NCT03125005

Brief Summary

In this study, the level of methemoglobin (HbMet) will be increased in a controlled manner by administering sodium nitrite intravenously in healthy volunteers. The accuracy of a noninvasive HbMet sensor will be assessed by comparison to blood measurements from a laboratory analyzer.

Outcome Measures

Primary Outcomes (1)

  • Accuracy of Sensor by Arms Calculation

    Accuracy willl be determined by comparing the noninvasive blood methemoglobin measurement (expressed as a percentage of total hemoglobin) of the pulse oximeter to that obtained from a blood sample and calculating the arithmetic root mean square(Arms) error value.
