In cases of cardiac arrest, what is the first action that should be taken?

In cases of cardiac arrest, the first action that should be taken is to call for help and activate emergency response. This step is crucial because it ensures that professional medical services are on their way, which significantly increases the chances of survival for the patient. Immediate access to advanced medical care can include defibrillation, advanced airway management, and administration of necessary medications, all of which can be critical in effectively managing a cardiac arrest situation.

By activating the emergency response system, you are not only summoning additional help but also allowing for early intervention that can save a life. Following this, starting chest compressions is vital, but it should come after ensuring that emergency services are alerted and on their way. The protocol emphasizes the importance of early notification of emergency medical services in parallel with life-saving actions.
