What should not be done when using an AED?

When using an AED, it is crucial to allow the device to analyze the heart rhythm without any interference. Performing CPR while the AED is analyzing can disrupt this process. The AED requires a quiet environment to assess the heart's condition accurately and determine if a shock is needed. Interrupting this analysis by continuing chest compressions places the patient at risk, as the machine may misinterpret the rhythm or fail to deliver a shock if necessary.

Correct pad placement ensures good contact with the patient's chest, keeping the area dry minimizes the risk of shock delivery issues, and removing medication patches ensures that there is no interference with the AED's functioning or additional issues that could arise from burning or disrupting medication delivery. Each of these actions supports the AED's effectiveness, but performing CPR during its analysis can hinder the life-saving capabilities of the device.
