Which lung volume increases with exercise? Tidal Volume 2. What is the purpose of performing a PFT? Helps to diagnose any COPDs or restrictive pulmonary diseases 3. What variables (FVC, FEV 1.0 , etc.) should be affected by obstructive and restrictive pulmonary disease and why? Based on the data you collected, were your simulations consistent with these effects? Explain. FVC and FEV 1.0 are affected by obstructive and restrictive pulmonary disease because obstructive is like breathing through a straw, so it is much harder to get air out. RV and
