Skin surface blood flow at the fingertips was measured in a 21-year-old woman during sleep using laser Doppler flowmetry. Skin blood flow responses (SBFR) are transient reductions in skin blood flow of about 25s in duration. In our subject, SBFR showed a delay time of 8-9s from the onset of skin potential responses (SPR) and appeared more consistently than SPR. The frequency of SBFR decreased during non-rapid eye movement sleep, especially when the sleep stage became deep. These findings indicate the validity of SBFR as a discrete index of autonomic function during sleep.
使用激光多普勒血流仪对一名21岁女性睡眠期间的指尖皮肤表面血流进行了测量。皮肤血流反应（SBFR）是持续约25秒的皮肤血流短暂减少。在我们的研究对象中，SBFR从皮肤电位反应（SPR）开始出现延迟8 - 9秒，并且比SPR更稳定地出现。在非快速眼动睡眠期间，尤其是睡眠阶段加深时，SBFR的频率降低。这些发现表明SBFR作为睡眠期间自主神经功能离散指标的有效性。
