What is the recommended depth of chest compressions during adult CPR?

The recommended depth of chest compressions during adult CPR is at least 2 inches. This depth is based on guidelines from organizations such as the American Heart Association and the Resuscitation Council, which emphasize that deep compressions are crucial for generating adequate blood flow during cardiac arrest. A depth of 2 inches is important because it allows for sufficient compression of the heart and facilitates effective pumping of blood to vital organs, which can increase the chances of survival.

Compressions that are too shallow may not adequately circulate blood, which is why greater depths are preferred. Staying within this 2 to 2.4-inch range ensures that chest compressions are not only effective but also within a range that is generally safe for an adult's thoracic structure.
