    摘要: A sensor for pulse oximetry or other applications utilizing spectrophotometry may be adapted to reduce motion artifacts by fixing the optical distance between an emitter and detector. A flexible sensor is provided with a stiffening member to hold the emitter and detector of the sensor in a relatively fixed position when applied to a patient. Further, an annular or partially annular sensor is adapted to hold an emitter and detector of the sensor in a relatively fixed position when applied to a patient. A clip-style sensor is provided with a spacer that controls the distance between the emitter and detector.

In an embodiment, the low-friction material may include, for example, a fluoropolymer, a polypropylene, or a polyethylene. Additionally, in an embodiment, an internal surface of the sensor that is in contact with the patient may have a relatively high-friction coating, such as an adhesive. In an embodiment, a stack of adhesive layers may be disposed on the internal surface around one or more light emitting and/or detecting optics.

    摘要: The present disclosure relates, according to some embodiments, to devices, systems, and methods for estimating a physiological parameter in the presence of noise. For example, the disclosure relates, in some embodiments, to devices, systems, and methods for assessing (erg., estimating, measuring, calculating) oxygen saturation (SpO2). Methods of assessing SpO2 may include assessing a noise metric associated with motion artifact. In some embodiments, a percentage (e.g., an empirically determined percentage) of a noise metric may be simply added to the SpO2 estimate to produce a corrected SpO2 estimate. An oximetry algorithm may include, according to some embodiments, combining multiple internal SpO2 estimates and associated noise and/or signal quality metrics (e.g., using a radial basis neural network) to produce a modified (e.g., corrected) SpO2 estimate (e.g., rather than merely selecting the estimate from a finite number of candidates). A modified SpO2 estimate may include little or no movement-based error.

    摘要: The present disclosure is generally directed to identifying and/or analyzing high resolution variations in a measured physiologic parameter, such as blood oxygen saturation (SpO2) measured using pulse oximetry. Present embodiments may include a system including a sensor comprising an emitter capable of emitting light at different wavelengths into a tissue bed, and a detector capable of detecting the light from the emitter after dispersion and/or reflection by the tissue bed. Further, the system may include a pulse oximeter capable of receiving signals from the sensor that are indicative of characteristics of the light detected by the detector, and utilizing the signals to estimate blood oxygen saturation values over time at a high resolution to facilitate detection of variations in the blood oxygen saturation values that are smaller in magnitude than an accuracy, display precision, and/or calibration of the blood oxygen saturation values.
