In adult CPR, how deep should chest compressions be performed?

Chest compressions in adult CPR should be performed at a depth of at least 2 inches to be most effective. This depth allows for adequate blood flow to the heart and brain during the critical moments of cardiac arrest. The compression depth is essential because it ensures that the heart is compressed effectively, which facilitates blood circulation.

Performing compressions at this depth helps to create the necessary pressure needed to push blood out of the heart and into the vital organs. It is also important that the compressions are delivered at a rate of 100 to 120 compressions per minute, with a complete release between compressions to allow the heart to fill with blood again.

Depths less than 2 inches may not provide sufficient blood flow, diminishing the chances of survival in a cardiac arrest scenario. Therefore, adhering to this guideline is crucial for maximizing the effectiveness of CPR.
