SpO2 Validation of Noninvasive Red Diamond Disposable Pulse Oximeter Sensor

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03124602

Brief Summary:
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 will be assessed by comparison to the oxygen saturation measurements from a laboratory blood gas analyzer.

Arm Intervention/treatment
Experimental: Test Subject
All subjects are enrolled into the test group and all subjects receive the noninvasive Red Diamond Disposable Pulse Oximeter Sensor
Device: Red Diamond Disposable Pulse Oximeter Sensor
Noninvasive Pulse Oximeter Sensor

Primary Outcome Measures :
  1. Accuracy of Red Diamond Disposable Pulse Oximeter Sensor by Arms Calculation [ Time Frame: 1-5 hours per subject ]
    Accuracy will be determined by comparing the noninvasive blood oxygen saturation measurement of the pulse oximeter to that obtained from a blood sample and calculating the Accuracy root mean square (ARMS) error value. In order to obtain the Arms value, the blood oxygen saturation measurement form a laboratory pulse Co-Oximeter is subtracted from the pulse oximeter oxygen saturation measurement for a number of samples, the average of this difference is computed as the bias. The standard deviation of the differences is computed as the precision. The square root of the sum of the squares of bias and precision is computed as the ARMS Error value.
