Cigarette smoking: Cigarette smoke is by far the most common cause of emphysema lasix 40 meq. The damage begins when tobacco smoke temporarily paralyzes the microscopic hairs (cilia) that line the bronchi. Typically, these hairs sweep irritants and germs from the respiratory tract.
But when smoke interferes with this broad movement, irritants remain in the bronchi and penetrate into the alveoli, inflaming the tissue and eventually the destruction of elastic fibers. Difficulty breathing (dyspnea) due to light for too high trying to get more oxygen to the tissues. .
