Final answer:
Early CPR helps keep oxygen-rich blood flowing to vital organs.
Step-by-step explanation:
Early CPR helps keep oxygen-rich blood flowing to vital organs. When the heart stops, CPR can maintain the flow of blood until the heart resumes beating. By applying pressure to the sternum, the blood within the heart is squeezed out into the circulation. This is critical in preventing irreversible damage and death of neurons in the brain.
