OBJECTIVE To evaluate the spirometry values predicted by the 2012 Global Lung Function Initiative (GLI) equations, which are recommended for international use, in comparison with those obtained for a sample of White adults used for the establishment of reference equations for spirometry in Brazil. METHODS The sample comprised 270 and 373 healthy males and females, respectively. The mean diffe...

BACKGROUND This study examined whether an increase in deep body temperature contributes to increases in ventilatory flow indicative of bronchodilatation. METHOD The study employed a within-participant repeated measures design. Nine participants (mean (SD): age 22 (3) years; height 177.7 (8.3) cm; mass 80.2 (19.1) kg) completed three conditions: exercise (EXERC; 30 min); 40°C water immersion (...

Blackhali, M. I. (1970). Archives of Disease in Childhood, 45, 363. Ventilatory function in subjects with childhood asthma who have become symptom free. Ventilatory function was studied in 12 males who suffered from asthma in childhood, but who had been free of symptoms for an average period of 11 years. Though resting levels of FEV1 and the FEV1/FVC ratio were in most cases normal, an abnormal...

The effects of particulate matter <10 microm in diameter (PM10) and other air pollutants on lung function were assessed in 975 schoolchildren, from eight communities in Lower Austria between 1994-1997. In each community, air pollution data were collected. Spirometry was performed twice a year. PM10 concentration (mean concentration between two subsequent lung-function measures in spring and aut...

background: postoperative pulmonary dysfunction is one of the most frequent complications after cardiac surgery and it is believed to result from the use of cardiopulmonary bypass (cpb). in this study, we investigated the effect of low tidal volume ventilation during cpb on postoperative gas exchange and lung mechanics. methods: this prospective randomized study included 100 patients undergoing...

there are evidences that statins have anti-inflammatory effects beyond their cholesterol lowering properties. the study was conducted to assess the effects of atorvastatin on asthma as an inflammatory disease. patients with moderate to severe asthma were entered this randomized, double blind, crossover clinical trial. the impact of oral atorvastatin (10 mg/day) on the lung function of normolipi...

The usefulness of peak expiratory flow monitoring is disputed because of the unreliability of written peak flow diaries. The aim of the present study was to examine the relationship of peak flow and forced expiratory volume in one second (FEV1) variation to other estimates of asthma severity in children, using an electronic home spirometer with automatic data storage. Over a 3-month period, 36 ...

Cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. However, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma. The purpose of this study was to determine the extent of change in ba...

[Purpose] This study compared the effects of Swiss ball exercise and resistance exercise on the respiratory function and trunk control ability of patients with scoliosis. [Subjects] Forty scoliosis patients were randomly divided into the Swiss ball exercise group (n= 20) and resistance exercise group (n = 20). [Methods] The Swiss ball and resistance exercise groups performed chest expansion and...

[Purpose] This study was aimed at assessing the effect of lumbar stabilization exercise on the pulmonary function of stroke patients. [Subjects and Methods] The subjects were randomly allocated into lumbar stabilization exercise group and a general physical therapy group. The program consisted of 30-min sessions conducted 3 days a week for 8 weeks. Pulmonary function was assessed based on lung ...
