Question: 1 / 400

How long should each rescue breath last during CPR?

2 seconds

1 second

In Cardiopulmonary Resuscitation (CPR), each rescue breath should last about 1 second. This duration allows for proper inflation of the lungs, ensuring that the air is delivered effectively to the patient. The goal is to make each breath sufficient enough to create visible chest rise, indicating that air is entering the lungs. Administering breaths that are too short may not provide adequate ventilation, while breaths that last significantly longer (like 2 seconds or more) could increase the risk of complications such as air entering the stomach instead of the lungs, leading to ineffective resuscitation efforts. Hence, aiming for a duration of around 1 second is optimal for effective rescue breathing during CPR.
