Desaturation Validation of INVSENSOR00009

Study Overview
=================
Brief Summary
-----------------
This study is designed to measure the trending accuracy of a noninvasive measurement of cerebral oxygen saturation. One Large sensor (adult sensor) and one INVSENSOR00009 will be placed on the subject's forehead. The values obtained by the INVSENSOR00009 will be compared to the values collected with the adult sensor.Data will be collected from healthy adult subjects while undergoing a desaturation procedure wherein the concentration of oxygen inhaled is slowly reduced until the subject's arterial oxygen saturation is approximately 70%. The subject will then be returned to inhaling room air.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Trending Regional Oxygen Saturation Accuracy of the INVSENSOR00009 Relative to the Control Sensor by Arms Calculation | Trending ARMs accuracy is defined as root mean squared relative error of all data points of all subjects. Accuracy of the sensors will be determined by comparing regional oxygen saturation (rSO2) readings from INVSENSOR00009 and control sensor and calculating the Arithmetic root mean square (ARMS) value. | 1-5 hours |
