Basic Life Support (BLS) Practice Exam

Is it necessary to adjust AED pad placement if a patient has a pacemaker or ICD?

1. Yes, AED pads should be placed directly over the device

2. No, it does not matter

3. Yes, pads should not be placed directly over the device

4. No, only if it malfunctions

The correct answer is: Yes, pads should not be placed directly over the device

In the context of using an Automated External Defibrillator (AED) on a patient with a pacemaker or Implantable Cardioverter Defibrillator (ICD), it is crucial to ensure that the AED pads are placed correctly to avoid complications. Specifically, the pads should not be placed directly over the device. The reason for this is that placing the pads over a pacemaker or ICD can impede the effectiveness of the defibrillation. These devices are sensitive and designed to deliver electrical impulses to regulate the heart’s rhythm. If the AED's electrical shock is delivered directly over the device, it could interfere with its normal function or even cause injury to the patient. Instead, the pads should be positioned in accordance with the AED's instructions, ensuring they are placed on the chest in a manner that allows for effective shock delivery while avoiding the area where the pacemaker or ICD is located. This knowledge highlights the importance of being aware of the patient’s medical devices during resuscitation efforts, enabling responders to provide the safest and most effective care possible.
