What is the correct depth for chest compressions in adult CPR?

The correct depth for chest compressions in adult CPR is about 2 inches. This guideline is based on extensive research and is established to ensure effective circulation during cardiopulmonary resuscitation. Compressions that are too shallow may not adequately perfuse vital organs, particularly the heart and brain, which rely on blood flow to sustain life.

The recommended compression depth allows for optimal blood return to the heart between compressions, enhancing the chances of maintaining perfusion during cardiac arrest. By compressing to a depth of at least 2 inches, the EMT can create a sufficient pressure gradient that increases blood flow to essential organs. Maintaining the correct depth also helps in producing an effective pump function of the heart, which is crucial during resuscitation efforts.

Using the proper depth, along with appropriate compression rate and allowing full chest recoil, are critical components of high-quality CPR, which can significantly improve survival outcomes in cardiac arrest cases. Emphasizing the importance of this depth is essential for training and practice in emergency medical situations.
