When is it necessary for an EMT to use an AED?

• A. When a patient is breathing normally
• B. When a patient is responsive and alert
• C. When a patient is unresponsive and not breathing normally
• D. When a patient shows signs of a stroke

Answer: (C)

The scenario in which an EMT should employ an Automated External Defibrillator (AED) is when a patient is unresponsive and not breathing normally. This specific situation typically indicates that the patient may be experiencing a cardiac arrest or some severe arrhythmia, which can deprive the body of oxygen-rich blood. The primary purpose of an AED is to analyze the heart's rhythm and provide defibrillation if needed to restore a normal heartbeat. In instances when a patient is breathing normally or is responsive and alert, there’s no immediate need for an AED, as these patients do not show signs of cardiac arrest. Similarly, recognizing signs of a stroke requires a different approach that focuses on immediate medical intervention and transport; the use of an AED is not relevant in those circumstances. Thus, the correct and crucial scenario for using an AED is when the patient is unresponsive and not breathing normally, signaling a life-threatening emergency where time is critical.
