During adult CPR, to what depth should the chest be compressed?

In adult CPR, chest compressions should be delivered to a depth of 2 inches. This depth is crucial because it ensures that enough pressure is applied to effectively compress the heart and facilitate blood circulation during cardiac arrest. Compressions that are too shallow may not generate adequate blood flow to vital organs, particularly the brain and heart, which are most susceptible to damage during a lack of oxygen.

Additionally, compressions performed at this depth also help maintain a consistent and effective rhythm while keeping a balance between the rate of compressions and the depth. Maintaining a depth of 2 inches aligns with the current guidelines provided by organizations such as the American Heart Association, ensuring that rescuers can deliver optimal care to victims of cardiac arrest.
