A method for tracking a device not actively sending patient data to a network of medical devices is disclosed. The method comprises the device giving a signal at a time interval; an active hub listening to the device at the time interval; the active hub storing information about the device; and the active hub continuing to listen at the time interval to the device until the device actively sends patient data, or until no more signals are heard from the device. A system for tracking a device of a network of medical devices is also disclosed. The network comprises a hub and at least one device. The at least one device is configured to give a signal to the hub at a time interval, if the at least one device does not actively send patient data. The hub is configured to listen at the time interval to any devices not actively sending patient data. The hub is configured to store information about any devices not actively sending patient data. The hub is configured to continue listening to any devices not actively sending patient data until all devices actively send patient data, or until no more signals are heard from any devices not actively sending patient data.
