What is the recommended depth of compressions for adults and children?

The recommended depth of compressions for adults and children during CPR is 2 inches. This depth is based on extensive research and guidelines established by the American Heart Association. Compressions at this depth are necessary to effectively create adequate blood flow to the vital organs, particularly the brain and heart, during cardiac arrest.

The choice of 2 inches strikes a balance between being effective in compressing the chest to pump blood and ensuring the safety of the patient, as excessive compression depth could lead to injuries such as rib fractures. In adults, a depth of at least 2 inches (5 cm) provides the necessary pressure for circulatory efficacy, while for children, it is approximately one-third the depth of the chest – generally around 2 inches as well for many pediatric patients.

This recommendation reinforces the importance of delivering strong and effective compressions during CPR. Techniques that involve compressing to the appropriate depth are critical in increasing survival chances for patients in cardiac arrest.
