The present study elucidates the effect of undernutrition on pulmonary functions in children. The study was carried out in healthy normals, wasted, wasted and stunted children. Spirometry was performed with Vitalograph Compact-II spirometer. Wasted, wasted and stunted children showed lower lung volumes, forced mid expiratory flow time and inspiratory flow rates than healthy normals. Wasted and ...

Excessive variability in spirometric measurements derived from the forced expiratory volume manoeuvre , also called "test failure,"' is a phenomenon familiar to all those who use pulmonary function tests, whether it be in a clinical context2 or in the context of population based studies.3 Because the manoeuvre is effort dependent, test failure is usually attributed to a failure of effort or com...

obesity as a common health risk is increasing all over the world. the aim of this study was evaluation of standing and sitting positions on spirometric values in obese asthmatic patients, in comparison with normal obese subjects. the study included 49 obese asthmatic patients with mean age of 42.63 years and body mass index of 36.06 kg/m 2 , and 51 control obese normal subjects with mean age of...

The present study was undertaken to determine if beta-agonists delivered by nebulizer provide better clinical responses than MDI therapy in status asthmaticus. We divided 28 hospitalized asthmatic patients into three groups. Group 1 received albuterol by MDI with InspirEase. Group 2 received nebulized albuterol. Group 3 received nebulized metaproterenol. Both nebulizer regimens resulted in sign...

BACKGROUND The purpose of this study was to examine changes in the airway lumen and parenchyma in relation to lung function in patients with chronic obstructive pulmonary disease (COPD) compared with controls. METHODS We studied 70 patients with COPD and 15 normal subjects. Using reconstructed computed tomography (CT) images, we traced the bronchial trees and reconstructed 3 cm circle images ...

OBJECTIVES To compare the clinical diagnosis of chronic obstructive pulmonary disease (COPD) with results of post-bronchodilator spirometry in general practice, and examine practitioner, practice and patient characteristics associated with agreement between clinical and spirometric diagnoses. DESIGN, SETTING AND PARTICIPANTS General practitioners from practices in Sydney identified eligible p...

Spirometric studies and arterial blood gas analyses were statistically evaluated in 75 patients with chronic airways obstruction to determine whether any spirometric parameters can predict arterial blood gas status. Radioactive lung scans, both ventilation (using '33Xe gas) and perfusion (using '31-MAA), were performed in selected patients. In all 75 patients as one group, no spirometric parame...
