How deep should chest compressions be applied on an adult?

The depth of chest compressions for an adult during cardiopulmonary resuscitation (CPR) is recommended to be at least 2 inches. This depth is essential for ensuring that sufficient pressure is applied to the heart, which is located behind the sternum, allowing for effective compression of the heart to circulate blood. Research and guidelines provided by organizations such as the American Heart Association emphasize the importance of reaching this depth to generate adequate blood flow during cardiac arrest.

Compressions that are too shallow may not effectively pump blood to vital organs, compromising the chances of survival. The goal is to compress to a depth of 2 inches while allowing full recoil of the chest between compressions, which further aids in effective circulation. This practice aligns with current lifesaving protocols, underscoring the importance of following established guidelines in emergency situations.
