What is the correct depth for chest compressions during CPR?

Explanation:
The depth of chest compressions should be enough to squeeze the heart and push blood out, but not so deep that it causes injury. The correct target is about one third to one half the depth of the chest. In adults, this usually translates to roughly 5 cm (about 2 inches). Pressing deeper than this isn’t necessary and can increase the risk of injury, while pressing too shallowly won’t move enough blood to sustain circulation. So that middle range is the balance that makes compressions effective while staying as safe as possible.
