Air embolisms are a serious medical condition that occurs when air bubbles enter the bloodstream and cause blockages. Other terms for air embolisms include gas embolisms, pneumobaropathy, and pulmonary barotrauma. Gas embolisms can be caused by medical procedures, diving accidents, or traumatic injuries. Pneumobaropathy is a type of gas embolism that occurs when changes in air pressure cause bubbles to form in the body. Pulmonary barotrauma is a specific type of gas embolism that affects the lungs and can cause serious respiratory distress. Regardless of the terminology used, air embolisms require immediate medical attention to prevent serious complications.
