Question

What are the contraindications for using an AED (Automated External Defibrillator) in a cardiac arrest scenario?

a) Patient submerged in water
b) Patient's chest covered in sweat
c) Patient with a metal implant in the chest
d) Patient with a known history of heart disease

Answer 1

Automated external defibrillators (AEDs) have certain contraindications when used in a cardiac arrest scenario. These include a patient submerged in water, a patient with a chest covered in sweat, a patient with a metal implant in the chest, and a patient with a known history of heart disease.

Step-by-step explanation:

Automated External Defibrillators (AEDs) are important devices used in cardiac arrest scenarios to deliver a shock to the heart in order to restore a normal rhythm. However, there are certain contraindications for using an AED:

1. Patient submerged in water: Using an AED on a patient who is submerged in water can be dangerous as it may cause electrical shock to anyone in contact with the patient or the water.
2. Patient's chest covered in sweat: Sweat can create a barrier between the AED electrodes and the patient's skin, preventing proper electrical contact and reducing the effectiveness of the shock.
3. Patient with a metal implant in the chest: The presence of a metal implant in the chest can interfere with the delivery and effectiveness of the shock, potentially causing harm to the patient.
4. Patient with a known history of heart disease: AEDs should not be used on patients with a known history of heart disease without proper medical guidance, as their condition may require specialized treatment.
