What is the purpose of giving breaths during CPR?

The primary purpose of giving breaths during CPR is to provide oxygen to the lungs. When an individual is unresponsive and not breathing normally, their body is deprived of oxygen which can lead to brain damage and other organ dysfunctions very quickly. By delivering artificial breaths, you are ensuring that oxygen is introduced into the lungs, allowing it to enter the bloodstream and ultimately reach vital organs.

While circulation and heart stimulation are also critical factors in CPR, those are primarily addressed through chest compressions, which help maintain blood flow to vital organs. The nutrient delivery and heart stimulation options do not accurately reflect the specific physiological need addressed by rescue breaths, which is about oxygenation in particular. Hence, providing breaths is crucial for maintaining adequate oxygen levels until advanced medical help arrives.
