What is the recommended compression depth for adults during CPR?

The recommended compression depth for adults during CPR is 2 inches (approximately 5 cm). This depth is crucial to ensure that adequate pressure is applied to the chest in order to effectively compress the heart and maintain blood circulation. When compressions are performed at this depth, they can help create sufficient blood flow to vital organs, particularly the brain and heart, increasing the chances of survival during a cardiac arrest.

Compressing deeper than the recommended 2 inches can lead to complications, such as injury to the ribs or damage to internal organs, while compressing less than this may not provide enough blood flow and can significantly reduce the efficacy of the resuscitation efforts. This 2-inch guideline aligns with current CPR guidelines developed by leading organizations in emergency medical care, ensuring that responders provide high-quality CPR that maximizes patient outcomes.
