Table 2.1 - Ventilatory Function

Table 2.1 of the Approved Guide is in the following form:

“The major test of respiratory impairment is the ventilatory function test or respiratory test.  Predictive nomograms for the forced expiratory volume over one second (FEV 1) and the forced vital capacity (FVC) are at figures 2.1 (males) and 2.2 (females).”

NOTE:X-rays may be normal in any of the above categories. Measurement of FEV 1 and FVC should be performed with a vitalograph or equivalent instrument. Three readings should be taken and the best of these used to calculate impairment.
