Study 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 the noninvasive HbMet measurement by a Pulse Oximeter Sensor will be assessed by comparison to blood measurements from a laboratory analyzer.
Primary Outcome
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.In order to obtain the Arms value, the blood sample methemoglobin value is subtracted from the pulse oximeter methemoglobin value for a number of samples, the average of this difference is computed as the bias. The standard deviation of
