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.
Even without producing acute signs and symptoms, vascular gas bubbles can be an indicator of the magnitude of decompression stress, and as most dives where gas bubbles form only produce minimal symptoms, they may be useful as an indicator of the risk of injury in a particular dive, and therefore could be useful to help develop safer procedures.
DCI can be caused by two different mechanisms, which result in overlapping sets of symptoms. The two mechanisms are: Decompression sickness (DCS), which results from metabolically inert gas dissolved in body tissue under pressure emerging out of solution and forming bubbles during decompression. It typically afflicts underwater divers on poorly ...
[104] [105] It is the definitive treatment for severe decompression sickness, which is largely a condition involving localized hypoxia initially caused by inert gas embolism and inflammatory reactions to extravascular bubble growth. [106] [107] [108] It is also effective in carbon monoxide poisoning [109] and diabetic foot. [110] [111]
Gas is breathed at ambient pressure, and some of this gas dissolves into the blood and other fluids. Inert gas continues to be taken up until the gas dissolved in the tissues is in a state of equilibrium with the gas in the lungs (see saturation diving), or the ambient pressure is reduced until the inert gases dissolved in the tissues are at a higher concentration than the equilibrium state ...
Other signs your cold is improving include mucus color, energy levels and less severe symptoms. Know the stages of a cold. ... A cold is an infection caused by over 200 respiratory viruses, but ...
Onset of symptoms: Here, you start experiencing the first signs of a cold, such as a sore throat, sneezing, and mild fatigue. This stage marks the body’s initial immune response to the infection.
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 ...
