant born at 28 weeks gestation requires resuscitation. Which additional consideration applies compared to a term infant?

Use 100% oxygen immediately for all preterm infants
Use a polyethylene wrap to prevent heat loss, use higher initial FiO2 (21-30%), consider CPAP for respiratory support, and be aware of increased risk of intraventricular hemorrhage from aggressive interventions (Correct answer)
Perform immediate endotracheal intubation regardless of clinical condition
Use deeper compressions due to more developed chest wall

Correct answer: Use a polyethylene wrap to prevent heat loss, use higher initial FiO2 (21-30%), consider CPAP for respiratory support, and be aware of increased risk of intraventricular hemorrhage from aggressive interventions

Preterm infants require special considerations including temperature management (polyethylene bag), judicious oxygen use, and CPAP, with attention to fragile cerebral vessels.

Preterm infants, especially those <32 weeks, require special resuscitation considerations: (1) Temperature: immediately place in a polyethylene plastic bag/wrap (without drying) under the radiant warmer to prevent evaporative heat loss—critical since preterm infants lose heat rapidly, (2) Oxygen: start with 21-30% FiO2 (not 21% as for term), titrating with SpO2 monitoring, (3) Respiratory support: CPAP (continuous positive airway pressure) is preferred over immediate intubation for spontaneously breathing preterm infants with respiratory distress, (4) Avoid aggressive handling: intraventricular hemorrhage (IVH) risk is high, particularly with rapid blood pressure changes, (5) Surfactant: anticipate early rescue surfactant for RDS, (6) Lower compression depth due to smaller, more compliant chest.

Question 27: What is 'Kangaroo Mother Care' (KMC) and its benefit for premature or low birth weight infants?

A surgical procedure for very preterm infants
Skin-to-skin contact between the caregiver and infant that stabilizes temperature, promotes breastfeeding, and improves survival and neurodevelopmental outcomes in preterm/LBW infants (Correct answer)
A type of incubator used in neonatal intensive care
A feeding technique using specialized formula

Correct answer: Skin-to-skin contact between the caregiver and infant that stabilizes temperature, promotes breastfeeding, and improves survival and neurodevelopmental outcomes in preterm/LBW infants

KMC involves continuous skin-to-skin contact, breastfeeding support, and early discharge with monitoring—dramatically reducing mortality in premature and low birth weight infants.

Kangaroo Mother Care (KMC) is a WHO-recommended intervention for premature (born before 37 weeks) and low birth weight (LBW, <2500 g) infants in which the infant is held skin-to-skin on the parent's or caregiver's chest in an upright position, with breastfeeding support and early discharge home with close follow-up. Benefits include: thermoregulation through transfer of body heat, promotion of breastfeeding, stabilization of heart rate and breathing, improved weight gain, reduced infection rates, better neurodevelopmental outcomes, reduced NICU stay duration, and lower neonatal mortality (36% reduction in mortality for stable preterm infants <2000g per WHO evidence). KMC is particularly vital in resource-limited settings where incubator care is unavailable.

Question 28: What does the NRP '30-second rule' refer to?

Wait 30 seconds after birth before cutting the umbilical cord (Correct answer)
Complete initial assessment within 30 seconds and begin PPV if needed by the end of the Golden Minute (60 seconds)
Give PPV for exactly 30 seconds before assessing heart rate
Administer epinephrine after 30 seconds of inadequate response

Correct answer: Wait 30 seconds after birth before cutting the umbilical cord

NRP recommends delayed cord clamping for at least 30-60 seconds in stable infants, while initial steps occur simultaneously or within 30 seconds.

In the NRP context, the '30-second rule' primarily refers to delayed umbilical cord clamping—for vigorous term and preterm infants not requiring immediate resuscitation, the cord should not be clamped for at least 30-60 seconds (some guidelines recommend up to 60-180 seconds). During this time, the initial stabilization steps (warm, dry, stimulate, position) can be performed in place or with the infant slightly lowered to be level with the placenta. This allows placental transfusion of 25-35 mL/kg of blood with its oxygen-carrying capacity and iron stores. The 30-second delayed cord clamping is now recommended by WHO, ACOG, and NRP for stable newborns, with growing evidence supporting even longer delays.

