This is often expressed as the ratio of FEV1/ FVC. Restrictive and Obstructive Lung Pathology- Background What do you think happens to the FEV1/FVC ratio in obstructive lung diseases, in restrictive lung disease? (yes I know this wasn’t in lecture– if you can figure this out yourself ...
Among the 5315 individuals evaluated, 260 (5.1%) had a restrictive spirometric diagnosis (forced vital capacity (FVC) < lower limit of normal (LLN) with forced expiratory volume in the first second to forced vital capacity ratio (FEV1/FVC) LLN; American Thoracic Society (ATS)/European ...
Results: The prevalence rate of obstructive pulmonary ventilation dysfunction (FEV1/FVC < 70%) was 2.3% in 2064 silica dust exposed workers. The prevalence of restrictive pulmonary ventilation dysfunction (FVC/Pre < 80%) was 8.1%. The prevalence of obstructive pulmonary ventilation dysfunction in ...

it should be notice that all the included COPD patients in this study turned out to be at GOLD stage III or IV (FEV1 < 50% predicted). For moderate to severe COPD [67,68], NPPV is a suitable and routine therapy, because of their impaired lung function, ventilatory restrictio,n ...
Similarly, restrictive lung conditions are characterized by a reduction of the functional volume of the lungs. Examples of restrictive lung conditions are sarcoidosis, pleural effusion, fibrosis, and alveolar effusion. Infectious lung conditions include tuberculosis, pneumonia, upper respiratory tract ...
