What is the appropriate depth for chest compressions during adult CPR?

The appropriate depth for chest compressions during adult CPR is 2 to 2.5 inches. This depth is important as it ensures adequate compression of the heart, facilitating effective blood circulation during cardiopulmonary resuscitation. The guideline helps to create sufficient pressure in the thoracic cavity, which is necessary to maintain blood flow to vital organs, particularly the brain and heart. Compressing too shallowly may not generate enough pressure to circulate blood effectively, while compressing too deeply could risk causing injury to the ribs or internal organs. Following the recommended depth supports the overarching goal of improving patient outcomes in cardiac arrest scenarios.
