SpO2 Accuracy of Noninvasive Disposable Pulse Oximeter Sensor With 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 participant breathes. The accuracy of a noninvasive pulse oximeter sensor will be assessed by comparison to the oxygen saturation measurements from a laboratory blood gas analyzer. It is required that the Accuracy Root Mean Square (ARMS) performance of the Stryker pulse oximetry sensors will meet a specification of +/-3% or better in motion conditions for the range of 70 - 100% SaO2 (typically, saturation is determined once with air breathing and then at one of 6 levels, e.g. 94%, 90%, 85%, 80%, 75% and 70% saturation for about 30-60 seconds at each level), thereby demonstrating an acceptable SpO2 accuracy performance specification. Motion is defined as controlled rubbing or tapping of the subject's fingers in a 2-4 Hz or random sine motion with 2-3 cm amplitude.
