Calibrating the M-50 series Pulse Oximeter Sensor

The functional tester cannot be used to assess the accuracy of the Oximeter.

Index2 that made by Bioteck company is a function tester. The user can use this function tester to measure the Oximeter.

The test methods used to establish the SpO2 accuracy is clinical testing. The Oximeter used to measure the arterial haemoglobin oxygen saturation levels and these levels are to be compared to the levels determined form arterial blood sampling with a CO-Oximeter.
