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.
Claims29
(canceled)
A pulse oximetry system comprising:
- a receiving computing device comprising:
- a signal receiver;
- and
- a display capable of displaying physiological parameter and waveform data;
- and
- a portable patient monitoring device comprising:
- a light emitter configured to emit light into a tissue site a 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;
- at least one user input mechanism configured to at least enable activation of the portable patient monitoring device in response to inputs from a user;
- one or more signal processors configured to:
- cause activation of the light emitter to emit light;
- receive the sensor signal from the light detector, the sensor signal useable to determine physiological parameters including at least oxygen saturation, pulse rate, and perfusion index of the patient;
- and
- perform a first processing of the sensor signal to generate a transmit signal;
- a signal transmitter configured to wirelessly transmit the transmit signal to the receiving computing device;
- and
- a battery configured to power the portable patient monitoring device including at least the one or more signal processors and the signal transmitter, wherein the receiving computing device is configured to:
- receive the transmit signal from the portable patient monitoring device;
- perform a second processing on the transmit signal in order to determine measurements of the physiological parameters including at least oxygen saturation, pulse rate, and perfusion index;
- and
- cause display, on the display of the receiving computing device, of the measurements of the physiological parameters of the patient.
