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.
