Imbalance between the inward and outward elastic recoil can cause restrictive lung disease: Intrinsic lung disease → lung volume is decreased due to excessive increase in the lung’s elastic recoil compared with chest wall elastic recoil. Pleural and thoracic cage disorders→ total decrease in lung’s compliance leading to reduction in total

Elastin is expressed in most tissues that require elastic recoil. The protein first appeared coincident with the closed circulatory system, and was critical for the evolutionary success of the vertebrate lineage. Elastin is expressed by multiple cell types in the lung, including mesothelial cells in … How lung volumes are changed in restrictive lung diseases? 1) Residual volume (RV) decreases due to an increased elastic recoil 2) Total lung capacity (TLC) decreases because of low RV and low VC (reduced compliance) 3) Forced vital capacity (FVC) moderately decreases because of extensive parenchymal fibrosis and preserved airway conductivity The physiological effects of diffuse parenchyma disorders —- reduce all lung volumes by the excessive elastic recoil of the lungs, in comparison to the outward recoil forces of the chest wall —- expiratory airflow is reduced in proportion to lung volume —- arterial hypoxemia in these disorders is primarily caused by ventilation-perfusion mismatch —- the diffusion of oxygen is impaired —- hypoxemia 2021-02-08 · Elastic recoil is the tendency of the lungs to recover as people breathe in and out. When people inhale, their lungs fill rapidly with air. Surfactant , a lubricant in the lungs, changes the surface tension in the lungs and allows the alveoli, tiny bubble-like structures lining the lungs, to expand.

In these types of restrictive diseases, the intrapleural pressure is more positive and the airways collapse upon exhalation, which traps air in the lungs. Forced or functional vital capacity (FVC) , which is the amount of air that can be forcibly exhaled after taking the deepest breath possible, is much lower than in normal patients, and the time it takes to exhale most of the air is greatly

Thin walls means need little pressure to inflate, but since elastic recoil is low expiration is difficult (air is left behind as a result, hyperinflation). (C) Restrictive disorder (eg, interstitial lung disease, kyphoscoliosis).

PathophysiologyIntrinsic lung diseases:s Diffuse parenchymal disorders cause reduction in all lung volumes.s This is produced by excessive elastic recoil of the lungs.s Expiratory flows are reduced in proportion to lung volumes.s Arterial hypoxemia is caused by ventilation/perfusion mismatch.s Impaired diffusion of oxygen will cause exercise- induced desaturation.s Hyperventilation at rest secondary to reflex stimulation.

Flow rates are greater than normal at comparable lung volumes because the elastic recoil of lungs holds the airways open. normal maximum static pulmonary recoil pressure (Pmax). Since in pulmonary restrictive disease, the Pmax was found to be elevated, it was a useful test for distinguishing pulmonary restrictiw from pleural re- striction. The Pmax is a measure of the elastic recoil force of the lung at total lung capacity. It is decreased in emphysema. The decreased lung elastic recoil reduced the increase of elastic work of breathing produced by the hyperinflation. There was no statistically significant change in lung elastic recoil from static deflation pressure-volume (P-V) curves from total lung capacity (TLC).

TLC occurs when the forces of inspiration decrease because of chest wall muscle lengthening and are insufficient to overcome the increasing force required to distend the lung and chest wall (see Fig. 2.4 ). A 19-year-old woman presented with lifelong asthma.

In general, elastic recoil is increased in a restrictive ventilatory defect associated with decreased lung volumes. Conversely, in almost all forms of airflow obstruction, elastic recoil is decreased. It was found that flow rates were reduced in such patients because of the combined effects of reduced elastic recoil (transpulmonary pressure) and intrinsic diseases of the airways.
