简要总结
A study to test the accuracy of SpO2 sensors with various patient monitors, co-oximeters, and modules.
详细描述
The U-TruSignal with different sensors is feasible for noninvasive and continuous SpO2 monitoring and meets the specified measurement accuracy when compared to a co-oximetry gold reference.

The Accuracy Root Mean Square (ARMS) calculation is used to measure accuracy of the test SpO2 device compared to reference SpO2 device. A scatterplot is created with the forehead sensor saturation on the y-axis and the measured blood saturation on the x-axis. The line of identity is drawn representing the ideal points, meaning that the forehead sensor saturation is always the same as the blood saturation. The dispersion of the actual data points around the line of identity can be measured using a statistical calculation called Arithmetic Root Mean Square (ARMS). The smaller ARMs the closer the data points lie around the line of identity, representing a more accurate sensor as accurate and appropriate. Data analysis follows ISO 80601-2-61, 2011, Annex EE and the FDA Guidance Document for Pulse Oximeters (FDA Draft Guidance, July 19, 2007).