Question 29: What is the role of positive end-expiratory pressure (PEEP) in neonatal bag-valve-mask ventilation?

PEEP is never used in neonatal resuscitation
PEEP maintains airway patency and functional residual capacity (FRC) between breaths, preventing atelectasis especially in preterm lungs (Correct answer)
PEEP increases compression rate during CPR
PEEP is used to dry secretions in the airway

Correct answer: PEEP maintains airway patency and functional residual capacity (FRC) between breaths, preventing atelectasis especially in preterm lungs

PEEP prevents alveolar collapse between PPV breaths, maintaining FRC—especially important in preterm infants with surfactant-deficient lungs.

Positive end-expiratory pressure (PEEP) during neonatal PPV maintains a small amount of pressure in the airway between breaths (typically 5 cmH₂O), preventing the alveoli from collapsing completely at end-expiration. This is particularly important in preterm infants with surfactant deficiency and tendency for alveolar collapse (atelectasis). T-piece resuscitators (Neopuff) can reliably deliver PEEP, while traditional self-inflating bags cannot deliver PEEP without an additional PEEP valve. Flow-inflating bags can deliver PEEP when properly adjusted. Sustained inflation breaths (used in some units as 'recruitment maneuvers') remain controversial in NRP, but maintaining PEEP during ongoing PPV is endorsed. Consistent PEEP delivery contributes to more uniform lung recruitment and better oxygenation in the first minutes of life.

Question 30: What is 'neonatal abstinence syndrome' (NAS) and how does it affect newborn resuscitation considerations?

NAS is a vitamin deficiency syndrome in newborns
NAS is a withdrawal syndrome in newborns born to mothers who used opioids or other substances during pregnancy, causing irritability, feeding difficulties, and potentially requiring pharmacological management (Correct answer)
NAS is a type of neonatal sepsis
NAS means the baby cannot be resuscitated with standard methods

Correct answer: NAS is a withdrawal syndrome in newborns born to mothers who used opioids or other substances during pregnancy, causing irritability, feeding difficulties, and potentially requiring pharmacological management

NAS is opioid withdrawal in newborns of mothers who used opioids; these infants may need resuscitation modified for their physiological state and ongoing neonatal management.

Neonatal abstinence syndrome (NAS), also called neonatal opioid withdrawal syndrome (NOWS) when opioid-specific, occurs in infants born to mothers who used opioids (heroin, methadone, buprenorphine, prescription opioids) during pregnancy. The fetus becomes physically dependent on opioids in utero; withdrawal begins hours to days after birth. Symptoms include: high-pitched cry, irritability, poor feeding, tremors, increased muscle tone, yawning/sneezing, fever, vomiting, and diarrhea. Resuscitation considerations: NAS itself does not typically require resuscitation unless the infant has been acutely opioid-exposed near delivery causing respiratory depression (may need naloxone, though standard NRP does not recommend routine naloxone for maternal opioid use). NAS management involves non-pharmacological measures (skin-to-skin, swaddling, low stimulation) and pharmacological treatment (morphine or methadone) when needed.

Question 31: What is the primary reason continuous positive airway pressure (CPAP) is preferred over immediate intubation for breathing preterm infants with respiratory distress?

CPAP is cheaper than intubation supplies
CPAP avoids the risks of intubation (trauma, infection, ventilator-induced lung injury) and allows the infant's own respiratory effort to contribute to breathing (Correct answer)
CPAP delivers higher oxygen concentrations
CPAP is easier to perform without specialized training

Correct answer: CPAP avoids the risks of intubation (trauma, infection, ventilator-induced lung injury) and allows the infant's own respiratory effort to contribute to breathing

CPAP supports breathing while preserving spontaneous respiratory effort, avoiding the significant risks associated with endotracheal intubation and mechanical ventilation.

