Measurement accuracy verification:
The SpO2 accuracy 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 ECG Signal 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.
