    摘要: A pulse oximeter sensor comprising an emitter and a detector coupled to a substrate layer and a partially opaque layer located on a patient contact side of the sensor and covering the emitter. The partially opaque layer is configured to attenuate light shunted via the partially opaque layer from the emitter to the detector, and may be configured such that less than 10% of the light detected by the detector is shunted light.

    摘要: A pulse oximeter sensor comprising a light emitter and a detector disposed on a substrate layer with a plurality of perforations or variations in thickness between the light emitter and the detector. The plurality of perforations or variations in thickness blocks or scatters light shunted via the substrate layer from the light emitter to the detector, and may be configured such that less than 10% of the light detectable by the detector is shunted light.

    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.
