What is the recommended depth of chest compressions for an adult?

The recommended depth of chest compressions for an adult is indeed between 2 to 2.5 inches. This depth is important because it allows for the effective compression of the heart, which is located behind the sternum. Correct depth ensures adequate blood flow to vital organs during cardiopulmonary resuscitation (CPR), maximizing the chances of survival in a cardiac emergency.

Compressions that are too shallow may not create sufficient pressure to circulate blood effectively, while compressions that are too deep can potentially cause injury to the ribs or internal organs. The guidelines emphasize the need for compressions to be at least 2 inches deep to achieve the best outcomes, which is why this range is considered the standard for adult CPR.

Understanding this optimal range is crucial for anyone involved in first aid and emergency response, especially for professional divers who may encounter cardiac emergencies either in or out of the water.