The SUPPORT and COIN trials (and subsequent NRP guideline updates) established that for spontaneously breathing preterm infants (≥25-26 weeks) with respiratory distress, early CPAP (5-8 cmH₂O via nasal prongs or mask) is at least as effective as immediate intubation and surfactant, with fewer adverse effects. CPAP maintains airway pressure throughout the respiratory cycle, recruits and stabilizes alveoli, reduces work of breathing, and allows the infant to use their own diaphragm. Risks of routine early intubation include: airway trauma, ventilator-associated pneumonia, and ventilator-induced lung injury (barotrauma, volutrauma). Current NRP recommends: for spontaneously breathing preterm infants >30 weeks with RDS, start CPAP; for non-breathing or extremely preterm infants requiring PPV, intubate for surfactant administration then extubate to CPAP (INSURE strategy).

Question 32: What is the significance of measuring blood glucose in newborns after resuscitation?

Blood glucose levels guide the rate of chest compressions
Hypoglycemia is a common complication post-resuscitation that can worsen brain injury if untreated; glucose should be measured and maintained >45-50 mg/dL (Correct answer)
High blood glucose predicts better neurological outcome
Glucose measurement is only needed if the infant has seizures

Correct answer: Hypoglycemia is a common complication post-resuscitation that can worsen brain injury if untreated; glucose should be measured and maintained >45-50 mg/dL

Post-resuscitation hypoglycemia is common and worsens hypoxic-ischemic brain injury; early glucose measurement and supplementation are essential.

Hypoglycemia is a critical post-resuscitation concern in newborns for several reasons: (1) Stressed neonates deplete glycogen stores rapidly during asphyxia and resuscitation, (2) Neonates have limited ability to maintain glucose through gluconeogenesis, (3) Hypoglycemia independently worsens neurological injury—glucose is the brain's primary fuel, and hypoglycemia during the post-ischemic recovery period amplifies neuronal death. All resuscitated neonates should have blood glucose measured within 30-60 minutes of birth and maintained ≥45-50 mg/dL (some guidelines say >50 mg/dL post-resuscitation). Treatment involves early enteral feeding (if tolerating) or intravenous dextrose infusion. Glucose monitoring should continue for at least 12-24 hours in resuscitated infants, with particular attention to infants of diabetic mothers, preterm, and growth-restricted infants.

Question 33: What is the purpose of the NRP assessment mnemonic 'STABLE' in post-resuscitation stabilization?

It describes the steps of chest compressions
It is a post-resuscitation stabilization framework: Sugar, Temperature, Airway, Blood pressure, Lab work, Emotional support (Correct answer)
It defines criteria for stopping resuscitation
It guides tracheal intubation technique

Correct answer: It is a post-resuscitation stabilization framework: Sugar, Temperature, Airway, Blood pressure, Lab work, Emotional support

STABLE guides post-resuscitation stabilization: Sugar (glucose), Temperature, Airway, Blood pressure, Lab work, and Emotional support for families.

The STABLE program is a post-resuscitation and pre-transport stabilization program for ill neonates: S = Sugar (blood glucose management—target ≥50 mg/dL, IV dextrose if needed), T = Temperature (maintain normothermia 36.5-37.5°C; actively warm hypothermic infants; avoid hyperthermia which worsens HIE), A = Airway (confirm secure airway, endotracheal tube position, adequate ventilation, suction as needed), B = Blood pressure (assess perfusion, treat hypotension with volume and vasopressors), L = Lab work (blood gas, glucose, CBC, CRP, blood culture if infection suspected, electrolytes), E = Emotional support (communicate with family, address questions and fears). The STABLE mnemonic helps providers systematically address the common post-resuscitation complications before transport to the NICU.

Question 34: In neonatal resuscitation, when is sodium bicarbonate administration appropriate?

Routinely for all depressed newborns to correct acidosis
Only in prolonged arrests with documented severe metabolic acidosis (pH <7.0) after adequate ventilation has been established, and only IV/IO never endotracheal (Correct answer)
For every round of epinephrine given
Routinely after 10 minutes of CPR

Correct answer: Only in prolonged arrests with documented severe metabolic acidosis (pH <7.0) after adequate ventilation has been established, and only IV/IO never endotracheal

Sodium bicarbonate is rarely used in NRP—only for documented severe metabolic acidosis after adequate ventilation is confirmed; routine use is harmful.

