For every 1 minute delay in CPR and defibrillation, the chance of survival is reduced by what percentage?

The correct answer highlights a critical aspect of emergency response during a cardiac arrest scenario: the importance of time in the effectiveness of CPR and defibrillation. Research indicates that for every minute that passes without CPR and defibrillation after a cardiac arrest, the chances of survival decrease by approximately 7% to 10%. This statistic underscores the urgent need for prompt initiation of life-saving measures.

Providing immediate CPR helps to maintain blood circulation and oxygenation to vital organs, particularly the brain, which is highly susceptible to damage from lack of oxygen. Similarly, defibrillation is crucial in restoring a normal heart rhythm. The longer these life-saving interventions are delayed, the more significant the decline in a patient's chances of survival.

Thus, understanding this time-sensitive nature of cardiac arrest care can motivate healthcare providers to act quickly and efficiently in emergencies, ultimately improving patient outcomes.
