What is the proper depth for chest compressions in adults?

The proper depth for chest compressions in adults is indeed between 2 to 2.4 inches. This depth is crucial because it allows for effective circulation during cardiopulmonary resuscitation (CPR). When compressions are delivered at the correct depth, they are more likely to create sufficient pressure to circulate blood and oxygen to vital organs, which can significantly increase the chances of survival in a cardiac arrest situation.

Compression depth is based on guidelines from organizations such as the American Heart Association, which emphasizes that compressions should be hard and fast, at a rate of 100 to 120 compressions per minute, and should reach a depth of at least 2 inches, without exceeding 2.4 inches. Compressions that are too shallow may fail to adequately circulate blood flow, while excessively deep compressions can potentially cause injury to the ribs or internal organs, highlighting the importance of adhering to the recommended depth range.
