运动性哮喘(EIA)是进行一定运动量之后出现支气管痉挛而引起的哮喘发作或气道阻力增高。某些哮喘患者,当他们进行剧烈活动或在一定运动量进行锻炼时,常可发生气促、胸闷、呼吸不畅、咳嗽甚至哮喘发作,这些现象特别在寒冷季节运动后更易发生;但对EIA发生、发展及其防治,是近几年才逐渐加深认识.在病理生理上,鉴于EIA主要是运动诱发支气管痉挛(Exercise-Induced Bronchospasm,EIB),因此认为EIA可称为EIB.本文仅就运动诱发EIA诊断的标准及致冷诱发EIA进行观察与讨论. 材料、方法与结果①方法及仪器:测试肺功能仪用日本产SA-500型自动肺量计,自行打印出第一秒用力呼气量(FEV_1)的
Exercise-induced asthma (EIA) is an asthma attack or increased airway resistance caused by bronchospasm after a certain amount of exercise. Some people with asthma often develop shortness of breath, chest tightness, poor breathing, cough, and even asthma attacks when they exercise intensely or exercise for a certain amount of exercise. These phenomena are more likely to occur after exercise in the cold season; however, EIA occurs , Development and its prevention and control is only gradually deepening understanding in recent years.In the pathophysiology, in view of EIA is mainly exercise-induced bronchospasm (Exercise-Induced Bronchospasm, EIB), so that EIA can be called EIB.This article only on exercise-induced EIA diagnostic criteria and refrigeration induced EIA were observed and discussed.Materials, Methods and Results ① Methods and Instruments: Test pulmonary function instrument Japan SA-500 automatic spirometer, to print the first second forced expiratory volume (FEV_1)
