Declared Accuracy*: The table below shows Arms values measured using the Model 9591 in non-motion conditions.

Range Specified Oxygen Saturation (Arms) Finger Oxygen Saturation (Arms) 95% Limits of Agreement Low Perfusion Oxygen Saturation (Arms)
70 – 100% ±2 ± 1.31 (-2.3 – 2.9) ±2
70 – 80% ±2 ± 1.62 (-1.7 – 3.7) ±2
80 – 90% ±2 ± 1.05 (-2.3 – 2.2) ±2
90 – 100% ±2 ± 1.18 (-2.4 – 2.4) ±2


This graph shows plots of the error (SpO2 – SaO2) by SaO2 using the Model 9591 with a linear regression fit and upper 95% and lower 95% limits of agreement. Each sample data point is identified by subject from a clinical study in non-motion.
