In the context of resuscitation, what does "effective ventilation" help to restore?

Effective ventilation is crucial during resuscitation as it directly impacts the oxygen supply to vital organs, particularly the brain. When a person experiences a cardiac arrest or respiratory failure, the body’s ability to take in oxygen and expel carbon dioxide is compromised. Through effective ventilation, which includes techniques like mouth-to-mouth and bag-mask ventilation, the goal is to ensure that adequate oxygen is delivered into the lungs and, consequently, into the bloodstream.

When oxygen is supplied effectively through ventilation, it allows for an adequate amount of oxygen to reach the brain, which is vital for maintaining brain function and preventing permanent damage. The brain is highly sensitive to a lack of oxygen, and even a few minutes without adequate oxygen can lead to irreversible consequences. Therefore, effective ventilation plays a critical role in restoring oxygen supply to the brain, supporting the continuation of brain activity and function during the resuscitation process.
