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.

摘要： A memory in a sensor is used to store multiple coefficients for a physiological parameter. In one embodiment, not only are the sensor's specific calibration coefficients stored in a memory in the sensor for the formula to determine oxygen saturation, but multiple sets of coefficients are stored. The multiple sets apply to different ranges of saturation values to provide a better fit to occur by breaking the R to SpO2 relationship up into different pieces, each described by a different function. The different functions can also be according to different formulas for determining oxygen saturation.

摘要： Forehead oximetry sensor devices and methods for determining physiological parameters using forehead oximetry sensors. One method includes placing an oximetry sensor on the forehead of a patient, such that the sensor is placed on the lower forehead region, above the eyebrow with the sensor optics placed lateral of the iris and proximal the temple; and operating the pulse oximeter to obtain the physiological parameter. In one aspect, the method also includes providing and placing a headband over the oximetry sensor, or alternately, the sensor is a headband-integrated sensor. The headband has an elastic segment sized to fit around the patient's head. The headband also includes a non-elastic segment that is smaller than and attached with the elastic segment. The non-elastic segment is sized to span a portion of the elastic segment when the elastic segment is stretched. In addition, the non-elastic segment is larger than the portion of the elastic segment it spans when the elastic segment is not stretched. When the headband or the headband-integrated sensor is sufficiently tight, it delivers a pressure in the range higher than the venous pressure and lower than the capillary pressure to the forehead of the patient.
