accuracy has been verified in human experiments
by comparing with arterial blood sample reference measured with a CO-oximeter. Pulse
oximeter measurement are statistically distributed and about two-thirds of the measurements
are expected to come within the specified accuracy range compared to CO-oximeter
measurements.
