Final answer:
AEDs deliver a high-voltage shock dose which is a large charge in a short burst, used to correct arrhythmias and allow the heart to regain its natural rhythm. The AED automatically determines the appropriate energy and waveform for the patient's specific condition.
Step-by-step explanation:
A student asked about the kind of shock dose that some Automated External Defibrillators (AED) can deliver. In a cardiac emergency, AEDs are crucial devices that deliver a large charge in a short burst to terminate arrhythmias such as ventricular fibrillation, allowing the heart's natural pacemaker to resume normal rhythm.
The key to the effectiveness of an AED is not solely the shock's voltage but the overall energy and waveform appropriate to the patient's condition which it automatically determines. This shock is a high-voltage dose, which is why option 1) High voltage shock dose is the correct answer. The severity of a shock delivered for therapeutic purposes is managed to ensure safety and effectiveness, contrasting with accidental shocks that vary in severity based on current, path, duration, and frequency.
