What is the purpose of chest compressions in CPR?

The purpose of chest compressions in CPR is to maintain blood circulation. When a person's heart stops beating effectively, blood flow to vital organs, including the brain, is compromised. Chest compressions generate pressure in the chest cavity, which helps pump blood through the heart and into the rest of the body. This process is crucial because it helps sustain organ function and increases the chances of survival until advanced medical help arrives. By ensuring continued circulation, chest compressions seek to preserve brain activity and bodily functions, providing essential support during cardiac arrest.
