Decompression Sickness

Alternate Names : Decompression Illness, Caisson Disease, The Bends

What can be done to prevent the disease?

The best way to prevent this condition is to limit the depth and duration of scuba dives. Short, shallow dives do not require what is called decompression. Decompression involves stopping and waiting for a period of time at different depths as one rises to the surface. This allows the extra dissolved gases that build up to escape through the lungs as the person breaths. This prevents too many gas bubbles from forming. Using proper decompression can prevent decompression sickness entirely after deeper or longer dives.

In addition, the time between dives should be more than 12 hours. A person should spend at least 24 hours at the surface before going to an increased altitude, which includes flying.

What are the long-term effects of the disease?

If treatment is given right away, there are often no long-term effects. Permanent bone damage, chronic pain, brain damage leading to paralysis or other problems, and even death may occur in untreated or severe cases.

What are the risks to others?

Decompression sickness is not contagious and poses no risks to others.
