Exercise-induced asthma without respiratory heat loss.
It is well documented that exercise-induced asthma is more pronounced when inspired air is cold and dry rather than warm and humid.' 2 The severity of exercise-induced asthma is closely dependent on loss of respiratory heat, needed to warm and humidify inspired air,3 and it has been suggested that airway cooling is the only stimulus triggering postexercise bronchoconstriction.3-7 We present a c...
متن کاملRespiratory heat/water loss alone does not determine the severity of exercise-induced asthma.
Respiratory heat loss (RHL) or water loss (RWL) have been proposed as possible triggering factors in exercise and hyperventilation-induced asthma (EIA and HIA). It has recently been demonstrated that exercise intensity and climatic factors are both important in determining the severity of EIA. Eight young asthmatics performed both exercise and isocapnic hyperventilation (IHV) manoeuvres under i...
متن کاملIs Exercise-Induced Bronchoconstriction Exercise-Induced Asthma?
The article in this issue of RESPIRATORY CARE by Burnett et al1 reports that 34 of 80 college athletes had exerciseinduced bronchoconstriction (EIB), most in the absence of symptoms. The authors further suggest that these athletes are at risk and that the identification of those with EIB may prevent morbidity and mortality. The implication is that the presence of EIB is evidence for asthma. But...
متن کاملExercise-induced asthma.
A review of exercise-induced asthma is presented which describes work that has been carried out by the authors and by other investigators over recent years. The effect of exericse on lung function in asthmatic and normal subjects is compared. The influence of the type and severity of exercise on the response of the asthmatic is noted and the importance this has for interpretation of results. Th...
متن کامل[Exercise-induced asthma].
All asthmatics have exercise-induced asthma (EIA). In periods where the asthma spontaneously deteriorate, there will be more exercise-induced asthma. About 3/4 of the asthmatics will have a positive exercise test on the first challenge. Exercise is not the best test to obtain the diagnosis of asthma, as other tests, e.g. inhalation of histamine, is more sensitive and specific. The best pretreat...
