Abstract

A wireless patient monitoring system. In one embodiment the system has a first patient monitoring subsystem including a plurality of sensors and sensor modules; and a processor-transceiver in communication with the plurality of sensors and sensor modules; and a first clinician display subsystem including a processor-transceiver. The processor-transceiver of the first clinician display subsystem broadcasts, on a first predetermined frequency, the frequency the processor-transceiver of the first clinician display subsystem will use to communicate with the processor-transceiver of the first patient monitoring subsystem. The processor-transceiver of the first patient monitoring subsystem then transmits and receives data on the frequency that the processor-transceiver of the first clinician display subsystem will use to communicate with the processor-transceiver of the first patient monitoring subsystem. The processor-transceiver of the first patient monitoring subsystem reverts to the first frequency if communication with the processor-transceiver of the first clinician display subsystem is lost.
