Accuracy of Oxygen Saturation (SpO2) Noninvasive Pulse Oximeter Sensor (RD Disposable) Under Motion Conditions

In this study, the level of oxygen within the blood will be reduced in a controlled manner by reducing the concentration of oxygen the study volunteer breathes. The accuracy of a noninvasive pulse oximeter sensor under motion conditions will be assessed by comparison to the oxygen saturation measurements from a laboratory blood gas analyzer.
