A simple spirometer was tested in an outpatient family practice to determine whether its use increased detection of chronic obstructive airway disease (COAD) in patients at risk, more accurately identified patients with reversible bronchospasm, and helped to make the most of their bronchodilator therapy. Three (17 percent) of 18 patients at risk, previously unlabeled, were found to have COAD. Of 28 patients with a previous COAD diagnosis, 5 (18 percent) had the diagnosis deleted, and 5 who had previously been classified as "reversible" were reclassified as having "irreversible" bronchospasm (P less than .025). Of 46 patients studied, bronchodilator therapy was changed in 18 (39 percent); 12 of these improved symptomatically according to a subjective score (P less than .02). A few patients demonstrated a significant improvement in 1-second forced expiratory volume.
在一家门诊家庭诊所对一种简易肺活量计进行了测试，以确定其使用是否能增加对有风险患者慢性阻塞性气道疾病（COAD）的检测，更准确地识别出有可逆性支气管痉挛的患者，并有助于充分利用支气管扩张剂治疗。18名有风险的患者中，有3名（17%）之前未被诊断出患有COAD，此次被发现患有该疾病。在之前被诊断为COAD的28名患者中，有5名（18%）的诊断被撤销，5名之前被归类为“可逆性”的患者被重新归类为患有“不可逆性”支气管痉挛（P小于0.025）。在接受研究的46名患者中，18名（39%）的支气管扩张剂治疗方案发生了改变；根据主观评分，其中12名患者的症状有所改善（P小于0.02）。少数患者的1秒用力呼气量有显著改善。
