The amount of gas dissolved in a liquid is described by Henry's Law, which indicates that when the pressure of a gas in contact with a liquid is decreased, the amount of that gas dissolved in the liquid will also decrease proportionately. On ascent from a dive, inert gas comes out of solution in a process called "outgassing" or
Air can be trapped under the skin in necrotizing infections such as gangrene, occurring as a late sign in gas gangrene, [2] of which it is the hallmark sign. Subcutaneous emphysema is also considered a hallmark of Fournier gangrene. [26] Symptoms of subcutaneous emphysema can result when infectious organisms produce gas by fermentation. When ...
Bubbles which are carried back to the heart in the veins will pass into the right side of the heart, and from there they will normally enter the pulmonary circulation and pass through or be trapped in the capillaries of the lungs, which are around the alveoli and very near to the respiratory gas, where the gas will diffuse from the bubbles ...

Air trapping, also called gas trapping, is an abnormal retention of air in the lungs where it is difficult to exhale completely. [1] It is observed in obstructive lung diseases such as asthma , bronchiolitis obliterans syndrome and chronic obstructive pulmonary diseases such as emphysema and chronic bronchitis .
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 ...
