What is the correct sequence of the initial treatment for a patient in cardiac arrest?

The correct sequence of initial treatment for a patient in cardiac arrest emphasizes the critical importance of starting high-quality CPR as quickly as possible. In the chosen option, initiating CPR immediately while simultaneously attaching an Automated External Defibrillator (AED) ensures that the patient receives timely chest compressions, which are vital for maintaining blood circulation and oxygenation.

Once the AED is attached, it can analyze the heart rhythm to determine if a shock is advised. If a shock is indicated, the prompt delivery of that shock can potentially restore a normal rhythm. After delivering the shock, resuming CPR for two minutes is essential, as continuing circulation and oxygenation increases the chances of survival until advanced help arrives. Checking for a pulse afterwards allows the responder to assess the effectiveness of the interventions performed and decide on the next steps.

This sequence follows established guidelines such as those from the American Heart Association, which prioritize starting CPR and using the AED early to optimize the chances of survival in cases of cardiac arrest.
