*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.
