简要总结
The purpose of this study is to evaluate the oxygen saturation accuracy performance of Belun Ring Oximeter placed on the index fingers during non-motion conditions
详细描述
The purpose of this study is to evaluate the SpO2 accuracy performance of Belun Ring Oximeter placed on the index fingers during non-motion conditions over the range of 70-100% SaO2, arterial blood samples, assessed by CO-Oximetry. It is expected that the Accuracy Root Mean Square (ARMS) performance of the oximetry system will meet the required specification of ARMS of 3.5% or less allowed for reflectance technology in non-motion conditions for the range of 70 - 100% SaO2.
The Clinimark proprietary Desaturation Fixture with Automated Data Collection is a single limb blow by system used to deliver medical grade oxygen and nitrogen gas mixtures to induce various hypoxic levels in subjects at a slow steady rate allowing an automatic marking and collection of the Control or secondary Transfer reference Pulse Oximeter and other pulse oximetry systems at 1 second intervals.
The Control Pulse Oximeter, an FDA cleared device, is used to monitor the oxygen saturation levels real time throughout the study for subject safety and to target stable plateaus. This device is used to assess the stability of the data.
Multi-parameter monitor used during the study to observe a subject's vital signs including ECG tracing, heart rate, respiratory rate, end-tidal CO2 with capnograph, secondary monitor for the oxygen concentration being delivered to the subject.
A whole blood analyzer (CO-Oximeter) is used as the reference standard device for obtaining the functional SaO2 value from arterial blood samples obtained during the study.

排除标准
- •Subject is considered as being morbidly obese (defined as BMI large than 39.5).
- •Compromised circulation, injury, or physical malformation of fingers, toes, hands, ears or forehead/skull or other sensor sites which would limit the ability to test sites needed for the study.

结局指标
主要结局
Collect SpO2 data for accuracy statistical analysis by 11 subjects
时间窗: 3 days
Subjects were given medical grade mixtures of oxygen and nitrogen to induce stable plateaus across the range of 100% to 70%. The stable plateaus allowed data collection in the following SaO2 ranges 95-100, 90-95, 85-90, 80-85, 75-80, 67-75. In general, 4 to 8 discrete points were collected at each of the levels.
