Brief Summary
The aim of this project is to test the accuracy of pulse oximeters (devices intended to measure oxygen saturation in blood noninvasively) during mild, moderate and severe hypoxia (a lower-than-normal concentration of oxygen in arterial blood); ie, a range of arterial HbO2 saturations from 100 to down to 70%. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxyhemoglobin (hemoglobin carrying oxygen) saturation, that is arterial blood sample processed in a laboratory.

Outcome Measures
Primary Outcomes (1)
Saturation level measurement
Induction of hypoxia by having subjects breathe mixtures of nitrogen, room air, and carbon dioxide to allow measurement of oxyhemoglobin saturation between 70-100%. Each plateau level of oxyhemoglobin saturation was maintained for at least 30 seconds or until reference pulse oximeters readings were stable

Eligibility Criteria
You may qualify if:
- The subject is male or female, aged ≥18 and \<50.
- The subject is in good general health with no evidence of any medical problems.
- The subject is fluent in both written and spoken English.
- The subject has provided informed consent and is willing to comply with the study procedures.
You may not qualify if:
- The subject is obese (BMI\>30).
- The subject has a known history of heart disease, lung disease, kidney or liver disease.
- Diagnosis of asthma, sleep apnea, or use of CPAP.
- Subject has diabetes.
- Subject has a clotting disorder.
- The subject 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.
