SpO2 System Accuracy Testing With Different Sensors

SpO2 System Accuracy Testing

A study to test the accuracy of SpO2 sensors with various patient monitors, co-oximeters, and modules.

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.
