The scope of application of hyperbaric oxygen chamber is very wide, and it is mainly used for the treatment of anaerobic bacterial infection, CO poisoning, air embolism, decompression sickness, ischemic-hypoxic encephalopathy, cerebral trauma, cerebrovascular disease and so on.
Working Principle
Oxygen is carried by the blood, oxygen into the lungs will immediately dissolve into the blood, the process of dissolution is like putting a spoonful of sugar into the water is quickly dissolved. The amount of oxygen dissolved in the blood of a normal person is related to the environmental pressure, we live in an atmospheric pressure environment, because the oxygen in the air is only 1/5, so the oxygen dissolved in the blood is very little to meet the needs of the human body. Oxygen can easily enter into the red blood cells and transported with the movement of red blood cells, the little oxygen dissolved in the blood is very important. Because the red blood cells carry dozens of times more oxygen than the oxygen dissolved in the blood, a normal person can meet the oxygen intake of the transported oxygen. Such as hyperbaric oxygen experiment: 1956 Dutch scientists experiments. The blood from the arteries on the piglet and then injected into the vein from the saline, and then put into the hyperbaric oxygen chamber and add three atmospheric pressure of oxygen, the piglet in this hyperbaric oxygen chamber live 15 minutes, the blood re-entered into the piglet's body it is still alive or very good, the piglet is relying on the dissolved oxygen and continue to live, scientists will be the experiment named the bloodless life. After many experiments, it was concluded that the oxygen dissolved in the blood of a person in a hyperbaric oxygen chamber increases with the pressure of the chamber. Oxygen dissolved in the blood increased 14 times after inhaling pure oxygen at 2 atmospheres, and 21 times at 3 atmospheres.
Scope of application
Hyperbaric oxygen is suitable for the following diseases: gas, hydrogen sulfide, methane gas and other harmful gas poisoning, cerebral thrombosis, cerebral hemorrhage, traumatic brain injury, neuritis, vasculitis, diabetic gangrene, hard-to-heal ulcers, fetal dysplasia, neonatal asphyxia, acute pneumothrombosis, decompression sickness, altitude sickness, sudden deafness, Meniere's syndrome, vertigo. Compared with ordinary oxygen intake, hyperbaric oxygen is stronger and more effective, and can directly utilize the amount of oxygen to solve the problem of hypoxia, hyperbaric oxygen also has antibacterial and other effects.
Treatment of gas poisoning
Inhaled carbon monoxide and red blood cells, red blood cells combined, combined with the red blood cells crowded out the ability to transport oxygen, people in normal circumstances is to rely on oxygen to survive, and gas poisoning in the body after the replacement of oxygen by carbon monoxide, this time will be lack of oxygen. The brain is the most in need of oxygen, gas poisoning symptoms are neurological manifestations, mild symptoms such as dizziness, headache, nausea, vomiting, lack of energy, serious coma, these are related to the lack of oxygen in the brain. Carbon monoxide and red blood cells have a stronger binding capacity than oxygen, will be put into the gas poisoning patients have fresh air, due to the oxygen content of the atmosphere is only 1/5 of the air, so the excretion of gas poisoning takes 10-20 hours, and will be sent to the hyperbaric oxygen chamber of the gas-poisoned patient after the patient's inhalation of oxygen is far greater than the oxygen content of the air, many very heavy patients in the treatment is not yet over when they woke up, 40
The symptoms of poisoning can be relieved after 50 minutes.
Treatment of cerebral thrombosis
Into the hyperbaric oxygen chamber benefits are: from the surrounding normal brain tissue to the focal area of blood supply. Inverted blood and reverse inverted blood phenomenon: give patients with cerebral thrombosis to eat blood vessel expansion drugs after normal brain tissue cells react sensitively to the drugs, the focal area of the response is not very sensitive, and blood vessels are not dilated, the brain's blood from the normal brain tissue is also expansion of the place of the flow through, but not through the focal area of the phenomenon is called inverted blood. Hyperbaric oxygen therapy has the effect of reversing blood flow.
Side effects
Conventional HBO treatment, will not produce any side effects, if the staff improper operation, do not follow the operating procedures, or not scientific, unauthorized changes in the treatment program, can produce serious consequences. I) Oxygen poisoning: refers to high pressure or atmospheric pressure, inhalation of high concentration of oxygen up to a certain period of time, oxygen on the body to produce functional or organic damage. Oxygen poisoning can be divided into central type, pulmonary type, hemolytic type and eye type. No matter which type of oxygen intoxication occurs, the whole body is victimized at the same time. Clinically, oxygen inhalation under pressure higher than 0.3MPa, prolonging oxygen inhalation time at will during routine treatment, and prolonged inhalation of oxygen with a concentration higher than 50% under atmospheric pressure are the common causes of oxygen poisoning. The mechanism has three aspects: 1, the toxic effect of oxygen on central metabolism; 2, the toxic effect of oxygen on enzymes; 3, the excessive production of free radicals. As soon as oxygen toxicity occurs, stopping oxygen immediately usually relieves the symptoms. Vitamin E, C, K, magnesium ion preparations can prevent oxygen poisoning. (ii) pneumatic pressure injury: common middle ear pneumatic pressure injury, paranasal sinus pneumatic pressure injury and lung pneumatic pressure injury. In addition, decompression in the pneumothorax patient is not timely found and dealt with, can make the thoracic cavity gas over-expansion, lung and heart pressure, mediastinal swing, can lead to sudden death of the patient. (C) Decompression sickness: a high-risk situation in which decompression is too fast and too large, reducing the solubility of gases in the tissues and freeing them to form bubbles in the blood and tissues, resulting in vascular air embolism and tissue compression. Fortunately, this situation mostly occurs in diving operations and is very rare in general HBO treatment. As long as we pay attention to our thoughts and operate in strict accordance with the protocol, this disease is not difficult to prevent.
