Accuracy Testing
SpO
2
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 (SpO
2
) of the sensors
is compared to arterial hemoglobin oxygen (SaO
2
) 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 SpO
2
range of 70 – 100%. Accuracy data is calculated using the root-mean-
squared (A
rms
value) for all subjects, per ISO 80601-2-61, Standard Specification for Pulse
Oximeters for Accuracy.
