Details and patient eligibility

About

This study is designed to compare the accuracy of a noninvasive measurement of oxygen saturation compared to reference values obtained by a laboratory blood gas analyzer. Arterial blood samples will be collected from healthy adult subjects while undergoing a desaturation procedure wherein the concentration of oxygen inhaled is slowly reduced. The subject will then be returned to breathing room air.
