WebMay 17, 2024 · The methodology was qualified with a precision of 8.5% and mean bias of 3.6%. The robustness data generated during execution of the design of experiment generated a precision and accuracy/bias similar to the qualification data. Statistical analysis demonstrated the methodology to be robust with regard to assay factors tested. WebMean bias relative to the sum of oxy-, carboxy-, and methemoglobins ranged from -0.4 to -2.6 percent for the pulse oximeters and +1.8 to -4.2 percent for the conventional oximeters. Two pulse oximeters performed well at all saturations down to 65 percent, while the others showed either increasing or decreasing bias below 80 percent saturation.
