What does "rescue breathing" refer to?

Rescue breathing refers to the method of providing artificial ventilation to a person who is unresponsive and not breathing, or has no pulse. This technique is crucial because it involves delivering breaths to the victim, allowing oxygen to enter their lungs and circulate through their body, which can help sustain vital organs until professional medical help arrives or the person regains the ability to breathe on their own.

It is an essential skill taught in lifesaving courses, as it plays a key role in the chain of survival during cardiac arrest or near-drowning scenarios. Understanding how to effectively perform rescue breathing can significantly improve the chances of survival in emergency situations where a person is not breathing.

The other options involve different aspects of first aid and emergency response but do not accurately describe the specific process of rescue breathing.
