Physiological measurement communications adapter
First Claim
1. A communications adapter configured to wirelessly communicate a first signal from a patient site to a remote site and to adapt the first signal to a particular patient monitor at the remote site, the communications adapter comprising:
- a first processor configured to generate said first signal responsive to a sensor signal received from a noninvasive sensor attached to a tissue portion of a patient, wherein said sensor signal is indicative of at least one physiological parameter of a patient;
a communications link configured to wirelessly transmit the first signal from a first site proximate the patient and to receive the first signal at a second site; and
a second processor that adapts the first signal to a usually incompatible particular patient monitor at the second site so that the particular patient monitor derives physiological measurements from the adapted first signal that are generally equivalent to measurements derivable from the first signal by a monitor compatible with the noninvasive sensor.

Abstract
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.

8. A physiological measurement method comprising:
-
inputting a sensor signal at a patient location; generating a physiological waveform responsive to the sensor signal; reducing the sample rate of the physiological waveform; wirelessly communicating the reduced sample rate physiological waveform from the patient location to a monitor location; adapting the reduced sample rate physiological waveform to a particular patient monitor at the monitor location; and outputting the adapted physiological waveform to a sensor port of the patient monitor so that 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.
