峰流速仪在支气管哮喘急性发作患者治疗前后监测的价值

Value of peak flow meter monitoring in patients with acute attack of bronchial asthma before and after treatment

目的:探讨峰流速仪在支气管哮喘急性发作患者治疗前后监测的价值。方法:收治急性发作期哮喘患者50例,采用常规治疗,比较治疗前后最大呼气峰流速(PEF)及肺功能指标1 s用力呼气容积(FEV1)。结果:支气管哮喘患者治疗前后PEF及FEV1比较,差异有统计学意义(P<0.05);PEF与FEV1呈正相关性(P<0.05)。结论:通过测定PEF可以较好地反映急性期哮喘患者病情控制情况,对指导治疗有较大意义。

Objective:To explore the value of peak flow meter monitoring in patients with acute attack of bronchial asthma before and after treatment.Methods:50patients with acute attack of bronchial asthma were selected.They were treated with conventional treatment.We compared maximum expiratory peak flow(PEF)and lung function index FEV1before and after treatment.Results:There were significant differences between PEF and FEV1in patients with acute attack of bronchial asthma before and after treatment(P<0.05).There was a positive correlation between EF and FEV1(P<0.05).Conclusion:Measuring PEF can better reflect the condition control of asthma patients in the acute stage,and it was of great significance for guiding treatment.
