What is the ventilation rate during CPR when using a manual bag ventilator?

6 breaths per minute 8 breaths per minute 10 breaths per minute 12 breaths per minute

Correct Answer:

10 breaths per minute

Explanation:

During CPR with a manual bag, the aim is to provide enough ventilation to support oxygenation without compromising circulation. The standard target is about ten breaths per minute. This cadence lines up with delivering two breaths after every set of chest compressions (roughly 30 compressions), given a typical compression rate of about 100 per minute. That balance keeps ventilation adequate while minimizing interruptions and preventing excessive airway pressures that can hinder venous return and cardiac output. Ventilating more rapidly risks hyperventilation and higher intrathoracic pressures; too few breaths can lead to inadequate oxygen delivery.
