Title: Innovations by Margaret S. Mortz
Introduction
Margaret S. Mortz is a notable inventor based in Lafayette, Colorado. She has made significant contributions to the field of medical technology, particularly in the development of pulse oximetry devices. With a total of four patents to her name, her work has had a profound impact on patient monitoring and healthcare.
Latest Patents
One of her latest patents focuses on an improved pulse oximeter for SpO2 determination. This innovative device preprocesses sets of red and infrared signals received from the probe to eliminate ambient light and noise. By de-exponeniating the signals, the device enhances the linearity of the processed data. This allows for the application of statistical techniques such as linear regression and linear correlation to fit a best-fit straight line to the processed data points. The analysis yields a linear regression slope and a goodness of fit correlation coefficient. If the correlation coefficient falls below a predetermined threshold, it indicates that a distorted signal has been received from the probe. This feature enables the pulse oximeter to detect probe-off conditions and/or patient motion. The computed linear regression slope is then converted to a RRatio, which is utilized in an empirical calibration formula to compute the average SpO2 value. Notably, the minimum size of the data set required for high-confidence calculations is significantly smaller than a pulse period, allowing for a faster response to changing input data.
