What is one critical action to ensure quality during CPR?

Allowing the chest to fully recoil after each compression is a critical action during CPR because it maximizes the return of blood to the heart between compressions. This allows the heart to fill with blood more efficiently, which is essential for maintaining adequate blood flow and oxygen delivery to vital organs during cardiac arrest. When the chest does not fully recoil, the quality of compressions decreases and can lead to reduced cardiac output. Proper recoil enables the heart to effectively reclaim the capacity necessary for subsequent compressions, thus enhancing the effectiveness of CPR overall.

In performing high-quality CPR, it is essential to maintain a proper compression depth and rate, but equally important is the complete release of pressure on the chest after each compression. This balance allows for optimal circulation and improves the likelihood of a successful resuscitation.
