If a patient is apneic without a pulse, what should you call for?

• A. AED
• B. Ventilator
• C. Oxygen Mask
• D. Defibrillator

Answer: (A)

In a pulseless, apneic patient, the priority is to restore a perfusing rhythm as quickly as possible. The quickest and most effective way to do that is defibrillation when the rhythm is shockable. An automated external defibrillator is designed for bystanders to use and will analyze the heart rhythm and deliver a shock if needed, making it the device you call for in this situation. While you wait for the AED, start high-quality CPR to maintain blood flow. A ventilator or oxygen mask won’t address the need to restart the heartbeat, and a defibrillator (while related) is specifically the tool you call for first in this scenario because it provides the defibrillation capability you need immediately.
