Air pressurization maximum working pressure is not greater than 0.3MPa, oxygen pressurization maximum working pressure is not greater than 0.2MPa.
High-pressure oxygen chamber according to the pressurized medium is divided into two kinds of air pressurized chamber and pure oxygen pressurized chamber. The use of hyperbaric oxygen chamber has a wide range of clinical mainly used for anaerobic infection, CO poisoning, gas embolism, decompression sickness, ischemic hypoxic encephalopathy, brain trauma, cerebrovascular disease and other treatment.
Principle of hyperbaric oxygen:
One, the role of pressure: the body's bubbles in the pressure rise, its volume will be reduced. Reduce the scope of infarction; facilitate the dissolution of air bubbles in the blood.
Two, pressure effect vasoconstriction effect: hyperbaric oxygen has alpha-adrenergic-like effect to make blood vessels contract, reduce local blood volume, conducive to cerebral edema, burns or crush injuries after edema reduction. It should be noted that although the local blood supply is reduced, but the amount of oxygen brought into the tissue through the blood is increased.
Three, antibacterial effect, it is not only anti-anaerobic bacteria, but also anti-aerobic bacteria.
