What is the depth of compressions in CPR?

Explanation:
Two inches (about 5 cm) is the recommended depth for chest compressions in adult CPR. This depth provides enough pressure to move blood through the heart and into the circulation with each compression, while still allowing the chest to recoil fully between pushes. Compressing shallower than this reduces blood flow and makes CPR less effective, whereas excessively deep compressions can increase injury risk without added benefit. Aim for about 2 inches, keep a steady pace of 100–120 compressions per minute, and ensure complete chest recoil between compressions.
