Study Summary

The aim of this study is to test the accuracy of EmbracePlus computed SpO2 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 the subject device 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.

Primary Outcome

SpO2 as measured by the subject device during periods of low motion will be compared to the oxyhemoglobin saturation (SaO2) as measured by direct oximetry with a Radiometer ABL-90 multi-wavelength oximeter
