监测38名支气管哮喘患者及38名正常对照者的呼气流速峰值(PEFR)的昼夜变化,发现哮喘病人PEFR昼夜变化比值A的均值为29.0%,明显高于正常组(8.8%),可作为诊断哮喘的重要依据。哮喘病人以清晨下降型(占79.3%)为其昼夜变化的特征性类型,对这方面的深入研究将有助于哮喘病的诊治。
The diurnal changes of peak expiratory flow (PEFR) in 38 asthma patients and 38 normal controls were observed. The mean value of diurnal change of PEFR in asthma patients was 29.0%, which was significantly higher than that of the normal group (8.8%), An important basis for diagnosis of asthma. Asthmatic patients with early morning type (79.3%) as the diurnal variation of the characteristic types, in-depth study in this area will contribute to the diagnosis and treatment of asthma.
