What is the primary objective of providing ventilations during CPR?

The primary objective of providing ventilations during CPR is to provide oxygen to the lungs. When a person is in cardiac arrest, their heart is no longer effectively pumping blood, which means that oxygen is not being distributed to vital organs, including the brain. Administering ventilations ensures that oxygen reaches the lungs, allowing it to enter the bloodstream. This is crucial because it helps maintain some level of oxygenation in the body, which is essential for the survival of tissues and organs until more definitive medical help can restore normal heart function.

In the context of CPR, while other actions like chest compressions help circulate blood, the specific role of ventilations is to address the need for oxygen, making it the priority in situations where breathing has stopped.
