Accuracy – Sensors: Declared accuracy data for compatible sensors can be found in Nonin’s Sensor Accuracy document.

*This information is especially useful for clinicians performing photodynamic therapy.

SpO₂ Accuracy Testing
SpO₂ accuracy testing is conducted during induced hypoxia studies on healthy, non-smoking, light-to-dark-skinned subjects during motion and no-motion conditions in an independent research laboratory. The measured arterial hemoglobin saturation value (SpO₂) of the sensors is compared to arterial hemoglobin oxygen (SaO₂) value, determined from blood samples with a laboratory co-oximeter. The accuracy of the sensors in comparison to the co-oximeter samples measured over the SpO₂ range of 70 – 100%. Accuracy data is calculated using the root-meansquared (Arms value) for all subjects, per ISO 80601-2-61, Standard Specification for Pulse Oximeters for Accuracy.
