    摘要： A device includes a housing, an emitter, a detector, and a processor. The housing has a body contact surface. The emitter is coupled to the housing and has an emission surface and has an electrical terminal. The emission surface is configured to emit light proximate the body contact surface in response to a signal applied to the electrical terminal. The detector is coupled to the housing. The detector has a sense surface and an output terminal. The detector is configured to provide an output signal on the output terminal in response to light detected at the sensor surface. The processor is configured to implement an algorithm to determine a tissue site based on the emitted light and based on the detected light.

    摘要： An oximeter can include a sensor and a processor. The processor can access signal information corresponding to a test signal. The signal information can correspond to a characteristic. The characteristic can be determined using at least one of an AC component and a DC component. The processor can compare the characteristic and a reference value. The processor can adjust the signal, based on the comparison, to set a relationship between the characteristic and the reference value.

    摘要： A method includes affixing a co-planar sensor on a surface, using a processor, and providing an output. The method includes affixing a co-planar sensor on a surface at a first tissue site. The sensor has a force transducer disposed at an aperture of a rigid guard member. The guard member and the transducer are in co-planar alignment. The transducer is configured to provide an electrical signal corresponding to an internal pressure at the first tissue site. The method includes using the processor to compare the internal pressure with a reference value. Based on the comparison, the method includes providing an output corresponding to compartment syndrome at the first tissue site.

    摘要： A device includes a housing, an emitter, a detector, and a processor. The housing has a body contact surface configured for affixation to a tissue site of a body. The emitter is coupled to the housing and has an emission surface and an electrical terminal. The emission surface is configured to emit light proximate the body contact surface in response to a signal applied to the electrical terminal. The detector is coupled to the housing. The detector has a sense surface and an output terminal. The detector is configured to provide an output signal on the output terminal in response to light detected at the sensor surface. The processor is coupled to the electrical terminal and coupled to the output terminal. The processor is configured to implement an algorithm to monitor for an interruption between the body contact surface and the body and configured to generate an interrupt signal corresponding to the monitoring.

    摘要： A device includes a digit probe, a plurality of optical elements, a processor, and a communication module. The digit probe has an interior surface and has an exterior surface. The interior surface is configured to engage a digit and the exterior surface is configured to engage a tissue site associated with the digit. The plurality of optical elements is coupled to at least one of the interior surface and the exterior surface. The plurality of optical elements includes at least one emitter and includes at least one detector. The processor is coupled to the plurality of optical elements. The processor is configured to generate a measure of arterial oxygenation corresponding to the digit and configured to generate a measure of regional oxygenation corresponding to the tissue site. The communication module is coupled to the processor. The communication module is configured to communicate the measure of arterial oxygenation and regional oxygenation with a remote device.

    摘要： A system includes a garment and a sensor module. The garment includes an engagement feature. The garment is configured to encompass a first location on a body. The engagement feature is positioned in fixed alignment with the garment. The sensor module includes a sensor housing and includes a sensor having an electrical node. The sensor is configured to provide an electrical output on the node. The housing has a complementary feature. The complementary feature is configured to couple and decouple with the engagement feature. The electrical output is based on a measure of a physiological parameter associated with the body and is based on site information corresponding to the engagement feature.
