How frequently do people in cardiac arrest lose their chances of survival?

People in cardiac arrest lose their chances of survival every minute due to the critical need for immediate intervention. The first few minutes after cardiac arrest are crucial; brain damage can occur within 4 to 6 minutes without oxygen-rich blood, and the likelihood of survival decreases significantly as time passes. The American Heart Association emphasizes the importance of CPR and defibrillation during the first minutes following cardiac arrest, and research indicates that for each minute without intervention, survival rates decrease by approximately 7-10%. This urgent timeline underscores the necessity of rapid response to enhance the chances of survival. The other options suggest longer intervals, which do not reflect the immediate danger posed by delayed care in the event of a cardiac arrest emergency.
