摘要： A physiological sensor includes a light source in optical communication with a light detector. A controller is in communication with the light detector via a connector. A booster circuit is in communication with the light detector and the connector. The booster circuit may be configured to buffer signals generated by the light detector and reduce an input capacitance on either the controller or terminals of the connector. In various embodiments, the booster circuit may be disposed on the connector for a reusable cable or a disposable sensor pad.

摘要： A system and method for non-invasively estimating the tissue blood oxygen saturation level of a human subject, including so-called “outliers”, whose physiological make-up causes previously-known techniques to generate invalid tissue blood oxygen saturation estimations. The system includes a computing device and a sensor. The sensor includes a light source configured to emit light of at least four different wavelengths, one at a time. The sensor also includes two light detectors, each positioned a different distances from the light source. Optical density measurements are taken by the light detectors and provided to the computing device. A first tissue blood oxygen saturation value is computed using the optical density measurements associated with three of the four wavelengths, and a second tissue blood oxygen saturation value is computed using the optical density measurements associated with four of the wavelengths. The first and second tissue blood oxygen saturation values are compared, and the human subject is identified as an “outlier” based upon that comparison.

摘要： A patient monitoring system has a processor and a spectrophotometric sensor. The sensor is configured to be affixed to a patient to communicate signals associated with real time spectrophotometric measurements to the processor. The system further includes memory for storing data and computer instructions. The processor is configured to execute instructions stored in the memory to calculate a trend statistic based on a group of the signals received from the sensor. The processor is further configured to execute instructions stored in the memory to cause real time information associated with the spectrophotometric measurements and information associated with the trend statistic to be displayed on a visual user interface.
