NCT04112784

Brief Summary

This study is designed to compare the accuracy of a noninvasive measurement of oxygen saturation compared to reference values obtained by a laboratory blood gas analyzer. Arterial blood samples will be collected from healthy adult subjects while undergoing a desaturation procedure wherein the concentration of oxygen inhaled is slowly reduced. The subject will then be returned to breathing room air.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Oxygen Saturation (SpO2) Accuracy of Sensor

    Performance of the sensors will be determined by comparing the noninvasive oxygen saturation measurement (SpO2) of the pulse oximeter sensors to the arterial oxygen saturation (SaO2) value obtained from a reference blood sample and calculating the Accuracy root square mean (ARMS) value.

    1-5 hours

Study Arms (1)

INVSENSOR00039

EXPERIMENTAL

All subjects who are enrolled into the test group and participate in data collection receive the noninvasive INVSENSOR00039 sensor.

Device: INVSENSOR00039
