1.What is hyperbaric oxygen? Breathing pure oxygen at more than one atmosphere is called hyperbaric oxygen therapy, and it can have special effects on many diseases. 2.What is the difference between normobaric oxygen and hyperbaric oxygen? Normal oxygen is breathed in an atmospheric pressure environment, and the inhalation is not pure oxygen, the concentration and pressure of oxygen is small without the effect of hyperbaric oxygen. Hyperbaric oxygen has changed qualitatively compared to atmospheric oxygen and has become something else, so the two should not be confused. Hyperbaric oxygen is not just a small increase in the amount of oxygen compared to normobaric oxygen, many of the therapeutic effects of hyperbaric oxygen are unique and cannot be replaced by normobaric oxygen, and for some special diseases, such as gas embolism, gas gangrene, decompression sickness, carbon monoxide poisoning, etc., the therapeutic effects of hyperbaric oxygen are impossible to achieve with normobaric oxygen and drug therapy. 3.Is hyperbaric oxygen therapy a general treatment? Hyperbaric oxygen is a common treatment, there are more than 2,000 hospitals nationwide have hyperbaric oxygen chambers, and hospitals above the county level can generally do hyperbaric oxygen therapy. 4.Will hyperbaric oxygen therapy cause any uncomfortable feeling? Hyperbaric oxygen therapy can be uncomfortable, like landing in an airplane, with tinnitus and buzzing sound. Patients can do some nose pinching, puffing action or swallowing action to reduce the pressure on the eardrum will be relieved. 5.What diseases is hyperbaric oxygen therapy effective for? Acute carbon monoxide poisoning and delayed encephalopathy; other toxic gas poisoning (hydrogen sulfide, phosgene, carbon dioxide, ammonia, chlorine, methane, methane, liquefied petroleum gas, etc.); poisoning by hydride, nitrite, benzene, aniline, gasoline, etc., acute drug poisoning; decompression sickness; acute gas embolism; gas gangrene, tetanus and other anaerobic or mixed aerobic and anaerobic bacterial infections; cranio-cerebral, spinal cord and peripheral nerve injury; recovery of brain function after cardiopulmonary resuscitation (cerebral resuscitation); asphyxia (smoke, drowning, neck constriction, electric shock, anesthesia accident, etc.); post-arterial anastomosis, poor blood supply to the severed end; poor growth of the severed limb or flap after amputation or implantation; sudden deafness, chronic periodontal disease; thrombo-occlusive vasculitis, occlusive atherosclerosis, diabetic foot; intracerebral infection (meningitis, encephalitis, brain abscess); facial neuritis, migraine, epilepsy secondary to traumatic brain injury; neurological reaction after traumatic brain injury; ischemic cerebrovascular disease; delayed healing or non-healing of fracture; radiological osteonecrosis; chronic osteomyelitis; extrusion syndrome; interfascial compartment syndrome; various traumas, burns, frostbite, electric shock; chronic hard-to-heal ulcers, hard-to-heal wounds, decubitus ulcers. 6.How many courses of hyperbaric oxygen treatment for sudden deafness are needed? After 1-2 courses (10-20 times), it can be effective, and more than 80% of patients can recover. 7.Is hyperbaric oxygen effective in treating traumatic brain injury? The effect of hyperbaric oxygen on acute craniocerebral trauma is very significant. It has obvious effect on the recovery of consciousness, improvement of memory and recovery of neurological function. 8.How much is the treatment course of hyperbaric oxygen therapy in general? A course of hyperbaric oxygen therapy is ten days, once a day, and it takes 2-3 courses for general disease treatment.
