Accuracy of Methemoglobin Measurement of Various Rainbow Pulse Oximeter Sensors

Completed · Not applicable

Conditions studied: Healthy

In brief

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.
