Why is it important to maintain chest recoil during CPR?

Maintaining chest recoil during CPR is crucial because it allows the heart to refill with blood between compressions. When you compress the chest, blood is pushed out of the heart and into circulation. Releasing the pressure allows the chest to return to its normal position, which creates negative pressure within the thoracic cavity. This negative pressure helps draw blood back into the heart, particularly into the right atrium, preparing it for the next compression. Without adequate chest recoil, the heart does not refill properly, which can significantly reduce blood flow to vital organs during CPR, making the compressions less effective.

Focusing on effective chest recoil is essential for maximizing the effectiveness of CPR, as it optimizes blood return and enhances overall blood circulation during each cycle of compressions.
