Which ventilator mode delivers a set tidal volume regardless of changes in lung compliance?
Answer: Volume Control (VC)
Volume Control ventilation delivers a preset tidal volume with each breath regardless of airway resistance or compliance changes.
A patient's ABG shows pH 7.28, PaCO2 55 mmHg, HCO3 25 mEq/L. What is the primary disturbance?
Answer: Respiratory acidosis
Elevated PaCO2 with low pH and normal HCO3 indicates uncompensated respiratory acidosis.
Which bronchodilator is classified as a short-acting beta-2 agonist (SABA)?
Answer: Albuterol
Albuterol is a SABA with onset of action within minutes and duration of 4-6 hours.
The normal range for PaO2 in a healthy adult breathing room air at sea level is:
Answer: 75-100 mmHg
Normal PaO2 for a healthy adult at sea level breathing room air is 75-100 mmHg.
Which of the following is the MOST appropriate initial FiO2 for a patient with COPD presenting with acute exacerbation and mild hypoxemia?
Answer: 0.28 (28%)
COPD patients should receive controlled low-flow oxygen (24-28%) to avoid suppressing hypoxic drive.
Which parameter is used to assess auto-PEEP (intrinsic PEEP) in a mechanically ventilated patient?
Answer: End-expiratory pause pressure
An end-expiratory pause maneuver on the ventilator reveals auto-PEEP by measuring pressure trapped at end expiration.
A patient is receiving mechanical ventilation with a plateau pressure of 34 cmH2O. According to ARDS Network guidelines, what is the recommended action?
Answer: Reduce tidal volume
ARDSNet guidelines recommend reducing tidal volume to keep plateau pressure ≤30 cmH2O to prevent ventilator-induced lung injury.
