To prevent the excess formation of bubbles that can lead to decompression sickness, divers limit their ascent rate—the recommended ascent rate used by popular decompression models is about 10 metres (33 ft) per minute—and follow a decompression schedule as necessary. [82]
Decompression sickness is usually avoidable by following the requirements of decompression tables or algorithms regarding ascent rates and stop times for the specific dive profile, but these do not guarantee safety, and in some cases, unpredictably, there will be decompression sickness.
A decompression stop is the period a diver must spend at a relatively shallow constant depth during ascent after a dive to safely eliminate absorbed inert gases from the body tissues sufficiently to avoid decompression sickness. The practice of making decompression stops is called staged decompression, [13] [21] as opposed to continuous ...
If the pressure reduction is sufficient, excess gas may form bubbles, which may lead to decompression sickness, a possibly debilitating or life-threatening condition. It is essential that divers manage their decompression to avoid excessive bubble formation and decompression sickness.
Starting decompression while bubbles are present appears to be the triggering factor in many cases of otherwise unexpected decompression sickness during routine saturation decompression. [ 84 ] Application of a bubble model in 1985 allowed successful modelling of conventional decompressions, altitude decompression, no-stop thresholds, and ...
Bubble decompression models are a rule based approach to calculating decompression based on the idea that microscopic bubble nuclei always exist in water and tissues that contain water and that by predicting and controlling the bubble growth, one can avoid decompression sickness. Most of the bubble models assume that bubbles will form during ...
Ways to avoid heater sickness. If you want to reduce your risk of getting heater sickness, experts recommend the following: Choose the right filters.
Decompression sickness is a condition caused by dissolved gases coming out of solution as bubbles in the tissues and fluids of the body during and directly after depressurisation. DCS is best known as a hazard of underwater diving but may occur in other decompression events such as caisson work, flying in unpressurised aircraft, and extra ...
