What should you avoid during breath delivery in CPR?

During breath delivery in CPR, it is essential to avoid excessive ventilation. This practice can lead to complications, such as increased intrathoracic pressure, which may hinder blood flow to the heart and reduce overall circulation. Over-inflating the lungs can also cause air to enter the stomach, increasing the risk of aspiration, which can lead to further complications during resuscitation.

Maintaining an adequate balance in ventilation is crucial; breaths should be delivered just enough to make the chest rise visibly. This ensures that air is entering the lungs effectively without causing harm. Proper technique allows for the optimal exchange of oxygen and carbon dioxide, which is vital in a cardiac arrest scenario where the victim’s oxygen levels are already compromised. Therefore, it's crucial to focus on delivering breaths that are not too forceful or too rapid, ensuring effective CPR while avoiding potential negative outcomes associated with excessive ventilation.
