Hyperbaric oxygen chambers, also known as hyperbaric oxygen therapy chambers or simply HBO (Hyperbaric Oxygen), are medical devices that provide pressure higher than normal atmospheric pressure and deliver pure oxygen for human inhalation.
Hyperbaric oxygen therapy is a non-invasive treatment method in which patients inhale a large amount of pure oxygen to increase the concentration and partial pressure of oxygen in the blood, allowing more oxygen to enter body tissues. This can accelerate wound healing, enhance white blood cell activity, boost the body's antibacterial ability, and improve or restore some dysfunctions caused by hypoxia. Hyperbaric oxygen therapy plays an important role in the treatment of many diseases and conditions, such as alleviating radiation injuries, treating some refractory wounds, promoting the healing of foot ulcers in diabetic patients, addressing decompression sickness in divers, and treating hypoxic brain injuries.
The specific applications of hyperbaric oxygen chambers mainly include the following areas:
1. Rapidly correcting the body's hypoxic state: Hyperbaric oxygen can increase blood oxygen content, raise blood oxygen partial pressure, and increase physically dissolved oxygen in plasma. It can be used to treat cardiovascular diseases, cerebrovascular accidents, acute brain dysfunction after cardiopulmonary resuscitation, carbon monoxide poisoning, and various other toxic poisonings.
2. Effectively improving microcirculation: By enhancing the diffusion capacity of oxygen in the blood, it increases the effective diffusion radius of oxygen, as well as oxygen content and storage in tissues. This can treat diseases accompanied by microcirculation disorders, such as burns, frostbite, crush injuries, shock, skin grafts, bone grafts, and limb replantation.
Prevention and treatment of various types of edema: Hyperbaric oxygen has a vasoconstrictive effect, which can reduce vascular permeability and decrease vascular and tissue exudation, improving different types of edema. For example, it can treat cerebral edema and reduce intracranial pressure by 30-40%, address limb swelling, wound exudation, and reduce fluid loss in patients with extensive burns.
