Primarily designed to be used by medical staff or responders with previous training, semi-automatic defibrillators rely on the user to administer the shock once the device has analysed the patient and deemed a shock to be necessary. Due to the human intervention required to initiate the shock, these devices include safeguards meaning that even untrained personnel are able to use them without the risk of accidentally causing harm.
