深吸气量和用力呼气量在支气管哮喘急性发作期的相关性研究

The correlation between FEV_1 and FIV_1 in patient of asthma

目的研究FEV1和FIV1在支气管哮喘急性发作期的相关性。方法观察支气管哮喘80例在吸入支气管扩张剂前后PEF,FEV1,FVC,FIV1和FIVC的变化。结果支气管哮喘患者PEF,FEV1和FIV1等指标,在吸入支气管扩张剂前后均有明显的差异,且FEV1改善率和FIV1改善率在统计学无差异。结论在评价支气管可逆性方面,FIV1与FEV1具有明显的相关性,两者具有同样的效果。

Objective To study the correlation between the forced inspiratory parameters and forced expiratory parameters in the asthma patients. Methods To make mesurement of the values of PEF, FEV1, FVC, FIV1 and FIVC of the eighty asthma patients before and after inhalation of bronchodilation, and calculate their absolute changes. Results There was significant difference between the values before and after inhalation of the bronchodilation, and there was no difference between the variance of FEV1 and FIVe. Conclusion In asthma patient ,FIV1 and FEV1 have the same effect to evaluate the reversibility of the air way.
