Which of these best describes the purpose of "hands-only" CPR?

The purpose of "hands-only" CPR (Cardiopulmonary Resuscitation) is to provide immediate, effective chest compressions to a person who has suffered a cardiac arrest, without the need for mouth-to-mouth breaths. This technique focuses solely on the compression of the chest, which helps maintain blood flow to vital organs by manually pumping the heart.

"Hands-only" CPR is recommended because it is easier for bystanders to perform in emergency situations, especially for those who may not be trained in traditional CPR methods that include rescue breaths. The goal is to maximize the chances of preserving brain function and increasing survival rates until professional medical help arrives. It is essential to start CPR as quickly as possible, as every minute counts in a cardiac emergency.
