What is the minimum recommended depth for chest compressions in adults during CPR?

The minimum recommended depth for chest compressions in adults during CPR is 2 inches. This depth is crucial because effective compressions must generate sufficient pressure to circulate blood throughout the body, particularly to the brain and vital organs. Compressions that are too shallow may not adequately perfuse the heart and brain, diminishing the chances of survival after cardiac arrest. The depth of 2 inches strikes a balance between being deep enough to create effective blood flow, while still being manageable for rescuers to perform without risking injury to themselves or the patient. This recommendation is based on extensive research and guidelines issued by organizations like the American Heart Association, which seek to standardize CPR techniques to improve outcomes for individuals experiencing cardiac emergencies.
