What is the ideal chest compression depth for adult CPR?

The ideal chest compression depth for adult CPR is between 2 to 2.5 inches. This depth is crucial for effectively generating blood flow during chest compressions. Compressions performed at this depth will help create sufficient pressure to circulate blood effectively to vital organs, particularly the brain and heart.

This guideline is rooted in research demonstrating that compressions within this range optimize the chances of maintaining circulation during cardiac arrest. The recommended depth ensures that the heart is adequately compressed and can generate enough pressure to push blood through the arteries, thus enabling better oxygen delivery to tissues.

Maintaining the correct depth is vital in achieving effective CPR, as shallower compressions may not create enough pressure to circulate blood effectively, which could reduce the likelihood of survival. It's essential that CPR providers focus on both compression depth and rate to maximize the impact of their efforts in a cardiac emergency.
