What is the recommended compression depth for adult CPR?

The recommended compression depth for adult CPR is 2 inches to 2 1/2 inches. This depth is crucial because it ensures that enough pressure is applied to effectively compress the chest and create adequate circulation during cardiac arrest. Compressions at this depth can help to generate sufficient blood flow to vital organs, particularly the heart and brain, which are critical to survival.

Depths of less than 2 inches may not provide sufficient force to circulate blood effectively, potentially leading to a higher risk of a poor outcome for the patient. Additionally, compressions that are deeper than 2 1/2 inches can pose a risk of injury, such as rib fractures or damage to internal organs, while also risking a decrease in the effectiveness of compressions as rescuers may struggle to maintain proper technique.

This guideline aligns with recommendations from organizations like the American Heart Association, which emphasize the importance of achieving the right compression depth as part of effective CPR. It is essential for both laypersons and trained responders to understand and apply these depth guidelines to maximize the chances of survival in emergency situations.
