An illustrative apparatus may include a UAV request apparatus having a housing with at least one interface configured to accept one or more inputs that are each indicative of a particular type of medical situation. A control system may be configured to receive, via the interface, a first input that corresponds to a first type of medical situation in which a defibrillator is configured to provide medical support; and send, via a first network interface to an access system for a network of UAVs, a medical support request including a unique electronic identifier for the apparatus and an indication of the first type of medical situation, such that a UAV delivers a defibrillator to a location associated with the unique electronic identifier.
