Advanced Cardiovascular Life Support (ACLS) Practice Exam

If an AED does not promptly analyze a rhythm, what is the next step to take?

1. Adjust the pads on the patient

2. Begin chest compressions

3. Check the patient's pulse

4. Switch to manual defibrillation

The correct answer is: Begin chest compressions

When an Automated External Defibrillator (AED) does not promptly analyze a rhythm, it is essential to maintain the quality of chest compressions, as this is critical for preserving circulation and oxygenation to vital organs during a cardiac arrest scenario. Chest compressions should be initiated immediately to provide effective blood flow and increase the chances of a successful rhythm analysis once the AED is ready. In the context of an unresponsive patient in need of defibrillation, ensuring that chest compressions are ongoing is vital. The rhythm can then be analyzed again after a brief period of uninterrupted CPR to determine if a shockable rhythm is present. Initiating compressions also allows for the proper functioning of the AED if it is able to continue analyzing rhythms during the compressions, as it may not function optimally if the patient is not receiving adequate compressions. This response underscores the importance of following current resuscitation guidelines, which prioritize high-quality CPR, especially when an AED is not able to provide immediate analysis.
