What is the importance of chest recoil during CPR?

Chest recoil during CPR is crucial because it allows the heart to refill with blood between compressions. When you perform chest compressions, you compress the chest, which helps to push blood out of the heart and into the circulation. However, it’s equally important to allow the chest to fully recoil after each compression. This recoil creates a negative pressure in the thoracic cavity, which facilitates venous return to the heart, enabling it to fill with blood again. If the chest does not fully recoil, the amount of blood that can return to the heart is reduced, which can lead to ineffective CPR and a decreased chance of survival. Proper chest recoil optimizes the effectiveness of the compressions, ensuring that blood flow circulates adequately.
