If a ventilatory pattern is identified, its severity is graded. The American Thoracic Society has developed a scale to rate the severity of disease based on predicted FEV1 and TLC.29. The practical implication of these findings is that the “normal range” for FVC or FEV 1 is considerably wider than the frequently quoted 80–120% pred both for young children and for subjects aged >30 yrs. The test session is finished when the difference between the two largest FVC measurements and between the two largest FEV1 measurements is within 0.2 L.
