What is the minimum interruption time for chest compressions when delivering ventilations?

The correct minimum interruption time for chest compressions when delivering ventilations is 10 seconds. This guideline is based on the need to maximize the efficacy of chest compressions while ensuring that adequate oxygenation can still occur during rescue breaths.

Chest compressions are critical in maintaining circulation and perfusion of vital organs during a cardiac arrest. Each pause for ventilation should be minimized to avoid significant interruptions in blood flow. At 10 seconds, the interruption allows for the delivery of two effective breaths while still prioritizing the continuation of compressions, which are essential for maintaining cardiac output. This balance is crucial in managing a patient in a critical situation, ensuring they receive both adequate ventilation and perfusion.

While there are variations in practice, adhering to this guideline supports best practices in advanced life support protocols, aiming to optimize patient outcomes in emergencies.
