US Patent 7844315 Physiological measurement communications adapter

A sensor signal is input at a patient location and a physiological waveform responsive to the sensor signal is generated. The physiological waveform is wirelessly communicated from the patient location to a monitor location. The physiological waveform is adapted to a particular patient monitor at the monitor location. The adapted physiological waveform is output to a sensor port of the patient monitor. Accordingly, the patient monitor derives physiological measurements from the adapted physiological waveform that are generally equivalent to measurements derivable from the physiological waveform by a monitor compatible with the sensor signal.
