Anyone reporting signs or symptoms of decompression illness that began within 48 hours of scuba diving should be seen by a doctor at an emergency care facility immediately. The diver will need high-flow oxygen and IV fluids. Avoid hot tubs, saunas or hot baths after diving. This technique utilizes Oxygen. The risk of decompression illness is directly related to the depth of the dive, the amount of time under pressure, and the rate of ascent. Further treatments depend on how the diver responds to the initial treatment. Treatment can involve some simple lifestyle changes, which are often recommended as a preventative measure. One of the first steps would be to make sure there is no damage to the lungs. Decompression sickness (DCS; also known as divers' disease, the bends, aerobullosis, or caisson disease) describes a condition arising from dissolved gases coming out of solution into bubbles inside the body on depressurisation. State-of-the-art hyperbaric oxygen chamber by HyperTec. The diver will likely need to go to a hyperbaric chamber for recompression. Henry's law states that the solubility of gas in a liquid is directly … Observance of safety rules by a diver is vital for the prevention of caisson disease. Pain can occur at the head, neck, or torso. Do not fly within 24 hours after diving. 2. Caisson disease is an industrial hazard encountered in the building of bridges, tunnels and skyscrapers where compressed air is employed.

Blood tests can also be performed to measure cellular levels of immunoglobulin G and eosinophils, which usually mark the beginning of intestinal candidiasis. The nervous and musculoskeletal system are most often affected. DCS (also called the bends or caisson disease) results from inadequate decompression following exposure to increased pressure. Prognosis is good with hyperbaric oxygen treatment. In general, the longer a person waits to fly after diving, the lower the risk of developing decompression sickness.

The following actions increase risk of developing decompression illness: Prognosis or outlook of people who develop the bends varies with the following factors: Decompression sickness symptoms generally begin within 6-48 hours after diving. The bends are treated in a hyperbaric recompression chamber. DCS most commonly refers to problems arising from underwater diving decompression (i.e., during ascent), but may be experienced in other depressurisation events such as emerging from a caisson, flying in an unpressurised aircraft at high altitude, and extravehicular activityfro… For more complicated diving, waits of 48 hours have been recommended.
