Running, walking, and hyperventilation causing asthma in children.

چکیده
To examine further the relation between type of exercise, workload, ventilation, and exercise-induced asthma, we compared treadmill walking with treadmill running and treadmill running with isocapnic hyperventilation in separate studies in children and adolescents. Inspired air conditions were identical during each pair of tests. Walking and running with similar minute ventilation and oxygen consumption were followed by similar falls in peak expiratory flow rate as were running and hyperventilation with similar minute ventilation and end-tidal carbon dioxide tension. This study supports the concept that hyperventilation is a central mechanism in exercise-induced asthma.

Background & Aims: Hyperventilation is the most common breathing pattern disorder. Several studies indicate that hyperventilation is common in asthmatic patients. There has been no study on prevalence of hyperventilation syndrome in Iran so far. This study aimed to evaluate the prevalence of hyperventilation syndrome in asthmatic patients. Materials & Methods: This cross-sectional study was ...
متن کاملAn unusual example of exercise-induced asthma.
A patient with exercise-induced asthma is described in whom the post-exercise fall in F.E.V.1 was not prevented by the inhalation of isoprenaline immediately before exercise but was almost completely prevented by subcutaneous atropine given 40 minutes before exercise. A large fall in F.E.V.1 similar to the fall after exercise occurred after carbon dioxide-induced hyperventilation and voluntary ...

To compare the refractory period that follows exercise and isocapnic hyperventilation, 10 asthmatic children performed two pairs of challenge tests in random order at least six hours apart. In pair A a hyperventilation challenge was followed by an exercise challenge and in pair B the order was reversed. Both pairs of tests were done while the children were breathing cold dry air. Tests were mat...

Background: Intracranial pressure (ICP) control is one of the anesthesiologist challenges in craniosynostosis repair surgery, especially in multiple sutures involvement. The aim of this study was comparing the effect of two anesthesia methods including inhalation with hyperventilation and total intravenous anesthesia (TIVA) on ICP control and surgeon satisfaction in pediatrics with craniosynost...

Isocapnic hyperventilation dose response curves were constructed for 11 asthmatic children before and after pretreatment with placebo or ipratropium bromide, 40-1500 micrograms given by inhalation, on three separate days. The response before and after placebo was highly reproducible (within subject coefficient of variation 7.5%, 18%, and 22% for intervals of two hours, within two weeks, and ove...
