【摘要】：目的：通过对呼气峰速仪及肺功能仪所测出的PEF％Pred进行相关性及差异性统计学分析，探讨呼气峰速仪在支气管哮喘病患诊疗中的临床应用价值。方法：选取64名哮喘病患，分别用呼气峰速仪及肺功能仪对其进行PEF测定，计算PEF％Pred；用肺功能测出FEVl％Pred，对FEVl％Pred＞70%的51名哮喘病患进行激发试验，对FEVl％Pred＜70%的13名哮喘病患进行扩张试验，同时再用呼气峰速仪及肺功能仪对64名哮喘患者进行PEF测定，计算PEF％Pred；对呼气峰速仪及肺功能仪分别测出的前PEF％Pred、后PEF％Pred进行相关性及差异性分析。结果：呼气峰速仪及肺功能仪分别测出的前PEF％Pred明显相关（r=0.884，P＜0.01）,经配对t检验差异无统计学意义（P＞0.05）；激发试验后二者PEF％Pred明显相关（r=0.666，P＜0.01），经配对t检验差异无统计学意义（P＞0.05）；扩张试验后二者PEF％Pred明显相关（r=0.863，P＜0.01），经配对t检验差异无统计学意义（P＞0.05）；结论：呼气峰速仪体积小，操作简单，价格低廉，与肺功能仪相比，体现了优越性，可应用于支气管哮喘患者，，根据PEF％Pred评估气道阻塞程度，对哮喘患者诊疗起到重要指导作用。
[Abstract]:Objective: To explore the clinical value of the expiratory peak velocity in the diagnosis and treatment of bronchial asthma by analyzing the correlation and difference of PEF%Pred detected by the peak expiratory velocity meter and the pulmonary function instrument.
Methods: 64 patients with asthma, expiratory and pulmonary function instrument for PEF measurement, calculation of PEF%Pred; pulmonary function to detect FEVl%Pred, FEVl%Pred > 70% 51 asthmatic patients were provocation test, FEVl%Pred < 70% to 13 asthmatic patients expansion test, at the same time and then expiratory flow rate instrument and pulmonary function instrument PEF measurement and calculation of PEF%Pred of 64 patients with asthma were measured; the peak expiratory flow meter and pulmonary function before PEF%Pred, analyse the correlations and differences after PEF%Pred.
Results: a significant correlation of peak expiratory flow meter and pulmonary function were measured before PEF%Pred (r=0.884, P < 0.01), paired t test showed no significant difference (P > 0.05); after the provocation test two obviously related to PEF%Pred (r=0.666, P < 0.01), paired t test showed no significant difference (P > 0.05); expansion test after two PEF%Pred significantly correlated (r=0.863, P < 0.01), paired t test showed no significant difference (P > 0.05);
Conclusion: the expiratory peak velocimeter is small, simple and inexpensive, which shows superiority compared with pulmonary function instrument. It can be applied to bronchial asthma patients. According to PEF%Pred, evaluating airway obstruction degree plays an important guiding role in diagnosis and treatment of patients with asthma.
