Accuracy of Pulse Oximeters With Profound Hypoxia

Completed

Conditions studied: Oximetry, Pulse

In brief

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.
