What is the recommended compression depth for adults during CPR?

The recommended compression depth for adults during CPR is at least 2 inches. This depth is crucial for generating enough pressure to effectively circulate blood and oxygen to vital organs, particularly the brain and heart, during a cardiac arrest situation. Research and guidelines from organizations such as the American Heart Association emphasize that compressions should be deep enough to ensure adequate blood flow.

Using a compression depth of at least 2 inches helps to create sufficient intrathoracic pressure, which is necessary for perfusing the body's vital organs. If the compression depth is too shallow, as seen with depths less than 2 inches, there might not be enough pressure generated to maintain effective circulation. Moreover, compressions that exceed the recommended depth of 2.4 inches can increase the risk of injury to the ribs and internal organs without providing additional benefits to blood flow, making the recommended depth a balance between effectiveness and safety.
