Measurement accuracy verification: The SpO
has been verified in human experiments by comparing with
arterial blood sample reference measured with a CO-
oximeter. The pulse rate accuracy has been verified by
Emulator. 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.
