Neonatal accuracy specifications are based upon testing the N-3000 and N-25 neonatal
sensors on healthy adult volunteers in induced hypoxia studies, in the range of 70-100%
SpO . The specified accuracy also takes into account published literature which predicts
2
that there may be a small difference in % SpO
ments from adult and fetal blood with 100% fetal hemoglobin are compared. Fetal
hemoglobin is present in concentrations varying from 10% to 90% in neonatal blood,
and this percentage declines over time. As the percentage of fetal hemoglobin in neonatal
blood declines, the theoretical effect on accuracy due to this source is reduced".
