Abstract: Continuous core body temperature measurements are made during hypothermic operations, where the core body temperature of the patient is lowered to reduce swelling. Caregivers monitor the patient's core body temperature to prevent damage that can occur to the patient if the patient's core body temperature becomes too low. To accurately determine the core body temperature of the patient, a temperature monitoring system measures the temperature at or near the surface of the patient and through at least a portion of a thermal block at multiple locations.

Abstract: A noninvasive blood pressure monitor. The noninvasive blood pressure monitor may include an inflatable cuff, a pressure transducer, one or more air pumps, and a processor. The processor may control the air pump(s) so as to initiate inflation of the cuff. The processor may also identify an oscillometric signal in an output of the pressure transducer, and may determine an envelope of the oscillometric signal. The processor may also determine one or more characteristics of the envelope of the oscillometric signal, and may control the air pump(s) so as to stop inflation of the cuff based on the one or more characteristics of the envelope of the oscillometric signal.

Abstract: A patient monitor can noninvasively measure a physiological parameter using sensor data from a nose sensor configured to be secured to a nose of the patient. The nose sensor can include an emitter and a detector. The detector is configured to generate a signal when detecting light attenuated by the nose tissue of the patient. An output measurement of the physiological parameter can be determined based on the signals generated by the detector. The nose sensor can include a diffuser configured to disseminate light exiting from the emitter into or around a portion of the patient's body. The nose sensor can also include a lens configured to focus light into the detector.

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 patient monitor can noninvasively measure a physiological parameter using sensor data from different measurement sites on a patient. The patient monitor can combine all sensor data from different measurement sites into a raw or minimally processed data form to generate a single, robust measurement of the physiological parameter. An optical sensor of a patient monitor can include multiple photodetectors each configured to generate a signal when detecting light attenuated by the patient's tissue. A measurement of a physiological parameter can be determined based on at least in part on the multiple signals from the multiple photodetectors.
