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.

(canceled)
A pulse oximetry system comprising:
- a portable patient monitoring device comprising:
- a pulse oximetry sensor configured to be attached to a digit of a patient, the pulse oximetry sensor including at least:
- a light emitter configured to emit light into a tissue site of the digit of the patient;
- a light detector configured to output a sensor signal responsive to at least a portion of the emitted light after attenuation by tissue of the tissue site;
- and
- a cable extending from the pulse oximetry sensor and configured to electrically convey the first signal;
- a housing configured to be secured to a lower arm of the patient, wherein the cable is configured to interface with the housing on a side of the housing and extend from the side of the housing along a path perpendicular to the side of the housing;
- a strap mountable to the housing, the strap configured to secure the housing to the lower arm of the patient;
- one or more signal processors configured to:
- cause activation of the light emitter to emit light;
- receive the sensor signal from the light detector;
- determine, based at least in part on the sensor signal, measurements of physiological parameters including at least oxygen saturation and pulse rate;
- and
- generate a transmit signal including information indicative of the measurements of the physiological parameters;
- a signal transmitter configured to wirelessly transmit the transmit signal to a receiver computing system;
- and
- a battery configured to power the portable patient monitoring device including at least the one or more signal processors and the signal transmitter;
- and
- the receiver computing system configured to:
- receive, by a signal receiver of the receiver computing system, the transmit signal from the portable patient monitoring device;
- and
- cause display, on a display of the receiver computing system, of the measurements of the physiological parameters of the patient.
