OBJECTIVE To analyze and compare lung function of obese and healthy, normal-weight children and adolescents, without asthma, through spirometry and volumetric capnography. METHODS Cross-sectional study including 77 subjects (38 obese) aged 5-17 years. All subjects underwent spirometry and volumetric capnography. The evaluations were repeated in obese subjects after the use of a bronchodilator...

OBJECTIVES Farming as an occupation is considered a risk factor for asthma and reduced lung function. By contrast, living on a farm during infancy has been reported to be associated with lower risk of asthma in adulthood. However, little is known about the association between farming environment during infancy and lung function in adulthood. We aimed to study the prospective longitudinal associ...

An electronic spirometer which utllizee a thermistor end an linearizing circuit, was evaluated. When compared to a Collins 13.5 liter water seal spirometer, 60 test results from 30 patienls revealed no clinically significant difference in forced vital capacity (FVC), forced expiratory volume in one second (FEVih or maximum voluntary ventilation (MVV). The device was found durable Pnd highly use...

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...

This study evaluated cardiopulmonary and metabolic responses to maximum exercise and aerobic capacity in hemiplegic patients and clarified the relationship between the resulting data and motor disability. Twenty patients with stroke and fifteen healthy controls were included in the study. Cardiopulmonary and metabolic responses to maximum exercise were investigated with an electronically braked...
