hyperbaric injury

Show Summary Details

Quick Reference

Exposure to environments greatly exceeding normal atmospheric pressure, e.g., in deep sea diving or a hyperbaric chamber, can cause a variety of vascular injuries, including intraocular damage impairing eyesight and intracranial damage, such as cerebral hemorrhage, if the pressure is increased too rapidly. Middle ear and paranasal sinus damage also occurs. Nitrogen narcosis due to greatly increased dissolved nitrogen concentration in serum is a dangerous condition among deep sea scuba divers. Barotrauma is a risk if the pressure is subsequently reduced to normal too rapidly.
