Why is it important to call for help as soon as cardiac arrest is suspected?

It is crucial to call for help as soon as cardiac arrest is suspected because doing so ensures that advanced medical assistance can arrive in a timely manner. Cardiac arrest is a life-threatening situation that requires immediate action. While initiating CPR is vital for sustaining life during the critically short window before professional help arrives, activating emergency services immediately allows for the quickest possible response from paramedics or emergency medical technicians. These professionals can provide advanced interventions such as defibrillation and medication that are essential for increasing the chances of survival.

This answer emphasizes the importance of early intervention from healthcare professionals, as their expertise and equipment can significantly impact the outcome for the victim. Delaying the call for help can negatively affect survival rates, so making that call promptly is a foundational step in the chain of survival in cardiac emergencies.
