Who Gets DCI?
Decompression illness can affect the scuba divers, the aviators, the astronauts and the compressed-air workers. It happens in about 1,000 U.S. scuba divers annually. Furthermore, DCI strikes randomly. The major risk factor for getting DCI is the reduction in ambient pressure, yet there exists other risk factors which can boost the possibility of DCI from taking place. These noted risk factors are usually the deep or long dives, the cold water, the hard exercise at depth, as well as the rapid ascents.
Such rapid ascents are strongly associated with a risk of AGE. Additional factors thought to maximize the risk of DCI however for which proof is not definitive are obesity, dehydration, a hard exercise just after surfacing, and also pulmonary disease. Moreover, there are individual risk factors which have not yet already been identified. This is the reason certain scuba divers tend to get DCI more often as compared to others despite the fact that they are following the very same dive profile.
Because DCI is a random occurrence, just about any dive profile can lead to DCI, regardless of how safe one may think. The reason is that often the risk factors, equally the known and the unknown, may control the likelihood of DCI in innumerable ways. As a result, assessment of diver for a possible decompression illness has to be done on a case-by-case basis through evaluating a diver’s signs and symptoms rather than just depending on the dive profile.
