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

The recommended depth of chest compressions during CPR for adults is at least 2 inches (5 cm). This depth is crucial because compressions of this magnitude are more effective in generating adequate blood flow during cardiac arrest, which is essential for maximizing the chances of survival. Research has shown that compressions of less than 2 inches can significantly reduce the effectiveness of CPR by not providing enough pressure to circulate blood effectively.

By compressing to this recommended depth, you also ensure that the compressions are sufficiently strong and can maintain the necessary blood pressure to perfuse vital organs, especially the heart and brain, during the emergency. Effective CPR must be continuous and allows for blood flow to reach critical areas until advanced medical help arrives.
