How deep should you compress an adult's chest during CPR?

When performing CPR on adults, the recommended depth of chest compressions is at least 2 inches. This depth is crucial because compressions that are too shallow may not generate sufficient pressure to effectively circulate blood and oxygen throughout the body. The primary goal during CPR is to mimic the heart's pumping action and ensure that vital organs receive necessary blood flow. Research and guidelines from organizations such as the American Heart Association support this 2-inch depth as optimal for generating adequate blood flow to the heart and brain during cardiopulmonary resuscitation. Additionally, the compressions should be delivered at a rate of 100 to 120 compressions per minute, emphasizing the importance of both depth and speed in delivering effective CPR.
