Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
If these bubbles cause blockage in blood vessels, this is arterial gas embolism. Vascular obstruction and inflammation caused by gas bubbles causes end organ damage to most tissues. [15] Sufficient pressure difference and expansion to cause this injury can occur from depths as shallow as 1.2 metres (3.9 ft). [16]
The air may then enter the arterial circulation producing arterial gas embolism (AGE), with effects similar to severe decompression sickness. [7] Although AGE may occur as a result of other causes, it is most often secondary to PBT. AGE is the second most common cause of death while diving (drowning being the most common stated cause of death ...
DCS often causes air bubbles to settle in major joints like knees or elbows, causing individuals to bend over in excruciating pain, hence its common name, the bends. Individual susceptibility can vary from day to day, and different individuals under the same conditions may be affected differently or not at all.
The tissues in the mediastinum will slowly resorb the air in the cavity so most pneumomediastinums are treated conservatively. Breathing high flow oxygen will increase the absorption of the air. If the air is under pressure and compressing the heart, a needle may be inserted into the cavity, releasing the air.
Pleurisy can be caused by a variety of conditions, including viral or bacterial infections, autoimmune disorders, and pulmonary embolism. The most common cause is a viral infection. [2] Other causes include bacterial infection, pneumonia, pulmonary embolism, autoimmune disorders, lung cancer, following heart surgery, pancreatitis and asbestosis ...

Gas bubble formation in blood vessels causes obstruction and inflammation, and platelet aggregation may occur. [11] In more solid tissues there may be mechanical damage, and the presence of mobile bubbles in the fluids of the inner ear may cause abnormal stimuli. The pathogenesis remains elusive, [13] and may have more than one mechanism ...
