System analysis was performed on 16 adult mongrel dogs to determine the origin of the lumbar cerebrospinal fluid pulse wave. The descending thoracic aorta was occluded to evaluate the effects of the spinal arterial pulsations, and the thoracic aorta and inferior vena cava were simultaneously occluded to evaluate the effects of the spinal venous pulsations. It was concluded that, in the first harmonic wave, the components of the lumbar cerebrospinal fluid pulse wave are as follows: spinal arterial pulsations, 39.4%; spinal vascular (arteries and veins) pulsations, 77%; venous pulsations in the spinal canal, 37.6%; and the intracranial pressure pulse wave transmitted through the spinal canal from the intracranial space to the lumbar level, 23%.
对16只成年杂种狗进行系统分析，以确定腰段脑脊液脉搏波的起源。阻断胸降主动脉以评估脊髓动脉搏动的影响，同时阻断胸主动脉和下腔静脉以评估脊髓静脉搏动的影响。得出的结论是，在一次谐波中，腰段脑脊液脉搏波的组成部分如下：脊髓动脉搏动，39.4%；脊髓血管（动脉和静脉）搏动，77%；椎管内静脉搏动，37.6%；以及从颅内空间通过椎管传递至腰段水平的颅内压脉搏波，23%。
