To assess the autonomic control of the microcirculation in human skin and nasal mucosa, the spontaneous fluctuations of a laser Doppler signal recorded on forearm skin and nasal mucosa were compared with heart rate fluctuations and the respiratory signal in 11 healthy subjects by means of spectral analysis. Possible direct mechanical-thermal effects of airflow on the nasal mucosa were evaluated by comparing recordings obtained when the subjects were breathing through either the nose or the mouth. Comparison of the spectral analysis of the signal obtained for skin and nasal mucosa blood flow allowed us to define the characteristics of the autonomic tone of the microcirculation in these two areas. The skin is mainly influenced by sympathetic activity, and the nasal blood flow is regulated by both sympathetic and parasympathetic activity.
为评估人体皮肤和鼻黏膜微循环的自主控制，通过频谱分析比较了11名健康受试者前臂皮肤和鼻黏膜上记录的激光多普勒信号的自发波动与心率波动及呼吸信号。通过比较受试者经鼻或经口呼吸时获得的记录，评估了气流对鼻黏膜可能的直接机械热效应。对皮肤和鼻黏膜血流信号的频谱分析进行比较，使我们能够确定这两个区域微循环自主神经张力的特征。皮肤主要受交感神经活动影响，而鼻血流则受交感神经和副交感神经活动共同调节。
