increases in body mass index (bmi) are reported to influence asthma response to treatment. the aim of this study was to investigate the relationship between bmi and response to treatment in a group of patients that were referred for asthma control. effectiveness measurements in this analysis included percentage of changes in forced volume in 1 second (fev1), forced volume capacity (fvc), fev1/f...

Forced expiratory flow (FEF) rates were determined for 170 (130 males and 40 females) healthy adults of Himachal Pradesh in the age group of 19-26 years for males and 19-22 years for females. The subjects had been staying at an altitude of 2150 M above mean sea level (MSL) for at least three years prior to the conduct of the study. FEF200-1200, FEF25-75% and FEF75-85% were found to be high as c...

Results Data comprised 14 males, 35 females, mean age 54yrs (31-72), 82 % never-smokers. 44 had post bronchodilator studies. FEF75 or FEF25-75 < 65% were categorised as SAW disease. Pre bronchodilator (Pre-BD) Mean FEV1/ FVC was 78% (70-91%), however Mean FEF75 and FEF25-75 (% predicted) were 34.5% and 43.3% respectively. 6 patients had both, a reversibility in FEV1 >12% and increase by 200ml. ...

Spirometric volumes and expiratory flows were measured among 448 Senegalese males and females of 25-80 yrs of age. The values obtained are similar to those reported for black Africans and black Americans in the literature. Volumes are 15-25% lower in males and 23% lower in females than in Caucasians. Forced expiratory flow between 25-75% of vital capacity (VC), (FEF25-75) is 5-18% lower in male...

Background Spirometry is widely regarded as a clinically invaluable measurement method that is of genuine recommend for the diagnosis and management of asthmatic patients. FEV-1 and FEV1/FVC are vastly perceived as asthma severity and control assessment indices, according to the present clinical guidelines. Since FEV-1 index is chiefly within normal ranges even in the most severe cases, the cer...

After two hours of abstinence from smoking pulmonary functions were assessed in twenty-seven asymptomatic male smokers by spirometry and Wright Peak Flow Meter, recording FVC, FEV1, FEV1%, FEF25-75%, and FEF75-85% of FVC, MVV and PEFR. These tests were repeated immediately after smoking and again after one hr. Only PEFR decreased significantly (P less than 0.01) and returned to nearly basal lev...

OBJECTIVE To determine whether alterations in pulmonary function takes place in subclinical hypothyroidism by examining the diffusion lung capacity and muscle strength of such patients. METHODS This is a descriptive study conducted in 2009 at Haseki Training and Research Hospital, Istanbul, Turkey. Hundred and twenty-six patients with subclinical hypothyroidism and 58 age and sex matched indi...

This cross-sectional study was conducted in 1992 in the oldest of three Portland cement producing factories in Eastern Saudi Arabia. The respirable dust level was in excess of the recommended ACGIH level in all sections. Spirometry was done for 149 cement workers and 348 controls, using a Vitalograph spirometer. FEV1, FVC, FEV1/FVC% and FEF25-75% were calculated and corrected to BTPS. A signifi...

BACKGROUND Pulmonary complications remain a leading cause of morbidity after major abdominal operations. OBJECTIVE To compare pulmonary function and the frequency of pulmonary complications after laparoscopic cholecystectomy (LC) and open cholecystectomy (OC). METHODS Fifty-five patients with symptomatic gallstone disease undergoing elective cholecystectomy (LC 40, OC 15) under general anes...

OBJECTIVE Post-infectious bronchiolitis obliterans (PIBO) is a clinical entity that has been classified as constrictive, fixed obstruction of the lumen by fibrotic tissue. However, recent studies using impulse oscillometry have reported bronchodilator responses in PIBO patients. The objective of this study was to evaluate bronchodilator responses in pediatric PIBO patients, comparing different ...
