Read the first 7 Defibrillation & Airway Management flashcards as text

  1. During endotracheal intubation confirmation, bilateral breath sounds are heard but the ETCO2 detector shows no color change after 6 breaths. What is the most likely cause?

    Answer: Esophageal intubation has occurred

    Absence of CO2 on colorimetric capnography after 6 breaths strongly indicates esophageal intubation, which requires immediate tube removal and reintubation.

  2. What is the maximum recommended time for interrupting chest compressions to deliver ventilations with an advanced airway in place?

    Answer: No interruption needed; ventilate every 6 seconds asynchronously

    Once an advanced airway is secured, ventilations should be delivered every 6 seconds (10/min) asynchronously without pausing chest compressions.

  3. Which rhythm is described as an organized, regular, narrow-complex rhythm WITHOUT a pulse?

    Answer: Pulseless electrical activity (PEA)

    PEA is characterized by an organized ECG rhythm with no detectable pulse, and it is treated with CPR and epinephrine rather than defibrillation.

  4. In a patient with a hairy chest, the best immediate action before placing AED pads is to:

    Answer: Quickly shave or wipe the pad area to improve contact

    Chest hair can prevent adequate pad-skin contact, increasing impedance; rapid removal by shaving or using the first set of pads to wipe hair improves shock delivery.

  5. A laryngeal mask airway (LMA) is inserted and ventilation begins. Chest rise is absent despite proper technique. What is the FIRST corrective action?

    Answer: Remove the LMA and perform BVM ventilation

    If an LMA fails to provide adequate ventilation, it should be removed immediately and basic BVM ventilation resumed while preparing for another attempt.

  6. How should AED pads be positioned for an infant during cardiac arrest?

    Answer: Anterior chest and posterior back (anterior-posterior)

    For infants, anterior-posterior pad placement is recommended because the small chest makes standard adult pad positioning impractical and risky.

  7. During two-rescuer CPR, the compressor and ventilator roles should be switched approximately every:

    Answer: 2 minutes

    Rescuers should switch compressor roles every 2 minutes (or 5 cycles of CPR) to prevent fatigue-related decline in compression quality.
