NREMT Paramedic Cognitive ExamAirway, Respiration & VentilationHard
A 6-month-old infant is apneic and pulseless. After initiating CPR, you are preparing to ventilate with a bag-valve-mask (BVM). What is the appropriate ventilation rate for this infant during CPR?
- A30-40 breaths per minute (1 breath every 1.5-2 seconds)
- B10-12 breaths per minute (1 breath every 5-6 seconds)
- C20-30 breaths per minute (1 breath every 2-3 seconds)
- D12-20 breaths per minute (1 breath every 3-5 seconds)
Show answer & explanationAnswer & explanation
Correct answer: C. 20-30 breaths per minute (1 breath every 2-3 seconds)
During CPR for an infant, the recommended ventilation rate is 20-30 breaths per minute, which translates to approximately 1 breath every 2-3 seconds. This higher rate is necessary for infants due to their higher metabolic rate and smaller lung volumes, ensuring adequate oxygenation while minimizing interruptions to chest compressions.
Why the other options are wrong
- A. This rate is too fast and could lead to hyperventilation, which can decrease cardiac output by increasing intrathoracic pressure.
- B. This rate is appropriate for adults (10-12 bpm) during CPR, not infants.
- D. This rate (12-20 bpm) is typically for children during CPR, but infants require a slightly faster rate.
Infant CPR Ventilation Rate
During cardiopulmonary resuscitation (CPR) for infants, the recommended ventilation rate is 20-30 breaths per minute (1 breath every 2-3 seconds) to provide adequate oxygenation without causing hyperventilation, which can compromise circulation.
- Infants have higher metabolic rates and smaller lung capacities.
- Higher ventilation rate compared to adults/children.
- Avoid hyperventilation as it can decrease cardiac output.
