How long should rescue breaths last during CPR?

During CPR, rescue breaths should last about 1 second each. This duration is ideal because it allows adequate time for the air to enter the lungs without overinflating them, which can cause complications such as gastric inflation and decreased lung effectiveness. The goal of the rescue breaths is to deliver sufficient oxygen to the patient’s lungs while minimizing the risk of injury.

In pediatric care, especially when dealing with children and infants, the breaths should be gentle and sufficient to see the chest rise visibly. This method ensures that the breaths are effective, promoting optimal oxygenation. Understanding this timing is crucial, as it helps maintain a proper rhythm and balance within the CPR process while still being mindful of the specific anatomical considerations related to children and infants.
