Cardiopulmonary Resuscitation (CPR) Practice 2026 – Comprehensive All-in-One Guide to Master Your CPR Skills!

The recommended compression depth for adult CPR is at least 2 inches. This depth is critical to ensure that sufficient pressure is applied to the chest to generate adequate blood flow to the heart and brain during cardiopulmonary resuscitation. Studies have shown that compressions of this depth are more effective in maintaining circulation compared to shallower compressions.

Compressing to a depth of 2 inches allows for better perfusion and increases the chances of survival in a cardiac arrest situation. It is also important to allow full chest recoil after each compression to facilitate adequate venous return. Maintaining this depth helps enhance the efficiency of compressions, maximizing the chances of successful resuscitation.

The other options are not sufficient depth to produce effective circulation during CPR. For adult patients, compressions shallower than 2 inches may not generate enough pressure in the thoracic cavity to effectively support blood circulation. This is why adherence to the 2-inch guideline is essential in CPR practice.
