II.ARDS
III.Skeletal deformities
IV.Asthma

Question

Quizplus · Accepted Answer

Fibrotic lung diseases increase lung elastic recoil, shrinking all volumes and capacities. Increased alveolar-capillary membrane permeability, characteristic of acute respiratory distress syndrome (ARDS), disrupts surfactant synthesis and increases alveolar surface tension. This decreases FRC and RV by causing widespread alveolar collapse. Extrapulmonary restriction of lung expAnswerion by skeletal deformities also reduces all lung volumes and capacities. Regardless of the mechanisms involved, reduced FRC and high lung recoil increase the work of breathing. Diseases decreasing FRC and RV are generally classified as restrictive.
