Module
*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 with in the specified accuracy range compared to CO-oximeter measurements.
Measurement range 0 to 100 %
Resolution 1 %
Accuracy 70 % to 100 %: ± 2 % (measured without motion in adult/pediatric
mode)
0 % to 69 %: Not specified.
Data update period ≤30 s
*Studies were performed to validate the accuracy of Pulse Oximeter with SpO
2
sensors by contrast
with a CO-Oximeter. The statistical analysis of data of this study shows the accuracy (Arms) is
within the stated accuracy specification. Please see the following table.
