摘要： Monitoring cerebral autoregulation may include determining one or more autoregulation indices incorporating cerebral blood flow and blood pressure measurements and/or indices. Measurement techniques may be invasive or non-invasive. Various combinations of data, e.g., oximeter data, electrocardiogram data, blood pressure data, hemoglobin data, and heart rate data, may be used to create various indices. Many of the indices may be based on correlations of data. A display may indicate several of the indices.

摘要： A system includes a light source, a photodetector in optical communication with the light source, and a processor in communication with said photodetector and configured to output a signal representing oxygen saturation independent of an interfering signal from an interfering source. The system may further include an analog-to-digital converter in communication with the processor that is configured to digitize a signal from the photodetector by oversampling and output oversampling data to the processor. The processor may include an averaging filter that averages the oversampling data received from said analog-to-digital converter prior to decimation to generate an oversampling number.

摘要： A physiological sensor includes a light source and an age detector circuit in communication with the light source. The age detector circuit is configured to determine an age of the light source based on current-voltage characteristics of said light source. In addition, a method includes measuring an initial I-V characteristic and an actual I-V characteristic of the light source, and comparing the initial I-V characteristic to the actual I-V characteristic since changes in the I-V characteristics indicate aging. Actual I-V characteristics can be compared between light sources when they age at different rates to determine light source aging. Moreover, the method may include updating the memory device with the actual I-V characteristic at predetermined times.
