Marine medicine, also called undersea medicine or diving medicine is the diagnosis, treatment & prevention of hamper caused by human under water. The effects on the body of pressure ,the diagnosis & treatment of problems due to marine hazards ,divers fitness & safety are including with this topic.
marine medicine
Depth & Pressure Effects:
Usually diving illness & accidents are occurred due to the effects of depth & pressure on gases in the human body. Decompression sickness, nitrogen narcosis, arterial gas embolism& oxygen toxicity are the examples. The example of the effects on the bones & joints is Dysabric osteonecrosis.
Marine Hampers:
Dangers under water can affect divers. Marine life, marine infection, ocean current, polluted water are the marine hazards. There are also man made hazards like: fishing lines,boat,underwater construction etc. Diving medical team need to recognize & able to treat large & small poisonous creature, perfectly diagnosis & treat marine infection & illness. Also have to conscious about sea sickness, malaria etc.
Diving Fitness:
All divers have to be free of condition & illness that can be effect negatively on their safety & under water performance. The diving medical physicians have to trace, treat & advice divers about causes of risk under water & illness.
decompression illness
The Reasons why a people should not be allowed to dive are:
Disorders that causes altered condition.
Disorders that hamper the “neutral evolution of Boyle’s Law”.
Disorders that may causes irresponsible behavior.
Hyperbaric Treatment:
For the divers who stayed too long under water & affected by decompression sickness, hyperbaric chamber treatment was initially used for them. But now it is found that, it has been highly effective in the treatment of many problems where the administration of oxygen is beneficial. Research has proved that it to be very effective in almost 13 indications approved by undersea and hyperbaric medical society.

When you breathe in high pressure gas it gives you a lot of dangers.Something always should me kept in mind due to breathing high pressure gas. These are also briefed to the novices.
dangers of breathing high pressure in Gas
Decompression Sickness
This is formation of gas bubbles is blood due to sudden pressure decreases. It happens while ascending quickly. Here the gas trapped in blood wants to leave the body quickly & thus bubbles form. This is avoided by doing safety stops or decompression stops & ascending slowly using dive computers or decompression chart. This should be treated in a decompression chamber. Delivering oxygen riched air or pure oxygen to the affected diver is good first ,but even fatality or permanent disability may occur.

Nitrogen Narocosis
Due to breathing under huge depth, Narcosis occurs. Here the diver feels live alcoholic effect. Lose of consciousness, impair judgement, lack of concentration can occur. At greater depth hellacinogenic reaction 7 tunnel vision can occur. It’s mechanism of nitrogen Narcosis is similar to laughing GAS. It can be avoided by using Trimix or heliox.
nitrogen-narcosis
Oxygen Toxicity
It occurs when oxygen in body crosses a safe “partial pressure”(PPO2).it may affect the central nervous system 7 result as the drowning & spitting out the regulator. It is avoided by not descending below the safety level depth of given gas.
