Injuries caused by rapid decompression are called barotrauma , and are well known from scuba diving accidents. 13. In most cases of sinus barotrauma , localized pain to the frontal area is the predominant symptom. 14. Yelloweye brought to the surface by fishing boats tend to die of decompression barotrauma and temperature shock. 15. Equalising ( or clearing ) the ears is necessary to prevent barotrauma to the middle and inner ear. 16.

The cause of death was listed as barotrauma , which occurs when there is a huge shift in pressure. 18. Bats can be killed by lung barotrauma when flying in low pressure regions close to operating wind turbine blades. 19. A significant part of entry level diver training is focused on understanding the risks and procedural avoidance of barotrauma . 20. Failure to equalise the pressure inside the mask may lead to a form of barotrauma known as mask squeeze.
