·Clinical testing is a commonly used method for determining oxygen
saturation accuracy. The arterial hemoglobin oxygen saturation measured
with the device should be compared with the result of sampled arterial
blood analyzed with CO-oximeter.
·The name of the simulator used is Index2 FLUKE simulator, version
number: 3.0.0.
·Simulator is used for testing of consistency only; equipment
measurement accuracy is tested by clinical comparisons.
Possible causes
