What type of External Defibrillator unit requires the provider to initiate defibrillation once attached?

The correct answer is semi-automatic defibrillator. This type of external defibrillator requires the healthcare provider to initiate the shock after the device has analyzed the heart rhythm. Once the electrodes are placed on the patient’s chest and the device prepares for shock delivery, the provider must confirm that it is safe to deliver the shock and then press the button to administer it. This process ensures that the provider retains control over the defibrillation process.

In contrast, an automatic defibrillator delivers a shock without any intervention from the provider, while non-automatic defibrillators, although they may require manual intervention, are not the standard terminology used in the field. Stationary defibrillators typically refer to devices installed in one location rather than being portable or handheld. Understanding these distinctions is vital for effective emergency response in life-threatening situations.
