As many divers know, decompression illness (DSI) is treated by recompression with hyperbaric oxygen therapy in hyperbaric chambers. Intervascular and tissue bubbles cause DCI. Compression in a chamber immediately reduces bubble volumes, which can restore blood flow and decrease tissue injury. Furthermore, the inhalation of hyperbaric oxygen accelerates nitrogen elimination from these bubbles.
But hyperbaric oxygen is also used to treat several non-dive related disorders.
Hundreds of years ago, the Incas recognized that descending to lower altitudes improved the healing of wounds. Increasing barometric pressure with excursion to a lower altitude elevates blood and tissue oxygen levels.
Clinical hyperbaric oxygen treatment dates back to work by a cardiovascular surgeon, Dr. Ite Boerema in the Netherlands. In 1959 he published a paper entitled "Life without blood". His work showed that, due to sufficient oxygen dissolved in plasma during hyperbaric oxygen exposure, piglets could survive without blood.
This pioneering research led Boerema's team to successfully perform open-heart surgery on patients while compressed in a large chamber. With the patient's oxygen needs provided by hyperbaric oxygen therapy, the patient's heart could be stopped, allowing doctors to repair it.
To follow up on Boerema's experience, several hyperbaric oxygen medical chambers were built in the 1960s.
With the advent of membrane oxygenators and otrer advances in cardiovascular surgery, hyperbaric oxygen was abandoned for open-heart surgery.
However, most chambers exist to treat patients with conditions of oxygen deprivation. This includes carbon monoxide poisoning, severe infections and non-healing ischemic wounds, wich result from the obstruction of blood flow.
