What is the correct rate of ventilation delivery for an adult patient with an endotracheal tube (ET) in place during CPR?

The appropriate rate of ventilation delivery for an adult patient with an endotracheal tube in place during cardiopulmonary resuscitation (CPR) is one ventilation every 6 seconds. This equates to a total of 10 breaths per minute.

When performing CPR, it's essential to ensure that the ventilations are effective and that they occur at a steady rate to avoid excessive hyperventilation, which can lead to complications such as decreased blood return to the heart and increased intrathoracic pressure. The 1 ventilation every 6 seconds guideline is based on evidence to maintain adequate oxygenation while allowing sufficient time for the chest to re-expand between breaths.

This rate is specifically indicated for advanced airway management scenarios, including the use of an endotracheal tube, where the focus is on providing adequate oxygenation without disrupting the circulation that is critical during CPR efforts.
