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 within the specified accuracy range compared to CO- oximeter measurements.
The accuracy of the oximeter has been validated by a clinical trial involving 12 healthy adult subjects - 4 women and 8
men. Among them medium skin are 4 subjects, light skin are 5 subjects, dark skin are 3 subjects, the age from 21 to
28.
Overall accuracy was determined by calculating the root mean square error across all samples and is 1.56%”.
