Free BLS Automated External Defibrillator (AED) Use Questions and Answers

Question 1

What is the first step when using an AED?

Accepted Answer

Turn on the AED

Answer

The very first step when using an Automated External Defibrillator (AED) is to turn it on. This activates the device, allowing it to provide voice prompts and instructions that guide the rescuer through the subsequent steps, such as applying pads and analyzing the heart rhythm. Following these prompts ensures correct and timely use.

Question 2

Where should AED pads be placed on an adult victim?

Accepted Answer

Upper right chest and lower left side

Answer

For an adult victim, AED pads should be placed on the upper right side of the chest, just below the collarbone, and on the lower left side of the chest, below the armpit. This placement ensures that the electrical current passes through the heart, maximizing the chances of successful defibrillation.

Question 3

What should you do if the AED advises a shock?

Accepted Answer

Deliver the shock immediately

Answer

If the AED advises a shock, the rescuer must ensure everyone is clear of the patient and then deliver the shock immediately. Delaying defibrillation significantly reduces the chances of survival for a victim in ventricular fibrillation. Following the AED's prompt is crucial for timely intervention.

Question 4

What is the correct action immediately after a shock is delivered?

Accepted Answer

Resume CPR

Answer

Immediately after a shock is delivered by an AED, the rescuer must resume chest compressions without delay. There should be no pause to check for a pulse or rhythm, as early resumption of compressions is critical to maintain blood flow to the brain and heart. The AED will re-analyze the rhythm after two minutes of CPR.

Question 5

Can AEDs be used on children under 8 years old?

Accepted Answer

Yes, with pediatric settings or pads

Answer

AEDs can indeed be used on children under 8 years old, but it's crucial to use appropriate equipment. Pediatric pads or a pediatric attenuator are specifically designed to deliver a lower, safer dose of electrical energy suitable for a child's smaller body. Using these specialized settings ensures effective defibrillation while minimizing the risk of delivering an excessive shock.
