Which is a potential outcome if CPR is not performed promptly?

In situations where CPR is not performed promptly, one of the most serious potential outcomes is irreversible brain damage. When a person's heart stops beating, blood flow to the brain is interrupted. The brain cells are highly sensitive to a lack of oxygen, and within just a few minutes of the heart stopping, significant damage can occur. If CPR is initiated quickly, it can help restore blood flow and oxygen to the brain, drastically improving the chances of survival and reducing the risk of lasting neurological damage.

This outcome underscores the critical importance of immediate action in the event of a cardiac arrest. Without prompt CPR, the likelihood of severe brain injury increases substantially, making it essential for bystanders to recognize the signs of cardiac arrest and act quickly.
