Prior to 1980, there was an
organization known as "Leofast", located
at Brooks A.F.B., TX , where divers consulted with hyperbaric
physicians
concerning possible diving injuries.
In the twelve years prior to 1980 there
were 62 cases of DCS reported
and described . Here are some of the suspected causes of the illnesses
thought to be DCS:
- Exceeded No-decompression limits
- Running out of air, rapid ascent
- Diving on the edge of No-decompression limits
- Deep or repetitive dives using computer outside the limits
of the tables
or no-decompression limits
- Diving at altitude
- Vigorous exercise before and after a dive
There are other factors that are
thought to increase the chances of
getting DCS but have little data in support; some of these are:
- Age; risk increases in proportion to increase in age
- Obesity
- Sex ? (Possibly more frequent in females )
- Fatigue, Hard physical work
- Dehydration, due to any cause (coffee, oral diuretics,
alcohol, vomiting
and diarrhea states, failure to drink non-alcoholic liquids)
- Alcohol and hangover state (related to dehydration)
- Medical problems increasing the viscosity of the blood (Sickle
cell
anemia and trait)
- Injury to muscle, bone or joint (due to increased blood flow
to inflamed
area)
- Rate of ascent
- Repetitive, multiday dives after a long lay-off; deep
prolonged air
diving
- Failure to do safety stops
- Patent foramen ovale
- Smoking habits
- Adaptation or recent diving history
- Conditioning
- Underestimated depth
- Table "fudging"
There is no good evidence that shows
that a hot shower after diving
increases the rate of decompression sickness.
Some believe that the use of aspirin might help prevent the
adherence
of blood platelets to bubbles, thereby reducing the chance of bubble
damage.
