Hyperbaric Oxygen Therapy

What Hyperbaric Oxygen Therapy does

HBO2 – Zentrum für Hyperbarmedizin GmbH is a privately held German medical services provider operating hyperbaric oxygen therapy (HBO) centers, headquartered at Habsburgerstraße 116 in Freiburg im Breisgau within the St. Josefskrankenhaus complex. The company, originally established in 2001 as Druckkammerzentrum Freiburg GmbH and led by Managing Director Bernhard Sick, operates three ISO 9001:2015-certified treatment centers across southwestern Germany (Freiburg, Karlsruhe, and Heidelberg), employing 11-50 staff including specialized physicians such as Dr. Claudia Haizmann (Leitende Ärztin Freiburg), Dr. Daniela Oest (Leitende Ärztin Karlsruhe), and Kerstin Schulz (diving and hyperbaric medicine).

The core technology is hyperbaric oxygen therapy delivered in modern multi-place pressure chambers (Mehrplatz-Druckkammer), in which patients breathe pure medical oxygen under increased pressure, increasing the oxygen dissolved in blood up to 20-fold. This enables oxygen delivery to poorly perfused tissues for conditions including chronic non-healing wounds (notably diabetic foot syndrome and radiation late effects), acute hearing disorders (sudden hearing loss, tinnitus, acoustic trauma), bone diseases (aseptic bone necroses, bone marrow edema, Morbus Ahlbäck), Post-COVID/Long-COVID/ME-CFS, emergency diving accidents, carbon monoxide intoxication, and dental indications. The Freiburg site additionally operates the HBO2-Tagesklinik, an interdisciplinary day clinic bundling HBO with wound management, psychotherapy, dietary counseling, and exercise therapy. The company cites clinical evidence from over 3,500 case descriptions and scientific publications.

HBO2 generates revenue primarily through per-treatment-course HBO sessions priced approximately €2,300-3,500 for hearing disorders (typically 10-15 sessions per course, with broader ranges of 10-40 sessions), supplemented by a smaller day-clinic service line and emergency treatments for diving accidents and CO intoxication. Reimbursement is mixed: HBO for diabetic foot syndrome (Wagner Stage II+) has been covered by German statutory health insurance since January 2018 following a G-BA decision, while most other indications (hearing disorders, bone diseases, Post-COVID) remain largely self-pay, with HBO2 assisting patients with private insurance cost-coverage applications. The go-to-market is a hybrid patient-and-physician referral model, with direct intake supplemented by a referring-physician network (HNO, orthopedists, dermatologists, surgeons) and demand-generation through medical symposiums, free patient information evenings, published Behandlungspfade, and the company website.
