Decompression sickness practices in lobster diving among the indigenous Miskito people, who face great economic pressures. At that time it was estimated that in the country over 2000 divers had been injured and 300 others had died since the 1970s. In the United States, it is common for medical insurance not to cover treatment for the bends that is the result of recreational diving. This is because scuba diving is considered an elective and "high-risk" activity and treatment for decompression sickness is expensive. A typical stay in a recompression chamber will easily cost several thousand dollars, even before emergency transportation is included.
Decompression practice The no decompression limit (NDL) or no stop time, is the interval that a diver may theoretically spend at a given depth without having to perform decompression stops. The NDL helps divers plan dives so that they can stay at a given depth and ascend without stopping while avoiding unacceptable risk of decompression sickness. The NDL is a theoretical time obtained by calculating inert gas uptake and release in the body, using a model such as the Bühlmann decompression algorithm. Although the science of calculating these limits has been refined over the last century, there is still much that is
