3 Static lung volumes IC

4 Slow (SVC) and forced (FVC) vital capacity in
health and disease

5 Asthma (55 year, female) FVC: 2.4 (73 ref%) – 3.1 (92 ref%)
FEV1: 1.0 (36 ref%) – 1.5 (52 ref%) FEV1/FVC: 42% - 49%

6 COPD = postbronchodilator FEV1/FVC<70%

7 Mild lung fibrosis (53 year, male)
FVC: 92 ref% TLC: 85 ref% FEV1: 89 ref% RV: 83 ref% FEV1/FVC: 77% DLCO: 52 ref%

8 Severe fibrosis (62 year, female)
FVC: 75 ref% TLC: 63 ref% FEV1: 78 ref% RV: 57 ref% FEV1/FVC: 87% DLCO: 34 ref%

9 Heart failure (83 year, female)
FVC: 55 ref% FEV1: 49 ref% FEV1/FVC: 74%
