NOTE
•
A functional tester or SpO
2
simulator can be used to determine the pulse
rate accuracy.

*SpO
2
accuracy was determined by testing on healthy adult volunteers in the range of 60% to 100% SpO
2
against a laboratory CO-Oximeter. SpO
2
accuracy was determined on 16 neonatal NICU patients ranging in age
from 7-135 days old and weighing between 0.5-4.25 kg. Seventy-nine (79) data samples were collected over
range of 70-100% SaO
2
with a resultant accuracy of 2.9% SpO
2
.
The following table shows the accuracy (A
rms
) for the SpO
2
sensors in four kinds of SaO
2
ranges. For the Fitting
Curve of the SpO
2
sensors, refer to the "Fitting Curve for Masimo SpO2 Sensors" on page A - 15 .
