    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.

    摘要： A method for determining a physiological parameter in the presence of correlated artifact, including obtaining two digital waveforms, x and y, the waveforms being representative of the absorption of two wavelengths of electromagnetic energy received from a blood-perfused tissue, and where each of the waveforms has a component corresponding to a plethysmographic waveform and a component corresponding to the correlated artifact; calculating several weighted difference waveforms of the form x−R*y, where R is a multiplier, by varying R over a range; evaluating the several weighted difference waveforms using a shape characteristic of the weighted difference waveform; identifying a weighted difference waveform most closely representative of and one most different from the plethysmographic waveform; determining a pleth-based physiological parameter using the waveform most closely representative of the plethysmographic waveform; determining at least one artifact-based physiological parameter using the waveform most different from the plethysmographic waveform; and rejecting other possible candidate values for the pleth-based physiological parameter using the artifact-based physiological parameter.

    摘要： The use of two separate ensemble averagers for processing a detected waveform for use in calculating oxygen saturation and a pulse rate. The ensemble averager used for calculating oxygen saturation operates on a signal which has been normalized, while the ensemble averager for the pulse rate calculation operates on a signal which has not been normalized. The metrics chosen for the two paths through the two ensemble averagers can be varied to optimize the ensemble averaging for oxygen saturation or pulse rate calculations.

    摘要： In a system for measuring a physiological parameter using at least one wavelength of electromagnetic energy transmitted through living tissue, a method for determining an operational status of the system. The method includes receiving a data signal from at least one sensor, determining whether the received data signal is representative of the physiological parameter by sensing whether the at least one sensor is secured to the living tissue, and generating a status signal representative of the operational status of the system based on that determination. The determination includes measuring an output level corresponding to the at least one wavelength. The determination may also include analyzing a spectrum corresponding to the at least one wavelength to determine a percentage of energy contained in a subset of the spectrum, or monitoring an amplitude of the data signal for a given interval.
