Hyperbaric oxygenotherapy is a treatment method in which patients inhale pure oxygen under increased pressure in a special chamber. This therapy stimulates tissue regeneration, reduces inflammation, and accelerates wound healing. It is used primarily for non-healing ulcers, diabetic foot, burns, hearing disorders, and carbon monoxide poisoning. Before starting treatment, approval from a specialized physician and confirmation of the patient's fitness for the procedure from a general practitioner is required. The procedure lasts approximately 120 minutes and patients typically undergo it once daily, with the number of sessions ranging from 10 to 80 per year depending on diagnosis severity. The method is not suitable for patients with acute respiratory infections, severe heart or lung diseases, uncontrolled hypertension, and certain types of implants. Health insurance companies cover the entire treatment for patients with indicated diagnoses.
