运动诱导的支气管收缩(EIB)在哮喘儿童中有特殊重要性,运动试验可用来监测哮喘控制情况。但由于会给医疗单位造成巨大负担,往往不能广泛应用。丹麦研究人员测定了111例轻-中度哮喘、准备接受运动试验的学龄儿童的呼气中一氧化氮浓度(FeNO)。结果显示,有明显EIB者比运动试验阴性者,基础时1秒用力呼气量(FEV1)明显降低。当哮喘儿童FeNO浓度 <20／ppb时,使用β2激动剂;或FeNO<12／ppb 时,使用目前的吸入激素治疗,90％以上的患者不会产
Exercise-induced bronchoconstriction (EIB) is of special importance in asthmatic children and exercise testing can be used to monitor asthma control. However, it can not be widely applied because of the huge burden on medical units. Danish researchers measured the levels of exhaled nitric oxide (FeNO) in 111 mild-moderate asthmatic children who were ready to undergo exercise tests. The results showed that significant EIB than exercise test negative, based on 1 second forced expiratory volume (FEV1) was significantly lower. When asthma children have FeNO concentrations <20 / ppb with beta 2 agonists or FeNO <12 / ppb, with current inhaled steroids, more than 90% of patients do not produce
