During the sleep person is in the state of antiorthostasis, this state provokes vascular cerebral abnormalities (night cerebral hypervolemia). The nature of encephalon blood supply is changing in this horizontal state, in the result there is lowering of hydrostatic blood pressure, rise of the encephalon blood supply and more difficult venous outflow. 60 patients with essential hypertension (1-2 phases) at the age of 64.2 +/- 1.8 years which were in the state of slightly raised upper segment of the head and body during night sleep were examined. By the method of the cerebral venous hemocirculation defined. Conclusion. Cerebral arterial blood flow of examined patients has increased by 25-30% during the sleep, the changes of arterial and cerebral venous hemocirculation have attended hypervolemia. Being in the state of upper (by 10-15 degrees) head of the bed decreases blood redistribution and decreases the extension of cerebral blood circulation's acute abnormalities. |
