How deep should chest compressions be on an adult?

The recommended depth for chest compressions in an adult during cardiopulmonary resuscitation (CPR) is within the range of 5 to 6 centimeters. This depth is critical because adequate force is necessary to create sufficient blood flow to vital organs, particularly the brain and heart, during cardiac arrest. Compressions that are too shallow may not be effective in generating enough pressure to circulate blood, while compressions that are too deep can risk causing injuries to the ribs and organs.

Achieving the correct compression depth is essential for the effectiveness of resuscitation efforts. The American Heart Association and other resuscitation guidelines emphasize this depth not only to maximize the chances of survival but also to minimize potential harm. Following these guidelines increases the likelihood of positive outcomes in cardiac arrest situations.
