If using an AED in auto mode and no shock is advised, what should you do next?

When using an AED in auto mode and it indicates that no shock is advised, the next step is to continue CPR, starting with chest compressions. This approach is based on the understanding that when a shock is not indicated, the patient's heart is not in a rhythm that can be corrected with an electric shock, and effective chest compressions are critical for maintaining blood flow to vital organs.

Continuing CPR ensures that circulation is maintained while waiting for further medical intervention. Resuming with chest compressions immediately after the AED indicates no shock helps to maximize the chance of survival by promoting blood flow, which is essential until the heart can return to a normal rhythm or until emergency medical services arrive.

The other options are less effective in this scenario. Pausing CPR to reassess the victim or changing the AED pads would interrupt vital compressions, which is not recommended during cardiac arrest. Waiting for further instructions from the AED will stall progress because time is crucial in these situations. Therefore, immediate continuation of CPR is the best course of action.
