Pulmonary barotrauma treatment7/14/2023 ![]() In the case of AGE in divers, the emboli are made up of gas in the arterial bloodstream resulting from lung overexpansion or pulmonary barotrauma (a physical injury to lung tissue resulting from pressure change). They can be composed of gas, blood clots, fat, tumors, amniotic fluid or bacterial vegetations. Their common origin is the process of decompression, but their underlying causes differ significantly.ĪGE is the disabling injury in 29 percent of dive fatalities and is likely associated with insufficient gas supply, which is the trigger in about 41 percent of dive accidents.1 Emboli are actual or potential blockages of blood vessels by foreign material. Collectively, these conditions are often lumped together and referred to as decompression illness (DCI). Under the right circumstances this can initiate a complex interplay between physics and physiology that leads to injury.ĭivers face two types of decompression-related injury: decompression sickness (DCS) and arterial gas embolism (AGE). Whether ascending from depth or traveling to high altitudes, as we move outward and upward from Earth’s center, the ambient pressure decreases.
