How much do the chances of survival decrease for every minute CPR is delayed?

The correct answer reflects a widely accepted guideline in emergency medicine regarding the effectiveness of cardiopulmonary resuscitation (CPR). Research indicates that for every minute that CPR is delayed, the likelihood of survival decreases by approximately 7-10%. This decline is attributed to the critical nature of maintaining blood flow and oxygenation to the brain and vital organs during cardiac arrest; without timely intervention, the chances of successful resuscitation and favorable outcomes diminish significantly.

This information is vital for first responders and bystanders alike, as it underscores the urgency of initiating CPR as soon as possible after a cardiac arrest occurs. Understanding the impact of time on survival can motivate quicker action in emergency situations, ultimately improving survival rates and recovery outcomes for individuals in distress.
