rSO2 accuracy testing was conducted during induced hypoxia studies on healthy, nonsmoking, light- to dark-skinned subjects in an independent research laboratory. The measured regional hemoglobin saturation value (rSO2) of the sensors was compared to arterial/venous hemoglobin oxygen (SavO2) value, determined from venous and arterial blood samples. The model used for blood in the brain was 70% venous and 30% arterial, which is applicable under normocapnic conditions. The venous blood was drawn from the right jugular bulb. The accuracy of the sensors in comparison to the blood gas analyzer samples measured over the rSO2 range of 45–100%. Accuracy data was calculated using the root-mean-squared (Arms value) for all subjects, per ISO 80601-2-61:2011, Medical Electrical Equipment—Particular requirements for basic safety and essential performance of pulse oximeter equipment.
