During CPR, how often should breaths be provided when an advanced airway is in place?

When an advanced airway, such as an endotracheal tube, is in place during CPR, breaths should be provided at a rate of 6 to 8 seconds. This corresponds to a frequency of about 8 to 10 breaths per minute. Providing breaths within this range ensures that the patient receives adequate ventilation while minimizing the risk of hyperventilation, which can occur if breaths are given too quickly.

The rationale behind the recommended timing takes into account the need for sufficient time to deliver each breath effectively and observe the chest rise, which indicates that ventilations are being administered properly. The focus shifts during CPR with an advanced airway, allowing for continuous chest compressions without the interruption of ventilations that occurs in scenarios without such an airway. This method helps maintain blood circulation and oxygenation until advanced help arrives or spontaneous circulation is restored.
