Chronic bronchitis

Other disorders of the lower respiratory tract include emphysema (lung disorder in which the terminal bronchioles or alveoli become enlarged and plugged with mucus) and chronic bronchitis (chronic inflammation and possibly infection of die bronchi). Chronic obstructive pulmonary disease (COPD) is die name given collectively to emphysema and chronic bronchitis because die obstruction to die airflow is present most of the time. Asdima diat is persistent and present for most of die time may also be referred to as COPD.

Most subjects made complete recovery. 9 subjects had long-term effects, such as pulmonary tuberculosis, bronchitis, chronic adhesive pleurisy. 

Lower respiratory disorders are conditions that obstruct or restrict tracheobronchial tubes, preventing exchange of gases. These conditions are called chronic obstructive pulmonary disease (COPD), and include bronchitis, chronic bronchitis, bronchiectasis, emphysema, asthma, and chronic asthma. 

Acetylcysteine decreases thickness of mucous secretions in lung. As a mucolytic agent, acetylcysteine splits disulfide linkages between mucoprotein molecular complexes, decreasing their viscosity. It is used as an adjunct therapy in emphysema with bronchitis, chronic asthmatic bronchitis, mberculosis, bronchiectasis, primary amyloidosis of the lung, pneumonia, and tracheobronchitis. In addition, it is used in pulmonary complications of cystic fibrosis and those associated with anesthetics, surgery, or care following tracheostomy. 

Polluted urban air can and has aggravated chronic bronchitis, chronic obstructive ventilatory disease, pulmonary emphysema, and bronchial asthma [11]. The incidence of pulmonary tuberculosis is high in the major cities of India, and air pollution can retard recovery despite adequate therapy. A study of 130 traffic constables, 60 bus drivers and 20 auto mechanics in Madras, who constantly inhaled lead polluted air, recorded that these people had a high frequency of respiratory abnormalities. 61.38% of the bus drivers.
