目的探讨简易肺功能检测在支气管哮喘(哮喘)诊断和病情评估中的意义。方法哮喘患者64例分为哮喘完全控制(A组,10例)、部分控制(B组,28例)和未控制(C组,26例)三组,以36例健康人(D组)作为对照,分别行简易肺功能检测,分析哮喘患者肺功能的特点。结果A、B、C组第1秒用力呼气量占预计值百分比(FEV_1%pred)、第1秒用力呼气量占用力肺活量百分比(FEV_1/FVC)及呼气峰值流速(PEF)均低于D组(P<0.05),且随哮喘严重程度的增加而逐渐降低(P<0.05)。结论简易肺功能测定有助于哮喘患者的诊断和病情评估。
Objective To explore the significance of simple pulmonary function test in the diagnosis and assessment of asthma. Methods Sixty-four patients with asthma were divided into three groups: control group A (n = 10), partial control group B (n = 28) and uncontrolled group C Control, respectively, simple pulmonary function test, analysis of lung function in patients with asthma characteristics. Results FEV 1% pred, FEV 1 / FVC and PEF were lower in groups A, B and C than those in group B D group (P <0.05), and decreased with the severity of asthma (P <0.05). Conclusions The simple pulmonary function test is helpful for the diagnosis and assessment of asthma.
