Accuracy of SpO2 for Noninvasive Pulse Oximeter Sensor (RD DCI)

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: NCT03124797

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.

Device: RD DCI Sensor
Noninvasive pulse oximeter sensor

Primary Outcome Measures :
  1. Accuracy of Sensor by Arms Calculation [ Time Frame: 1-5 hours ]
    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 arithmetic root mean square(Arms) error value. In order to obtain the Arms value, the blood oxygen saturation measurement 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.
