Abstract: The present disclosure describes the derivation and measurement of a fractional oxygen saturation measurement. In one embodiment, a system includes an optical sensor and a processor. The optical sensor can emit light of multiple wavelengths directed at a measurement site of tissue of a patient, detect the light after attenuation by the tissue, and produce a signal representative of the detected light after attenuation. The processor can receive the signal representative of the detected light after attenuation and determine, using the signal, a fractional oxygen saturation measurement based on two or more different measures of fractional oxygen saturation.

Abstract: A medical characterization system is configured to input medical-related continuous parameters and discrete data so as to calculate a characterization timeline indicative of a physiological condition of a living being. A data source is in sensor communications with a patient so as to generate a continuous parameter. The data source also provides test data responsive to the patient at a test time. The test data is available to a characterization processor at a result time. The characterization processor is also responsive to the continuous parameter so as to generate a medical characterization as a function of time. A characterization analyzer enables the characterization processor to update the medical characterization in view of the test data as of the test time.

Abstract: The present disclosure describes embodiments of a patient monitoring system and methods that include the measure and display of hemoglobin statistics. In an embodiment, total hemoglobin trending is displayed over a period of time. Statistics can include frequency domain analysis, which may be unique for each patient monitored. The total hemoglobin trending and/or statistics can further be used to help control the treatment of a patient, such as being used to control IV administration.

Abstract: An physiological measurement device provides a device body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The device body is flexed so as to position the housing over a tissue site. The device body is unflexed so as to attach the housing to the tissue site and position the optical assembly to illuminate the tissue site. The optical assembly is configured to transmit optical radiation into tissue site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.

Abstract: A patient monitor for displaying a physiological signal can include a visual element having a middle portion indicative of a transition in the physiological signal between physiological states. The visual element can also include first and second extremity portions, the first extremity portion extending from the middle portion in a first direction and the second extremity portion extending from the middle portion in a second direction. The visual element can also include an actionable value indicator to specify a value about the middle portion and the first and second extremity portions. The patient monitor can also include a processor configured to cause the value indicator to actuate in both the first and second directions according to changes in the physiological signal.

Abstract: A physiological monitor has a sensor port configured to attach and communicate with a sensor. A processor board is in communications with the sensor port and has a board digital signal processor (DSP). Firmware residing on the processor board is executable by the board DSP so as to calculate physiological parameters in response to a sensor signal received from the sensor. Upgrade tools are individually attachable to the sensor port in lieu of the sensor so as to designate to the processor board which of the physiological parameters, if any, to calculate when the sensor is attached to the sensor port.

Abstract: Medical patient monitoring devices that have the capability of detecting the physical proximity of a clinician token are disclosed. The medical patient monitoring devices may be configured to perform a selected action when the presence of a clinician is detected. The selected action may be dependent upon an attribute of the circumstances surrounding detection of the clinician.

Abstract: A sensor port is adapted to connect to either a sensor or a data source. A reader is configured to identify which of the sensor and the data source is connected to the sensor port. A data path is configured to communicate an analog signal associated with the sensor and digital data associated with the data source to a signal processor according to the identification made by the reader.

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.
