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.

- Diagnosis of asthma, sleep apnea, or use of CPAP.
- Subject has diabetes.
- Subject has a clotting disorder.
- The subject has a hemoglobinopathy or history of anemia, per subject report or the first blood sample, that in the opinion of the investigator, would make them unsuitable for study participation.
- The subject has any other serious systemic illness.
- The subject is a current smoker.
- Any injury, deformity, or abnormality at the sensor sites that in the opinion of the investigators' would interfere with the sensors working correctly.
