Chronic obstructive pulmonary disease in over 16s: diagnosis and management
Continuous or nocturnal oxygen therapy in hypoxemic chronic obstructive lung disease: Subsequent studies of acute and chronic oxygen therapy in patients with COPD also failed to show resolution of PH Lejeune et al ; Timms et al Echocardiography is the principle noninvasive diagnostic test but may be technically limited in a significant proportion of patients with COPD.
The degree of intimal thickening correlates with the severity of small airways disease and emphysema Hale et al Being either underweight or overweight can affect the symptoms, degree of disability, and prognosis of COPD. Lung disease in long-term cigarette smokers with and without chronic air-flow obstruction. Colas des Francs, A.
Toxic effects of cigarette smoke Tobacco smoke is not only epof to the airways and lung parenchyma but also has an effect on the pulmonary vasculature and may play a significant role in the development of PH.
The combined action of hypoxemia, toxic tobacco smoke, pulmonary dysfunction, and polycythemia lead to endothelial dysfunction, growth factor production, and inflammation in the pulmonary vasculature.
Fishman’s Pulmonary Diseases and Disorders 4th ed. Overexpression of prostacyclin synthase inhibits growth of vascular smooth muscle cells. The characteristic chest radiographic findings of PH are enlargement of the central pulmonary arteries causing hilar prominence and rapid tapering of the arteries in the lung periphery. Problems playing this file? The small pulmonary arteries of smokers develop intimal thickening due to elastin deposition, increased collagen production, and smooth muscle proliferation regardless of the development of obstructive lung disease Santos et al ; Hale et al Excessive oxygen; however, can result in increased CO 2 levels and a decreased level of consciousness.
