* One percent was added to the accuracies for neonatal sensors to account for accuracy variation due to properties of fetal
hemoglobin. 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.
Sensor type Totally neonates Data Arms
