Barotrauma

barotrauma

Barotrauma is an injury that happens when there is a harmful difference in pressure between the inside of the body and the outside environment. It most often affects places that contain air, such as the ears, sinuses, lungs, and dental spaces; when external pressure changes quickly, those air spaces can be squeezed or over-expanded and cause tissue damage. Symptoms depend on the area involved but commonly include pain, a feeling of fullness, hearing changes, nosebleed, shortness of breath, or swelling, and more serious cases can lead to dangerous air leaks in the chest. Sudden pressure changes during diving, flying, or rapid altitude shifts are common causes, and trying to force breathing or movement against trapped air raises the risk. Preventing barotrauma involves simple habits like equalizing pressure early and often, ascending and descending slowly, avoiding travel when congested, and using proper breathing techniques. People with certain medical conditions or recent surgeries should get medical advice before exposing themselves to rapid pressure changes. Treatment ranges from rest and pain relief to oxygen therapy, medications, or procedures when severe. Understanding how pressure affects the body and taking basic precautions makes barotrauma largely preventable for most people.
