What is the recommended compression depth for adults during CPR?

The recommended compression depth for adults during CPR is at least 2 inches (5 cm). This depth is crucial because it ensures that enough pressure is applied to effectively compress the chest and facilitate adequate blood flow to vital organs during cardiac arrest.

The goal of compressions is to create sufficient intrathoracic pressure to force blood out of the heart and into circulation. Research and guidelines have determined that a compression depth of at least 2 inches strikes a balance between effectiveness and safety for adult patients. Compressions that are too shallow may not create adequate blood flow, compromising the chances of survival and recovery.

Moreover, compressions should be performed at a rate of 100 to 120 compressions per minute, combined with proper technique to maintain the effectiveness of each compression. The focus should always be on delivering high-quality CPR, which includes ensuring the correct depth and allowing for full chest recoil between compressions.
