What is the correct compression depth for adults during CPR?

The recommended compression depth for adults during CPR is 2 to 2.4 inches. This depth is crucial because it is designed to effectively circulate blood during cardiac arrest, ensuring that vital organs receive sufficient oxygenated blood. Compressions that are too shallow may not generate enough pressure to be effective, while compressions that are too deep can potentially injure the ribcage and internal organs. The guidelines emphasize finding that balance, hence the recommendation falls within the 2 to 2.4 inches range, allowing for optimal blood flow while minimizing injury risk. Adhering to these depth guidelines during CPR is essential for maximizing the chances of survival in a cardiac emergency.
