Working principle of hyperbaric oxygen chamber

Hyperbaric oxygen therapy was carried out in China in the 1960s, and most hospitals used small and medium-sized oxygen chambers. A few hospitals have established large oxygen chambers, which consist of three chambers and seven doors, including operation chamber, treatment chamber and transition chamber, and can accommodate and treat dozens of people at the same time. Medium-sized cabins are mostly one cabin, two rooms and four doors, which can accommodate several people for treatment or first aid at the same time. The cabin, also known as the single oxygen cabin, can only accommodate 1 person for treatment. The hyperbaric oxygen chamber is sealed and pressure-resistant. By inputting hyperbaric oxygen or high-pressure air into the cabin, a high-pressure environment is formed in the cabin. Patients receive oxygen therapy in the cabin, which can provide effective and sufficient oxygen for the hypoxic body, increase the oxygen reserve in the tissue, inhibit the growth of bacteria and enhance the curative effect of radiotherapy and chemotherapy for malignant tumors. Hyperbaric oxygen therapy must go through three stages: pressurization, stable oxygen inhalation and decompression.

Because oxygen is flammable, patients need to change cotton coats and slippers when they enter the cabin for treatment. It is forbidden to bring matches, lighters, cigarettes, watches, pens and other items into the cabin. The staff can talk with the patient and observe the reaction through the window (hole). Hyperbaric oxygen can treat carbon monoxide and harmful gas poisoning, acute decompression sickness, gas gangrene, brain trauma, pulmonary edema, cerebral ischemia, severe neurasthenia, migraine, drug poisoning and other diseases 100, and can also provide health care for the elderly and improve heart and brain functions.

Hyperbaric oxygen medicine is a new discipline with a history of only over one hundred years, which developed late in China and began in the 1960s. Since the reform and opening up, China has made great progress in the number of oxygen chambers, professional team, scientific research and clinical application, and now it has become a complete discipline, which is increasingly welcomed and highly valued by the medical profession and the broad masses of the people.

Hyperbaric oxygen therapy covers all clinical disciplines, including internal medicine, surgery, obstetrics and gynecology, pediatrics, neurology, neurosurgery, facial features, orthopedics, occupational diseases, burns, trauma, diving, geriatric diseases and sports medicine. In addition, hyperbaric oxygen medicine also involves high-pressure vessels, oxygen supply equipment, air conditioning, lighting, communication, monitoring, surveillance and other engineering and technical disciplines, as well as important majors such as safety and fire fighting. Because hyperbaric oxygen medicine involves a variety of professional disciplines, medical personnel engaged in this major should have rich theoretical knowledge and various medical professional knowledge.

With the rapid development of hyperbaric oxygen in China, a large number of medical, nursing and technical personnel engaged in this profession urgently need to master the knowledge of hyperbaric oxygen medicine in order to carry out their work better. People who have been engaged in hyperbaric oxygen for many years need to know the development of hyperbaric oxygen medicine at home and abroad in order to improve their scientific research, teaching and medical ability and catch up with the advanced level in the world. The majority of medical staff, teachers and students in medical colleges, and engineers and technicians who design and manufacture hyperbaric oxygen chambers need to know more about hyperbaric oxygen medicine. In particular, most hyperbaric oxygen chambers in China are built in primary hospitals and factories and mines, such as prefectures and counties. The equipment and infrastructure of these hospitals are relatively weak, and local hyperbaric oxygen medical staff urgently need to improve their professional level and have higher working ability as soon as possible.

With the rapid development of the Internet, it is more convenient and faster to popularize and exchange hyperbaric oxygen knowledge on the Internet. Here we explain the knowledge of hyperbaric oxygen in detail through five parts: basic part, clinical part, academic monograph, case introduction and relationship with other disciplines.

Basic part: Explain the basic knowledge of hyperbaric oxygen by expounding the brief history of hyperbaric oxygen medicine, the basic concepts of gas physics, the process of air and oxygen in the body, the laws of saturation, desaturation and supersaturation of nitrogen in the body, the physiological functions of hyperbaric oxygen, its side effects, indications, emergencies and contraindications.

Clinical part: through a large number of clinical symptoms, the clinical function of hyperbaric oxygen therapy is explained from the aspects of characteristics, etiology, clinical manifestations, diagnostic criteria, routine treatment and hyperbaric oxygen therapy. Classification of main diseases: brain resuscitation, shock, pulmonary edema, brain edema, occupational diseases, carbon monoxide poisoning and delayed encephalopathy, nervous system diseases, circulatory system diseases, respiratory system diseases, digestive system diseases, other system diseases in internal medicine, surgical diseases, gynecological diseases, pediatric diseases, ophthalmic diseases, otolaryngology diseases, stomatology diseases, dermatology diseases, hyperbaric oxygen and malignant tumors, and the application of hyperbaric oxygen in geriatric diseases and sports medicine.
