AED Advanced Flashcards

A bystander reports the patient collapsed near a gasoline spill. What is the priority before AED use?

Answer: Move the patient to a safe area away from flammable vapors

An AED spark can ignite flammable fumes, so relocate the patient to a safe spot first.

How frequently should AEDs in a public access program typically undergo readiness checks?

Answer: Routinely (e.g., monthly) plus automatic self-tests

Regular checks and built-in self-tests ensure the AED is functional when needed.

What does the green check or 'ready' status indicator on most AEDs signify?

Answer: The device has passed self-tests and is ready for use

A ready indicator confirms the AED's self-test passed and the unit is operational.

AED pads have an expiration date. Why does this matter?

Answer: The conductive gel can dry out, reducing shock effectiveness

Over time the gel degrades and adhesion weakens, so expired pads should be replaced.

A lone rescuer witnesses an adult collapse and an AED is within reach. What is the recommended priority?

Answer: Retrieve and apply the AED as quickly as possible

For a witnessed adult arrest, early defibrillation is critical, so get the AED right away.

The AED prompts to 'connect pads' but they are already attached. What is the likely cause?

Answer: Poor pad contact or a loose connector that needs to be reseated

This prompt usually signals inadequate skin contact or a disconnected cable, so press the pads down and check the connector.

Why should rescuers avoid placing AED pads over the breastbone's center (sternum) on the heart's electrical path incorrectly?

Answer: Proper anterior-lateral placement directs current through the heart

Correct placement—upper right chest and lower left side—routes the shock across the heart for maximum effect.
