Which chest compression depth is recommended for high-quality CPR on adults?

The recommended chest compression depth for high-quality CPR on adults is 2 inches. This depth is critical because compressions at this level ensure adequate blood flow to the heart and brain during cardiac arrest. Compressions that are too shallow may not generate sufficient pressure to circulate blood effectively, which can lead to decreased chances of survival and increased risk of brain injury due to lack of oxygen.

Chest compressions should be performed at a rate of 100 to 120 compressions per minute and allow for complete chest recoil after each compression. This combination of depth and rate maximizes the effectiveness of CPR, improving the likelihood of a successful resuscitation.

The recommended depth is based on guidelines set by organizations such as the American Heart Association, which emphasize the importance of proper technique in optimizing outcomes for cardiac arrest patients.
