What should be done if an AED advises "no shock"?

When an AED advises "no shock," it indicates that the device has determined that the heart's rhythm does not require defibrillation. In this situation, continuing CPR and reassessing the patient is essential. This approach is critical because it helps maintain circulation to vital organs until advanced medical personnel arrive or the AED can provide further analysis.

Continuing CPR ensures that blood flow to the heart and brain is sustained, which is crucial for the patient's survivability. After a few cycles of CPR (typically every 2 minutes), the AED can again be checked to see if it recommends a shock or if any changes in the patient's condition have occurred. This process establishes a rhythm of ongoing assessment and intervention that is vital in emergency care.

Other options, like stopping CPR or switching to a different AED, would be counterproductive and could lead to an increased risk of negative outcomes for the patient, as maintaining circulation is crucial in a cardiac emergency.
