What is the recommended depth for chest compressions in adults?

The recommended depth for chest compressions in adults is at least 2 inches. This guideline is based on research and best practices established by organizations such as the American Heart Association and the Canadian Red Cross. The reason for the depth of 2 inches is to ensure that compressions are adequate enough to create sufficient blood flow during a cardiac arrest scenario. Compressions that are too shallow may not generate the necessary pressure to effectively circulate blood, which is crucial for survival until advanced medical help arrives.

Ultimately, compressing the chest to a depth of at least 2 inches provides a balance between effectiveness and the risk of injury to the individual receiving help. This standard helps responders be more confident in the quality of compressions they are performing, thereby increasing the chances of a positive outcome in a cardiac arrest situation.
