리의 생리적 특징, 즉 헤모글로빈 완충작용 때문에 공급되 는 산소농도가 60-120 mmHg 사이로 변한다 해도조직에 공급되는 산소농도는 일정하게 유지될 수 있다. 정상기압에 서 혈장 용존 산소는 단지 100 mL의 혈액 중 0.3 mL(이를 volumes perscent [vol%]라고 한다)이며, 반면에 헤모글로 빈에 의한 것은 20 mL (20vol%)이다. 기압을 3기압으로 올 리면 PaO2는 2,200 mmHg에 달하며 이는 혈장 용존 산소 량은 5.4vol%로써 정상 0.3vol%의 18배 정도까지 증가하게 된다. 그러므로 이렇게 높아진 산소분압은 헤모글로빈이 완 전히 없어도 기초대사기능을 지속적으로 유지시킬 수 있는 Hyperbaric oxygen therapy (HBOT) is approved in the United States for 14 accepted indications, which are approved by the HBOT committee of the

HBOT is a mode of medical treatment in which the patient is situated in an enclosed pressure chamber and breathes 100% oxygen at a pressure greater than 1 atmosphere absolute (ATA), with the usual therapeutic pressure set at greater than 1.4 ATA. In South Korea, an expanded knowledge base and formalized education in HBOT do not exist, and numerous HBOT devices are old and nearing the cessation of operation, although HBOT has undergone refinement, with an increased understanding of mechanisms of action and clinical applications. Furthermore, there is no specific board certification of HBO competence for emergency, critical care, and surgical physicians and technicians in South Korea. We summarize the existing literature on the uses of HBO with the aim of enhancing the understanding of this therapeutic technique.
