1. A pulse oximetry system comprising:
- a receiver configured to communicate with a monitor device; and
a wrist-mountable pulse oximetry device including;
a wrist mount usable to mount the wrist-mountable pulse oximetry device on a wrist of a user;
a housing coupled to the wrist mount;
a sensor interface housed by the housing and configured to receive a sensor signal from a pulse oximetry sensor, the sensor signal indicative of oxygen saturation and pulse rate of the user; and
a transmitter housed by the housing and configured to;
modulate a first baseband signal responsive to said sensor signal so as to generate the transmit signal; and
wirelessly transmit the transmit signal to the receiver,wherein the receiver is further configured to;
receive the wirelessly transmitted signal from the wrist-mountable pulse oximetry device; and
adapt the received wirelessly transmitted signal to a monitor-compatible signal utilizing characterization information specific to the monitor device, the monitor-compatible signal adapted for compatibility with the monitor device, the monitor-compatible signal usable by the monitor device to provide physiological parameter measurements consistent with the sensor signal received from the pulse oximetry sensor.

Abstract
A sensor interface is configured to receive a sensor signal. A transmitter generates a transmit signal. A receiver receives the signal corresponding to the transmit signal. Further, a monitor interface is configured to communicate a waveform to the monitor so that measurements derived by the monitor from the waveform are generally equivalent to measurements derivable from the sensor signal.
