Pulmonary barotrauma may result in a collapsed lung (pneumothorax). Diagnosis of barotrauma generally involves a history of exposure to a source of pressure which could cause the injury suggested by the symptoms. This can vary from the immediately obvious if exposed to explosive blast, or mask squeeze, to rather complex discrimination between possibilities of inner ear decompression sickness and inner ear barotrauma, which may have nearly id…

웹lung volume and lung hyperinflation as well, play a major role in barotrauma aetiology. Volutrauma is the term that describes ultrastructural lung injury due to overdistention occurring during mechanical ventilation.

This causes an increase intrathoracic pressure which at some point will cause structural damage – pneumothorax. There are some reports describing a development of pneumothorax in aviation.
웹Breath-hold diving involves highly integrative physiology and extreme responses to both exercise and asphyxia during progressive elevations in hydrostatic pressure.
