The brain is inside the cranium and consists of the mind, diencephalon, brain stem and cerebellum. The brain is globular, and the face of the cerebral semicircle is called the cerebral cortex. The brain is composed of innumerous whim-whams cells and brain cells, and brain cells are veritably sensitive to hypoxia. In cerebral atherosclerosis, the blood inflow of vegetative cells in small highways is reduced, and the function of brain cells is also reduced. When cerebral thrombosis occurs in cerebral highways; cerebral embolism, cerebral aneurysm rupture or hemorrhage or excrescence contraction, brain cells can suffer degeneration and necrosis.

Cerebrovascular complaint refers to the blood force disease of the brain tissue caused by the disease of the blood vessel itself or the disorder of the blood rotation of the whole body.

Cerebrovascular complaint is one of the common clinical conditions. According to applicable statistics, the prevalence rate is 150-200 people per people. The death rate of cerebrovascular conditions reached101.31 to 117 52 people per, counting for 15 to 20 of the total deaths from colorful conditions. The prevalence of cerebrovascular conditions is nearly related to age. The aged the age, the advanced the prevalence. Ultramodern drug lists cerebrovascular conditions, nasty excrescences, and cardiovascular conditions as the top three conditions with the loftiest mortality in humans’ moment.

The average weight of the brain is 1500 grams, which is 2 to 3 % of the total body weight, but its oxygen consumption accounts for 20% of the total body oxygen input. The metabolism of the brain requires 72 liters of oxygen and 150 grams of glucose every 24 hours. Each time the heart contracts 70 ml of blood, of which 10 to 15 ml is supplied to the brain. Also, the energy reserve and anaerobic metabolism capacity of brain towel is extremely small, generally only a veritably small quantum (about 2 grams) of glucose and glycogen are stored, and energy metabolism is nearly entirely dependent on the nonstop transport of glucose and oxygen by the bloodstream. Under normal body temperature, if hypoxia, the physiological function of the brain can only be maintained for 4-6 twinkles, the midbrain can be maintained for 5-10 twinkles, the cerebellum can be maintained for 10-15 twinkles, and the medulla oblongata can be maintained for 20-30 twinkles. In other words, if the mortal body is hypoxic, the brain tissue, especially the cortex of the brain, will be the first to bear the mass. When the force of glucose and oxygen is reduced to a critical position, the function of brain cells can only be maintained for a many twinkles. Thus, when a case suffers from cerebrovascular complaint, it'll affect the respiratory center and beget hypoxia. Hypoxia can increase the permeability of original brain capillaries, traffic and edema of the brain towel, and brain edema, which in turn makes the hypoxia miracle more serious. Severe cerebral hypoxia, the astrocytes around the capillaries snappily swell, compressing the capillaries, making the lumen narrow or indeed misshaped, and the capillary endothelial cells also swell, forming rash-suchlike projections of varying sizes. Narrow or block the lumen, block blood inflow, beget ischemia or blood counterpoise, and aggravate cerebral hypoxia and edema.

Cerebrovascular disease is a constantly- being complaint in the senior, and the condition is more critical. In the event of an unforeseen attack, if there's no immediate oxygen replenishment measures, indeed if saved, further than1/3 will be left with endless disability, and some may fall again. Thus, oxygen health care and exigency oxygen delivery are veritably important for the forestallment and treatment of cerebrovascular conditions. We can supply you with various medical oxygen concentrators to save your life in time.

Common conditions of the cerebrovascular system include cerebral ischemia, cerebral thrombosis and cerebral embolism, and cerebral vertigo. In addition, numerous neurological conditions don't directly beget hypoxia in the brain, but the final result is hypoxia in brain tissue, similar as spinal cord injury, cranial whim-whams and supplemental neuropathy (similar as trigeminal neuralgia, facial whim-whams paralysis, polyneuritis, gravis Asthenia) and so on.
