Abstract: This disclosure describes systems, methods, and computer programs for notifying about availability of a medical device to receive maintenance. In one embodiment, a computer receives: (i) packets related to medical device activity, which are transmitted over a communication network, and (ii) an identifier of a certain medical device that is to receive maintenance. The computer performs deep packet inspection (DPI) of the packets. The computer determines, based on a result of DPI of a first packet, that the certain medical device is being utilized to treat a patient, so it notifies not to use the certain medical device in additional treatments. Based on a result of DPI of a second packet, which was transmitted after the first packet, the computer determines that the certain medical device was no longer being utilized to treat any patient, so the computer notifies that the certain medical device is available for maintenance.
