What is the correct CPR compression depth for adults?

The correct compression depth for adult CPR is approximately 2 inches. This guideline is based on the recommendations from leading health organizations such as the American Heart Association (AHA) and the European Resuscitation Council (ERC).

When performing CPR, achieving an adequate depth of chest compressions is crucial for effectively restoring circulation and increasing the chances of survival in a cardiac arrest situation. Compressions that are too shallow may fail to circulate enough blood to vital organs, while compressions that are too deep could potentially cause injury to the chest cavity or organs.

In adults, the recommended depth of about 2 inches strikes the right balance, allowing for sufficient pressure to ensure blood flow without risking harm. This depth applies to adult victims of varying body sizes, as the ribcage is robust enough to accommodate this level of compression. It is also recommended that CPR is performed at a rate of 100 to 120 compressions per minute, maintaining this depth to maximize effectiveness in an emergency situation.
