为研究当下鼻甲血容量发生变化时,鼻甲粘膜血流是否发生同步改变,作者使用激光多普勒流量法测量鼻粘膜血流,前鼻测压法间接测量下甲血容量。选15名健康受试者(男6女9,年龄24～54岁,平均34.6岁),每位受试者均无明显鼻中隔偏曲及鼻窦炎症。每次测量前两仪器均先开机1小时,校准,每位受检者端坐休息1刻钟,整个过程患者均处于正坐 In order to study whether changes of turbinate blood volume occur at the moment, whether the nasal mucosal blood flow changes synchronously, the authors measured the blood flow of the nasal mucosa by laser Doppler flowmetry and the anterior indirect nasal pressure measurement. Fifteen healthy subjects (6 males and 9 females, aged 24-54 years, average 34.6 years) were enrolled in this study. No deviation of nasal septum and sinusitis were observed in each subject. Before each measurement, the two instruments were turned on for 1 hour and then calibrated. Each subject took a rest for 1 minute and the patient was sitting
