What is the aim of performing CPR effectively and correctly?

Performing CPR effectively and correctly aims to restore blood circulation and breathing in an individual who has suffered a cardiac arrest or has stopped breathing. When a person's heart stops beating or they become unresponsive, immediate action is crucial to maintain blood flow to vital organs, especially the brain. CPR involves chest compressions to pump the heart and ventilations to provide oxygen to the lungs. This process helps to sustain life and can significantly increase the chances of survival until professional medical help arrives. The emphasis on restoring circulation and breathing highlights the life-saving intent of CPR, making it essential in emergencies where time is critical.
