BACKGROUND Expiratory flow limitation (EFL) is seen in some patients presenting with a COPD exacerbation; however, it is unclear how EFL relates to the clinical features of the exacerbation. We hypothesized that EFL when present contributes to symptoms and duration of recovery during a COPD exacerbation. Our aim was to compare changes in EFL with symptoms in subjects with and without flow-limit...

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...

[Purpose] The purpose of this study was to identify changes in pulmonary function and pulmonary strength according to time of day. [Subjects and Methods] The subjects were 20 healthy adults who had no cardiopulmonary-related diseases. Pulmonary function and pulmonary strength tests were performed on the same subjects at 9:00 am, 1:00 pm, and 5:00 pm. The pulmonary function tests included forced...

We used meta-analysis to measure the effect of high-altitude climate therapy (HACT) on lung function outcomes in asthma, and systematically searched PubMed, Embase and www.elibrary.ru for publications appearing from 1970 to mid-2015. We included studies carried out with children or adults with an exposure of up to 12 weeks at an altitude of ≥1500 m above sea level. Changes in forced expiratory ...

[Purpose] The objective of this study was to determine the effect of thoracic joint mobilization and self-stretching exercise on the pulmonary functions of patients with chronic neck pain. [Subjects] The present study was performed with 34 patients with chronic neck pain featuring thoracic kyphosis; we divided them into a thoracic joint mobilization group (TJMG, n = 11), self-stretching exercis...

CONTEXT Although decline in lung function across workshift has been observed in wildland firefighters, measurements have been restricted to days when they worked at fires. Consequently, such results could have been confounded by normal circadian variation associated with lung function. OBJECTIVES We investigated the across-shift changes in lung function of wildland firefighters, and the effec...

BACKGROUND & OBJECTIVES Spirometry plays an important role in the assessment and long term monitoring of patients with asthma. Difficulty in performing spirometry in children has resulted in a paucity of Indian studies using spirometry regularly for research in the paediatric population. This study was undertaken to assess the clinical improvement and changes in spirometric measurements with tr...

The forced vital capacity, forced expiratory volume in one second, peak expiratory flow, mid-expiratory flow and maximum voluntary ventilation was measured in 632 healthy, normal children from Metropolitan city of Bombay using computerized spirometer. The children were between age range 6 years to 15 years and belong to high or middle and lower socio economic status. The pulmonary function data...
