What is a key component of high-quality compressions in CPR?

A key component of high-quality compressions in CPR is compression depth. The effectiveness of cardiopulmonary resuscitation largely depends on the adequacy of chest compressions, which are designed to mimic the pumping action of the heart. The recommended depth for adult compressions is at least 2 inches (5 cm) and not more than 2.4 inches (6 cm). This depth ensures that enough pressure is applied to the heart to generate sufficient blood flow to vital organs, particularly the brain and heart, during cardiac arrest.

Achieving the proper compression depth helps to maximize venous return to the heart and improves the chances of restoring a viable heart rhythm. If compressions are too shallow, they may be ineffective in circulating blood, which can significantly diminish the chances of survival for the victim. Thus, maintaining an appropriate compression depth is critical for high-quality CPR.

In contrast, breath volume refers to the amount of air delivered during rescue breaths, pulse monitoring pertains to checking for a pulse rather than administering compressions, and victim age does not directly influence the technique of performing compressions effectively.
