A previous study using spirometric methods demonstrated that 42% of subjects with tetraplegia experienced significant bronchodilation following inhalation of metaproterenol sulfate (MS). Comparative studies involving subjects with paraplegia were not performed and none has been performed in this population using body plethysmography, a more sensitive method used to assess airway responsiveness....

The effects of an upper respiratory infection on some commonly measured spirometric indices have been determined in this study. The forcod vital capacity, forced expiratory volume in one second, forced expiratory flow in the middle half of the vital capacity and the peak expiratory flow were significantly lower during the infection. This stresses the need in cross sectional and longitudinal pul...

Abstract Background Nasal obstruction is a significant medical problem. This study aimed to examine the effect of nasal and packing on arterial blood gases pulmonary function indices, impact elimination preoperative values. Results The mean age population was 26.6 ± 10.1 years, males represented 50.8%. Spirometric indices showed statistically improvement (preoperative forced expiratory volume i...

Objective: To investigate the validity of spirometric tests performed in general practice. Method: A repeated within subject comparison of spirometric tests with a ‘‘gold standard’’ (spirometric tests performed in a pulmonary function laboratory) was performed in 388 subjects with chronic obstructive pulmonary disease (COPD) from 61 general practices and four laboratories. General practitioners...

background welding is defined as linking two metals with a local conjunction in sufficient thermal, pressing and metallurgical condition. there are several methods for linking two metals in welding. objectives welding is one of the professional jobs in iran, yet there have not been considerable studies on its harmful effects. the current study aimed to compare lung functional tests between weld...

BACKGROUND Asthma, traditionally characterized as reversible airway obstruction, might lead to structural changes and permanent impairment. OBJECTIVE We sought to study the frequency, severity, and reversibility of pulmonary deficits in adults with a history of moderate-to-severe childhood allergic asthma. METHODS Subjects (n = 121) previously enrolled in a randomized trial of immunotherapy...
