Cardiopulmonary resuscitation, commonly known as CPR, is perhaps the most widely recognised intervention. It significantly increases a person’s likelihood of surviving a cardiac arrest, more than doubling their chances. CPR involves a combination of mouth-to-mouth ventilation and chest     compressions. It is administered when a person is unresponsive indicating no breathing, movement, or pulse. Interestingly, when administering CPR, the goal is not to directly restart the heart but rather to ensure continuous delivery of oxygenated blood to the brain and organs. Mouth-to-mouth ventilation supplies oxygen to the lungs, while chest compressions simulate the heart’s natural pumping action, sustaining blood circulation throughout the body. This vital procedure can sustain life until further assistance, such as arrival of emergency medical services or a medical professional, and significantly improves the chances of a successful recovery once the heart is revived.
