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.

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.
