众所周知,有严重气道阻塞病变(如慢性支气管炎和肺气肿)的病人对运动的耐受性降低,但此时气道反应性并未增加。然而哮喘并非如此,一旦体力负荷增加时,不可避免地会导致哮喘急性加剧,因此哮喘病人对运动的反应性是独特的。本文就哮喘病人运动试验的生理、病理生理及其诊断价值诸方面作一探讨。【运动时的循环、通气和代谢反应】 It is well-known that patients with severe obstructive airway disease (such as chronic bronchitis and emphysema) have reduced exercise tolerance, but their airway reactivity has not increased at this time. However, asthma is not the case, once the increase in physical load, it will inevitably lead to an acute exacerbation of asthma, so the responsiveness of patients with asthma is unique. This article discusses the physiological, pathophysiological and diagnostic value of asthma patients exercise test. Circulation, Ventilation and Metabolic Response during Exercise
