Meet standards of ISO 80601-2-61
*Measurement accuracy verification: The SpO

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.
