How long does the AED wait before analyzing again after a shock is delivered?

• A. 1 minute
• B. 2 minutes
• C. 3 minutes
• D. 5 minutes

Answer: (B)

After an AED delivers a shock, it typically waits for 2 minutes before analyzing the heart rhythm again. This duration is designed to allow the heart an opportunity to stabilize and potentially return to a normal rhythm following the shock. The AED will prompt for chest compressions to continue during this time in order to maintain blood flow to vital organs, maximizing the chance of a successful heart rhythm return. Ensuring that there is an adequate interval for analysis is crucial, as it allows the device to assess the efficacy of the shock and determine the next steps in resuscitation.
