be at risk of COPD at the presymptomatic stage. This “screening”
or “case selection” for full spirometry examinations may result in
earlier medical intervention and facilitate better clinical outcomes.
The device displays some key parameters for clinical interpretation:
• FEV1 and FEV1 % Predicted
• FEV6 and FEV6 % Predicted
• FEV1/FEV6 and FEV1/FEV6 % Predicted
If an abnormal result is indicated, arrows on the display show:
• Obstructive Index
• COPD Classication (stages I - IV)
