WebPulmonology. Restrictive lung diseases are a category of extrapulmonary, pleural, or parenchymal respiratory diseases that restrict lung expansion, [2] resulting in a decreased lung volume, an increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function test demonstrates a decrease in the forced vital capacity. WebDec 5, 2024 · Work of breathing in a normal lung (left) compared to a lung with restrictive pulmonary disease (right): Because its compliance is decreased, the restrictive lung requires more negative pressure to be inflated, thereby increasing the amount of work needed to breathe.
