研究者以每个参与者肱动脉流量介导的舒张值作为基线，并在CPAP治疗8周后进行了同样的测定。
The researchers measured brachial artery flow-mediated dilation in each participant at baseline and 8 weeks after CPAP therapy.
用彩色多普勒超声血流仪检测血管中央的时间-流速，以评估血流量的基线。

首先描计基线5分钟使其适应，观测其特点，此时的监测曲线反映了颈椎中立位安静状态下脑组织血红蛋白含量即脑血流量情况。
First draw the basic curve for 5 minutes, observe its characteristics. At that time the monitoring curve reflects the brain oxygen situation and the brain blood during a tranquil state.
