The study will include at least 10 subjects (up to 14 if needed to reach the 200 necessary data points to meet the ISO 80601-2-61:2017).~Per FDA guidance, at least 2, or 15% of the subjects will have dark skin.
The aim of this project is to test the accuracy of pulse oximeters during mild, moderate and severe hypoxia. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxyhemoglobin saturation (arterial blood sample processed in a laboratory hemoximeter). The data obtained is submitted by pulse oximeter manufacturers to the FDA for device approval.