Sodium bicarbonate use in neonatal resuscitation has become increasingly controversial and restricted. Current NRP guidelines recommend considering it only in prolonged resuscitation with documented severe metabolic acidosis (pH <7.0 or base deficit >10) AND only after adequate ventilation has been established—because bicarbonate generates CO₂ which can worsen intracellular acidosis if the CO₂ cannot be exhaled (hence the requirement for confirmed ventilation). Routine sodium bicarbonate use in cardiac arrest is not recommended because: (1) Evidence of benefit is lacking, (2) It generates CO₂ (worsens cellular acidosis if ventilation is inadequate), (3) Causes hyperosmolarity and hypernatremia, (4) Has been associated with intraventricular hemorrhage in preterm infants. Dose: 1-2 mEq/kg of 0.5 mEq/mL solution, slow IV push over at least 2 minutes.

Question 35: What is the role of video laryngoscopy in neonatal intubation?

Video laryngoscopy is not approved for neonatal use
Video laryngoscopy improves visualization of the neonatal glottis and increases intubation success rates, particularly for trainees and in difficult airways (Correct answer)
It replaces the need for experienced providers at high-risk deliveries
Video laryngoscopy causes more airway trauma than direct laryngoscopy in neonates

Correct answer: Video laryngoscopy improves visualization of the neonatal glottis and increases intubation success rates, particularly for trainees and in difficult airways

Video laryngoscopy improves glottic visualization and first-attempt success in neonatal intubation, especially for trainees and challenging anatomical situations.

Video laryngoscopy (VL) uses a blade with a camera that displays the airway on a screen, allowing the intubating provider and team to simultaneously see the larynx. In neonatal resuscitation, VL offers several advantages: (1) Improved first-attempt intubation success rates compared to direct laryngoscopy, particularly for trainees, (2) Ability for supervisors to see exactly what the intubator sees and provide real-time guidance, (3) Useful for anatomically difficult airways (micrognathia, retrognathia, cleft lip/palate), (4) Reduces time to intubation in skilled hands. Limitations include: equipment cost, learning curve, need for specialized neonatal-sized blades, and slight delay versus experienced direct laryngoscopists. Growing evidence supports VL as a useful adjunct in neonatal intubation programs, particularly for training and difficult airway management.

Question 36: What special precaution should be taken for extremely preterm infants (<28 weeks) regarding cord clamping at delivery?

Always immediately clamp the cord to prevent blood loss
Delayed cord clamping for 30-60 seconds is recommended if the infant is stable; umbilical cord milking is an acceptable alternative if immediate resuscitation is needed (Correct answer)
Cord milking is contraindicated in all preterm infants
Cord clamping timing doesn't matter for extremely preterm infants

Correct answer: Delayed cord clamping for 30-60 seconds is recommended if the infant is stable; umbilical cord milking is an acceptable alternative if immediate resuscitation is needed

Delayed cord clamping or umbilical cord milking provides significant iron stores and blood volume to extremely preterm infants, reducing transfusion needs and IVH risk.

For extremely preterm infants (<28 weeks), the blood available for placental transfusion represents a significant proportion of the infant's total blood volume. Benefits of delayed cord clamping (30-60 seconds) or intact cord resuscitation include: higher initial blood pressure and better circulatory transition, lower rates of intraventricular hemorrhage (IVH), reduced need for early blood transfusions, reduced rates of necrotizing enterocolitis, and potentially improved neurodevelopmental outcomes. When immediate resuscitation is needed and the team cannot wait, umbilical cord milking (manually massaging blood from the cord toward the infant 4-5 times) is an acceptable alternative that can be performed in 10-15 seconds. Extremely preterm facilities are increasingly implementing 'bedside resuscitation' where the resuscitation is performed with the umbilical cord intact, allowing both delayed clamping and simultaneous resuscitation.
