pite its description more than a decade ago by DISHyatt and associates,' the maximum eEort flowvolume (MEFV) loop has not been used widely in routine pulmonary function evaluation. Several studies have attested to its usefulness and have described qu

Subjects with severe chronic obstructive pulmonary disease (COPD) were studied to evaluate the effects of breathing retraining (BRT) on exercise tolerance. Twenty-two subjects exercised on a treadmill three times weekly for six weeks. Twelve of the s

Bronchomotor tone is, in part, under beta-adrenergic control, and beta-adrenergic agonists are commonly used in the therapy for chronic obstructive pulmonary disease (COPD). Beta-adrenergic blockade with propranolol is contraindicated in asthmatic pa

Twenty-eight men with the Pi MZ phenotype who have been employed in the Saskatchewan country grain elevators and thus regularly exposed to high levels of grain dust, were case matched for age, years of employment, employment status, smoking status, a

Differences in the shape of the maximum expiratory flow volume (MEFV) curve have been associated with pathologic states and physiologic differences between normal individuals. We describe variations in a new parameter, angle p, which characterizes th

Results of a cross-sectional study of ventilatory lung function (VLF) in a group of 307 working men showed that the leukocyte count in peripheral blood is more closely associated with the relative position (percentile) of a person in the frequency di

The purpose of this project was to better define factors that influence the resting FaCO 2 and the change in the FaCO 2 from rest to exercise in patients with moderate to severe chronic airflow obstruction. Pulmonary function testing, symptom-limited

We studied 20 men (ages 46 to 69, mean 45 years) with chronic obstructive pulmonary disease (FEV1 of 0.55 to 2.1 L), to determine the relative importance of pulmonary impairment vs other occult physical or psychologic factors in the genesis of sexual

In 84 subjects with varying degrees of chronic airflow limitation (CAL), airways responsiveness (AR) measured by the response to an inhaled bronchodilator was negatively correlated with pulmonary function. Correlation coefficients were AR and FEV1, r
