What is the appropriate compression depth for CPR in adults?

The appropriate compression depth for CPR in adults is between 5 to 6 centimeters. This depth is recommended to ensure enough force is applied to effectively compress the chest cavity, allowing for adequate blood flow during the compressions. Compressions that are too shallow may not circulate blood effectively, while those that are too deep can potentially cause injuries such as rib fractures or damage to internal organs.

The guideline of 5 to 6 centimeters is based on research highlighting that this depth maximizes perfusion pressure and improves the chances of resuscitation. This standardization aims to provide a consistent and effective approach to CPR, which is crucial in emergency situations where immediate action is necessary to preserve life.
