The hypoxemia-hypercapnia test with closed-space breathing has been performed in 71 children aged 9-15. The examinees comprised three groups: healthy controls (n = 12), patients with latent cerebral angiodystonia (n = 9), patients with clinical cerebral angiodystonia (n = 50). The patients could hardly tolerate closed-space breathing. They complained of head aches, dizziness, suffered from vegetative stigmas, neurological deficiency. In subclinical and apparent disease vegetative dysadaptation predominated in the parasympathetic and dysregulatory forms. The load-provoked increase in the linear blood flow rate and a decrease in the resistance index appeared more pronounced in the controls. This evidences reduced adaptive potential of brain autoregulation in patients with cerebral angiodystonia.
对71名9至15岁的儿童进行了密闭空间呼吸的低氧血症-高碳酸血症试验。受试者分为三组：健康对照组（n = 12）、潜在脑血管张力障碍患者（n = 9）、临床脑血管张力障碍患者（n = 50）。患者很难耐受密闭空间呼吸。他们抱怨头痛、头晕，患有植物神经症状、神经功能缺陷。在亚临床和明显疾病中，植物神经适应不良以副交感神经和调节障碍形式为主。负荷诱发的线性血流速度增加和阻力指数降低在对照组中更为明显。这证明脑血管张力障碍患者脑自动调节的适应潜力降低。
