Abstract

Synchronous electro- and rheoencephalography were used to study tolerance to moderate hypoxic hypoxia for 30 min at an altitude of 5000 m without additional oxygen supply. As test subject, men with autonomic-vascular dystonia (29-39 years old), 15 men over 40 (41-56 years old), and 16 essentially healthy controls (23-36 years old) were used. The aged volunteers (41-56 years old) did not differ from the controls with respect to their tolerance to hypoxic hypoxia. The men with early symptoms of hypertonic-type dystonia also showed high tolerance to hypoxic hypoxia. The subjects with hypotonic-type dystonia displayed lower tolerance.

摘要

采用同步脑电图和脑血流图研究了在海拔5000米且无额外供氧情况下,30分钟中度低氧性缺氧的耐受性。作为测试对象,使用了患有自主神经血管性肌张力障碍的男性(29 - 39岁)、15名40岁以上男性(41 - 56岁)以及16名基本健康的对照者(23 - 36岁)。老年志愿者(41 - 56岁)在低氧性缺氧耐受性方面与对照组没有差异。患有高张型肌张力障碍早期症状的男性对低氧性缺氧也表现出高耐受性。患有低张型肌张力障碍的受试者耐受性较低。
