Hyperbaric oxygen therapy (HBO) is a treatment procedure, which includes inhalation of 100% oxygen for a certain duration at a pressure greater than atmospheric. The treatment is carried out in recompression chamber, mono-place (one person) or multi-place (multiple patients at the same time). It is considered as an effective method of treatment, while it remains a useful option in the management of a variety of clinical conditions, both acute and chronic diseases at the same time. The application of HBO treatment aims to increase the cells' oxygen availability, improve tissue resistance, decrease infection and enhance wound healing involved in a number of diseases and injuries. Pathophysiologically, HBO shows a remarkable anti-inflammatory effect and strengthens the immune system against microorganisms, while it promotes wound healing and especially neo-angiogenesis. There are complications/contraindications, such as barotrauma and oxygen toxicity, which are treated appropriately by specialized medical and nursing personnel. In Greece, the Hellenic Navy has played a leading role in the introduction and development of HBO. "The Diving & Hyperbaric Medicine Unit" of the Athens Naval Hospital possesses one of the most sophisticated systems of recompression chambers worldwide. Specialized and experienced medical and nursing staff of the Unit serve as leading professionals on an international level. Although HBO facilities in Greece have increased during the last few years, continuous development in need of HBO is crucial to the needs of the population, the enhancement of diving tourism and better provision of health services for patients in hyperbaric conditions.
