Reproducibility of flow rates measured with low density gas mixtures in exercise-induced bronchospasm.
We have studied the reproducibility of the change in maximum expiratory flow rates after breathing helium/oxygen (He/O2) mixtures in 12 asthmatics at rest and after exercise. Each subject performed four identical exercise tests which caused a similar degree of exercise-induced bronchospasm (EIB) on each occasion. We compared flow rates at 50% of the vital capacity (V50) breathing He/O2 to those...

CONTEXT Exercise-induced bronchospasm (EIB) is a phenomenon of airway narrowing that occurs during or after exercise or physical exertion. This condition has been reported in a range of sporting activities but is most common in participants of cold-weather sports (eg, Nordic skiing) and indoor sports (eg, ice-skating and swimming). Traditionally, the terms exercise induced-asthma (EIA) and EIB ...
متن کاملExercise-induced bronchospasm in children.
This review will encompass definition, history, epidemiology, pathogenesis, diagnosis, and management of exercise -induced bronchospasm in the pediatric individual with and without known asthma. Exercise induced asthma is the conventional term for transient airway narrowing in a known asthma in association with strenuous exercise usually lasting 5-10 minutes with a decline in pulmonary function...
متن کاملExercise-induced bronchospasm at low temperature in elite runners.
BACKGROUND Healthy elite runners often report bronchial symptoms when training in subzero temperatures. The occurrence and causes of exercise-induced bronchospasm after heavy exercise in cold air were investigated in elite runners. METHODS Thirty two non-asthmatic runners, mostly from Finnish national teams, volunteered to take part in the study. They answered a questionnaire and were subject...
