Which type of gases is more likely to contribute to gas dysbarism?

Gas dysbarism occurs when changes in atmospheric pressure cause gases dissolved in body tissues to form bubbles as they come out of solution. This condition is particularly relevant to aviation and diving, where significant pressure changes can be experienced.

Evolved gases, which refer to gases that come out of solution due to decreased pressure, can lead to gas dysbarism as they form bubbles in the body. Trapped gases, on the other hand, are gases that have been sealed within tissues or cavities of the body and may also expand rapidly when pressure drops. Both types of gases can result in bubble formation during decompression.

The combination of evolved and trapped gases is particularly important because they can both have detrimental effects during rapid ascent or decompression, making both types significant contributors to gas dysbarism. Therefore, recognizing that both evolved and trapped gases are linked to this condition is essential in understanding the risks associated with rapid changes in pressure in aviation and diving activities.
