研究概览
简要总结
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 until the subject's arterial oxygen concentration is approximately 70%. The subject will then be returned to inhaling room air.

研究组 & 干预措施
INVSENSOR00006
Experimental
All subjects consented are enrolled into the test group and received the INVSENSOR00006.
干预措施: INVSENSOR00006 (Device)
结局指标
主要结局
Oxygen Saturation (SpO2) Accuracy of Sensor
时间窗: 1-5 hours
Performance of the sensors will be determined by comparing the noninvasive oxygen saturation measurement (SpO2) of the pulse oximeter sensors to the arterial oxygen saturation (SaO2) value obtained from a reference blood sample and calculating the Arithmetic root mean square (ARMS) value.
