![]() If the diver does even a single breath of air or other gas at a depth and does not let him free to come out on ascent, the expanding gas can over-express the lungs. The ear barotrauma is about 1/3 of all the injuries of the divers. The risk increases in any condition that may interfere with pressure equalization (for example, sinusitis, auditory tube block, congenital anomalies, infectious process) in air-containing body cavities. The highest risk of barotrauma begins at a depth of 30 feet. Compliance with safety rules for scuba diving and preventive use of decongestants can reduce the likelihood of barotrauma. If, following a light barotrauma, arterial gas embolism develops, recompression therapy (in a pressure chamber) is indicated. ![]() Barotrauma treatment in most cases is supportive, but can include decongestants) and analgesics for barotrauma of ears and sinuses, or inhalation of O and drainage of the pleural cavity with pneumothorax. The diagnosis is established clinically, but sometimes requires visualization methods of investigation. Disturbances of breathing and loss of consciousness threaten life and can develop due to rupture of alveoli and pneumothorax. ![]() Symptoms may include pain in the ears, dizziness, hearing loss, pain in the paranasal sinus, nosebleeds and abdominal pain. There is damage to airborne cavities, including the lungs, ears, accessory sinuses, gastrointestinal tract, air cavities in the teeth and space under the mask of a diver. ![]() Barotrauma - tissue damage caused by a change in the volume of gases in the body cavities associated with a change in pressure. ![]()
