What is the purpose of rescue breaths in CPR?

The purpose of rescue breaths in CPR is to provide oxygen to the victim’s lungs. When someone is unresponsive and not breathing, their body is deprived of the vital oxygen needed for survival. Administering rescue breaths helps to deliver oxygen directly into the lungs, ensuring that oxygen enters the bloodstream and reaches the brain and other vital organs. This is especially important because, during a cardiac arrest, blood circulation has stopped, and without immediate oxygenation, the chances of irreversible damage to the brain and other organs increase dramatically.

While other choices may relate to different aspects of first aid or emergency response, they do not accurately capture the primary function of rescue breaths during CPR. The key focus is on restoring vital oxygen levels to sustain life until further medical assistance can be provided.
