  [Abstract] Objective To study and analyze the clinical application value of pulmonary function test in the identification of bronchial asthma, chronic obstructive pulmonary disease (COPD) and asthma chronic obstructive pulmonary disease overlap syndrome. Methods From January 2015 to March 2017, 90 patients with respiratory disease who were admitted to our hospital were randomly selected according to the type of diseases and divided into three groups. Bronchial asthma patients(n=30) were assigned to observation group A, COPD patients(n=30) were assigned to observation group B, and patients with asthma COPD overlap syndrome(n=30) were assigned to observation group C. The lung function was tested for the three groups of patients, including the determination of diffusion function, pulmonary ventilation and lung capacity measurement. The required relevant data were recorded in detail and were analyzed and compared. Results The results showed that the lung ventilation function index of patients in observation group A was significantly higher than that in observation group B and C, and the lung ventilation function index in observation group B was higher than that in observation group C, the difference was statistically significant(P0.05). The lung volume function index in observation group A was lower than that in observation group B, C, the difference was statistically significant(P0.05). In observation group A, DLCO, Dm predicted value % and DLCO/VA were significantly higher than those in observation group B and C, and the DLCO, Dm predicted value % and DLCO/VA in group C were higher than those in observation group B. The difference was statistically significant(P    [Key words] Pulmonary function measurement; Bronchial asthma; Chronic obstructive pulmonary disease (COPD); Asthma chronic obstructive pulmonary disease overlap syndrome
  支气管哮喘、慢阻肺患者体内均存在多种炎症细胞或炎性介质,为炎症性呼吸系统疾病,患者均伴有气流受限症状,临床上多见患者咳嗽、咳痰或气喘等不良症状,准确诊断难度较大[1]。有研究结果显示支气管哮喘、慢阻肺有并存情况,即哮喘慢阻肺重叠综合征。三种病情多方面情况极为相似,准确鉴别难度很大[2]。按照病症类型将所选患者90例分为三组进行研究,测定患者肺通气功能、肺容量、弥散功能后对所获相关数据分析总结,探讨肺功能测定鉴别支气管哮喘、慢阻肺及哮喘慢阻肺重叠综合征的临床价值,现将报道如下。
  1 资料与方法
  1.1一般资料
  随机选取2015年1月~2017年3月我院收治的呼吸道疾病患者90例,按照病症类型将其分为三组:观察A组30例,患者男女占比为19∶11;年龄46~79岁,平均(62.18±10.42)岁。观察B组30例,患者男女占比为17∶13;年龄43~71岁,平均(60.51±10.03)岁。观察C组30例,患者男女占比为15∶15;年龄45~78岁,平均(61.57±10.49)岁;三组患者一般资料比较,差异无统计学意义(P>0.05),具有可比性。
  1.2 方法
  用Masterscreen PFT肺功能仪对三组患者肺通气功能、肺容量、肺弥散功能进行测定。肺通气功能指标为:VC、FEV1、FVC、FEV1/FVC、PEF、MMEF;肺容量功能指标为:FRC、RV、TLC、RV/TLC;肺弥散功能指标为:DLCO、VA、Dm,DLCO值经Hb校正、计算DLCO/VA[3]。
  1.3观察指标[4]
  观察三组患者VC、FEV1、FVC、FEV1/FVC、PEF、MMEF、FRC、RV、TLC、RV/TLC、DLCO、VA、Dm、DLCO/VA,并将所获相关数据作对比分析。
  1.4 统计学方法
  采用SPSS20.0软件对本文数据进行分析处理,其中计量资料以(x±s)表示,采用t检验或方差分析;计数资料以[n(%)]表示,采用χ2检验,P0.05)。见表1。
  2.2 三组患者肺容量功能测定结果比较
  观察A组患者肺容量功能指标除TLC外均低于观察B、C组(P0.05)。见表2。
  2.3 三组患者弥散功能测定结果比较
  观察A组患者DLCO、Dm预计值%及DLCO/VA高于观察B、C组(P参考文献]
