In this issue of Chest The loss of elastic recoil in lung tissue and the increased airway resistance decrease the expiratory airflow in a patient with chronic obstructive pulmonary disease as compared with the expiratory airflow in a normal subject. or in obstructive lung disease RV appears to be determined by a flow.iii Do obstructive and restrictive lung diseases share some common underlying. Recoil and hyperinflation in COPD versus increased elastic recoil and volume.Distinguish the types of In some obstructive lung Dzs say emphysema (congenital or acquired), u basically have more elastase activity than anti-elastase activity thus the interstitium is broken down thus decreasing the # of elastic springs b/t the airway lumen & interstitium, aka reduced elastic recoil. 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 Obstructive lung diseases, particularly emphysema, result in an increase in the RV and RV-to-TLC ratio. In severe emphysema, particularly bullous emphysema, the TLC can show a marked increase. Pale, voluminous lungs • Centriacinar emphysema Less impressive changes Deeper pink and less voluminous lungs.

Proteoglycans, collagen, and elastic fibers and their interrelationships are in diseases such as atherosclerosis, emphysema, and pulmonary fibrosis. alveolar attachments Decrease of elastic recoil AIRFLOW LIMITATION 62 The association of heart diseases with COPD and restrictive lung C21, currently in clinical trials for the treatment of idiopathic pulmonary fibrosis. time-of-flight elastic recoil detection analysis and nuclear reaction analysis to For nonneoplastic diseases (chronic obstructive pulmonary disorder and idiopathic pulmonary fibrosis), CgA was elevated in 26-37%.
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.

DM being a systemic disease, which also affects lungs causing restrictive type of tissues, reduced pulmonary elastic recoil and inflammatory changes in lungs.

With inhalation, the intrapleural pressure (the pressure within the pleural cavity) of the lungs decreases. (C) Restrictive disorder (eg, interstitial lung disease, kyphoscoliosis). The loop is narrowed because of diminished lung volumes. Airflow is greater than normal at comparable lung volumes because the increased elastic recoil of lungs holds the airways open. (D) Fixed obstruction of the upper airway (eg, tracheal stenosis, goiter).
Elastic Recoil and Compliance LUNG COMPLIANCE is defined as the stretchability of the lung for any 1-cm change in
Compliance is inversely related to the elastic recoil of the lungs, so thickening of lung tissue will decrease lung compliance. The lungs must also be able to overcome the force of surface tension from water on lung tissue during inflation in order to be compliant, and greater surface tension causes lower lung compliance.
