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 a noninvasive HbMet measurement by a DCI pulse oximeter sensor will be assessed by comparison to blood measurements from a laboratory analyzer.
Primary Outcome
Accuracy will be determined by comparing the noninvasive blood methemoglobin measurement of the pulse oximeter to that obtained from a blood sample and calculating the arithmetic root mean square (Arms) error value.
Interventions
- DEVICE DCI pulse oximeter sensor
