Abstract: Relocating medical devices for more efficient preventative maintenance. In one embodiment, a computer receives packets related to activity of medical devices, which are transmitted over a communication network. The computer performs deep packet inspection (DPI) of the packets, and calculates, based on results of the DPI, extents of utilization of each of the medical devices since receiving the most recent preventative maintenance. The computer identifies, based on the extents, first and second medical devices that are scheduled for upcoming preventative maintenance and are located in first and second rooms, respectively. An extent of utilization of the first medical device is below a predetermined threshold, and an extent of utilization of the second medical device is above the predetermined threshold. The computer recommends moving the first medical device to the second room and moving the second medical device to the first room.
