Notes:
1) The claim for oxygen saturation accuracy should be supported by clinical studies
covering the entire claimed range,The fraction of inspired oxygen (FiO2) delivered to
test subjects is varied to achieve a series of targeted steady-state saturation periods
over the specified SpO2 accuracy range (e.g. 70 % to 100 % ),then the SpO2 accuracy
is calculated by comparing SpO2 readings of the pulse oximeter to the values of
SpO2 determined with a Co- Oximeter.
