What happens to survival rate with every 60 seconds delay between cardiac arrest and CPR?

The correct answer indicates that for every minute, or specifically every 60 seconds, delay in initiating CPR (cardiopulmonary resuscitation) after a cardiac arrest, the chances of survival decrease significantly. The statistical evidence suggests that the survival rate decreases by approximately 10% with each passing minute. This decline is critical because brain death can occur within minutes without oxygen, and timely intervention is essential for improving outcomes for cardiac arrest victims.

Understanding this relationship emphasizes the importance of immediate action in emergency situations, advocating for the swift provision of CPR to maintain blood flow and oxygen supply to vital organs until professional medical help arrives. This decrease in survival rate highlights the need for public training in CPR and awareness about the urgency of the situation, as well as the value of calling emergency services promptly.
