Performance Specifications
*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%
Sp02. The specified accuracy also takes into account published literature which predicts
that there may be small difference in % Sp0
2
reported by the Oximetry when measurements
from adult and fetal blood 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.
