背景：乙酰甲胆碱激发试验(MCT)中导致第一秒用力呼气量(PC20-FEV1)较基线下降20%的乙酰甲胆碱浓度通常不被认为是学龄前儿童的诊断工具，因为PC20-FEV1可能无法实现
Background: The concentration of methacholine that causes a fall of 20% from baseline forced expiratory volume in the first second (PC20-FEV1) in the methacholine challenge test (MCT) is not usually considered a diagnostic tool in preschool children since PC20-FEV1 may not be achievable
