Restriction of expansion of the lungs or chest wall impedes inflation of the lungs during inhalation. Functional changes occurring during such restriction include reduced pulmonary and/or chest wall compliance, decreases in pulmonary function, and ultimately a decrease in exercise performance. Such restriction can be seen in several pathologic conditions such as scoliosis or obesity, as well as...

Various investigators have addressed the minimum lung function required to activate breathalyzers, and the impact of comorbid respiratory illness. We postulated that subjects with significant chest trauma may have difficulty in providing an adequate breathalyzer sample. A prospective self-controlled study of 20 patients who underwent thoracotomy was conducted between August 2005 and December 20...

Regular exercise has proved to be beneficial for the human body and the lungs are no exception. The present study was undertaken to assess the relation between the quality of exercise performed and the quantitative effect of these exercises on the lungs. Pulmonary function tests of sportsmen engaged in various sports were compared with each other and with that of the controls. Players playing f...
