*Measurement accuracy verification: The SpO
2
accuracy has been verified in human
experiments by comparing with arterial blood sample reference measured with a CO-oximeter.
Pulse oximeter measurements are statistically distributed and about two-thirds of the
measurements are expected to come within the specified accuracy range compared to
CO-oximeter measurements.

*Studies were performed to validate the accuracy of Pulse Oximeter with neonatal SpO
2
sensors by contrast with a CO-Oximeter. Some neonates aged from 1 day to 30 days with a
gestation age of 22 weeks to full term were involved in this study. The statistical analysis of
data of this study shows the accuracy (Arms) is within the stated accuracy specification. Please
see the following table.
