During transport, if a patient with severe chest pain becomes unresponsive and pulseless, what is the recommended action?

• A. Stop the ambulance, call for help, and manage the airway
• B. Stop the ambulance, begin CPR, and attach the AED as soon as possible
• C. Call for medical control
• D. Wait for paramedics to arrive

Answer: (B)

When a patient with chest pain becomes unresponsive and pulseless, you’re dealing with cardiac arrest. The most important actions are immediate, high-quality chest compressions and rapid defibrillation with an AED. Start CPR right away, delivering compressions at a steady rate (about 100–120 per minute) with full chest recoil and minimal interruptions. As soon as the AED is available, turn it on and apply pads; follow its prompts. If the device advises a shock, deliver it, then resume CPR immediately for about two minutes before the next analysis.

Airway management and ventilation are important, but they should not delay chest compressions and defibrillation. Do not wait to call for help or to wait for others to arrive—the critical time is now, and continuing CPR with prompt defibrillation offers the best chance of survival.
