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 ...
Air is able to travel to the soft tissues of the neck from the mediastinum and the retroperitoneum (the space behind the abdominal cavity) because these areas are connected by fascial planes. [4] From the punctured lungs or airways, the air travels up the perivascular sheaths and into the mediastinum, from which it can enter the subcutaneous ...
In the presence of a right-to-left shunt of the heart, such as a patent foramen ovale, venous bubbles may enter the arterial system, resulting in an arterial gas embolism. [ 12 ] [ 13 ] A similar effect, known as ebullism , may occur during explosive decompression , when water vapour forms bubbles in body fluids due to a dramatic reduction in ...
Decompression sickness (DCS; also called divers' disease, the bends, aerobullosis, and caisson disease) is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during decompression.
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [1] [2] The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by an expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the ...
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.
While most people typically carry about 10% to 15% visceral fat, having more than that can significantly increase the risk of chronic health conditions like heart disease, diabetes and even cancer.
Thromboembolism – embolism of thrombus or blood clot. [1] Cholesterol embolism - embolism of cholesterol, often from atherosclerotic plaque inside a vessel. Fat embolism – embolism of bone fracture or fat droplets. [1] Air embolism (also known as a gas embolism) – embolism of air bubbles. [1] Septic embolism – embolism of pus containing ...
