High energy is delivered during defibrillation. This can also be dangerous for the rescuer if he or she touches the victim while the current is being delivered. However, biphasic defibrillation does not pose a danger to the rescuer on a wet surface.
The devices suitable for first aiders are designed in such a way that even if the current is delivered on a damp surface (rain, snow), there should be no danger to the rescuer - in these circumstances, however, keep the greatest possible distance, do not kneel directly next to the affected person. After the electric shock has been delivered, the victim can be touched again immediately without danger. The person is not "charged".
Since high energy is used, it is important not to touch the person at the moment the current is delivered (when the device tells us to keep our distance).
Evidence-based considerations of the dangers of accidental defibrillation
Discussions about the dangers of defibrillation are increasing, not least because of the widespread use of AEDs in lay settings. Questions about the dangers for users of defibrillators in special situations, such as simultaneous chest compressions or defibrillation on a conductive surface, are numerous. In the course of an extensive literature search, relevant publications were selected and assigned to corresponding levels of evidence. The result showed that overall very little literature is available that deals with the risk to a user during defibrillation. It should be noted that some reservations about the use of defibrillators can be overcome. Biphasic shock delivery during ongoing chest compressions is certainly possible under certain conditions. Even on wet ground, biphasic defibrillation poses no danger to the rescuer.
