A2 - Loscalzo, Joseph PY - 2018 T2 - Harrison's Principles of Internal Medicine, 20e AB - Hyperbaric medicine is the treatment of health disorders using whole-body exposure to pressures >101.3 kPa (1 atmosphere or 760 mmHg). In practice, this almost always means the administration of hyperbaric oxygen therapy (HBO2T). The Undersea and Hyperbaric Medical Society (UHMS) defines HBO2T as: “a treatment in which a patient breathes 100% oxygen … while inside a treatment chamber at a pressure higher than sea level pressure (i.e., >1 atmosphere absolute or ATA).” The treatment chamber is an airtight vessel variously called a hyperbaric chamber, recompression chamber, or decompression chamber, depending on the clinical and historical context. Such chambers may be capable of compressing a single patient (a monoplace chamber) or multiple patients and attendants as required (a multiplace chamber) (Figs. S11-1 and S11-2). Historically, these compression chambers were first used for the treatment of divers and compressed air workers suffering decompression sickness (DCS; “the bends”). Although the prevention and treatment of disorders arising after decompression in diving, aviation, and space flight has developed into a specialized field of its own, it remains closely linked to the broader practice of hyperbaric medicine.
