The Sunrise SpO2 and Pulse Rate Accuracy Validation Study

Subjects will be given medical grade mixtures of oxygen and nitrogen to induce stable plateaus across the range of 100% to 70% SaO2. When the reference system's blood saturation stabilizes at an acceptable plateau level, blood sampling can start. Four to eight arterial blood samples will be collected for each plateau, while keeping at least 20 seconds in between each sample and at least 30 seconds once the plateau has been reached. The blood will be immediately analyzed by the reference CO-Oximeter to measure the arterial oxygen saturation (Functional SaO2). SpO2 values from the Sunrise sensor 2 will be collected electronically simultaneously to blood drawn from the indwelling catheter. Data will be collected under non-motion conditions. The pulse rate will be simultaneously collected over the SpO2 range covered. The reference method for the computation of pulse rate accuracy will be an ECG heart rate. The total duration of the test will be about 1 hour per subject. Data analysis results will provide documentation showing SpO2 and pulse rate accuracy performance of the Sunrise sensor 2 as compared to arterial blood samples measured by Reference CO-Oximetry and to ECG heart rate, respectively.
