The impact of body position on jugular venous flow was studied in 10, and the impact of head position in 33 healthy young volunteers using an ultrasonic Doppler flowmeter. Flow in the right internal jugular vein decreased by 40 +/- 21% with the individuals positioned on their left side. Turning of the head to the contralateral side reduced right internal jugular venous flow by 42 +/- 24% in 18 cases, whereas flow increased by 79 +/- 67% in 15. The respective values for the left internal jugular vein were 35 +/- 26% in 14, and 92 +/- 86% in 18 cases.
使用超声多普勒流量计，对10名健康年轻志愿者研究了体位对颈静脉血流的影响，对33名健康年轻志愿者研究了头部位置对颈静脉血流的影响。当个体左侧卧位时，右侧颈内静脉血流减少40±21%。在18例中，头部转向对侧时右侧颈内静脉血流减少42±24%，而在15例中血流增加79±67%。左侧颈内静脉在14例中的相应值为35±26%，在18例中为92±86%。
