Question 1

What is the main advantage of a biphasic waveform AED over older monophasic devices?

Accepted Answer

It is more effective at lower energy levels, reducing myocardial damage

Answer

Biphasic AEDs are as effective or more effective at lower energies than monophasic devices, causing less myocardial damage.

Question 2

When should pediatric AED electrode pads or attenuation keys be used?

Accepted Answer

For children aged 1-8 years (or under 25 kg) when available

Answer

Pediatric pads or attenuation keys should be used for children under 8 years or under 25 kg when available, as they reduce delivered energy to safe levels.

Question 3

What is the correct anteroposterior (front-to-back) electrode pad placement for AED use?

Accepted Answer

One pad on the front center of the chest, one pad on the back between the shoulder blades

Answer

Anteroposterior placement puts one pad on the front center of the chest and one on the back, which is used in special situations like a pacemaker or breast tissue.

Question 4

What should be done if a patient has a hairy chest when applying AED electrode pads?

Accepted Answer

Firmly press and rip off the first set of pads to remove hair, then apply a new set

Answer

Pressing and removing the first set of pads removes chest hair, allowing the second set to adhere properly and deliver current effectively.

Question 5

What is the significance of an AED's rhythm analysis algorithm in the context of shock delivery?

Accepted Answer

It detects VF and pVT patterns and advises shock, while detecting non-shockable rhythms and advising no shock

Answer

AED algorithms analyze the ECG signal to identify shockable (VF/pVT) vs. non-shockable (asystole/PEA) rhythms and advise the rescuer accordingly.
