Oxygenation and ventilation: Once the position and seal are obtained, bagging can commence. The rate of ventilation for an adult is 10-12 breaths per minute or, approximately 1 bag squeeze every 5-6 seconds.4 The bag should be depressed for a full 1-2 seconds and then released.
This unique mode of ventilation results in higher average airway pressures. Patients are able to spontaneously ventilate at both low and high pressures, although typically most (or all) ventilation occurs at the high pressure. In the absence of attempted breaths, APRV and PCIRV are identical.
