The purpose of "hands-only" CPR is to provide continuous chest compressions without rescue breaths in order to keep blood pumping through the victim's body until paramedics arrive with advanced care. It is designed for bystanders who may be untrained or uncomfortable with mouth-to-mouth resuscitation and aims to maintain circulation to vital organs, especially the brain, during the first few critical minutes of a cardiac arrest. This method is simpler, faster to learn, and helps increase the person's chances of survival significantly by ensuring uninterrupted blood flow until professional help arrives.
