NCT04562584

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

    1 hour

  • Diagnosis of asthma, sleep apnea, or use of CPAP.
  • Subject has diabetes.
  • Subject has a clotting disorder.
