减压病是因机体在高气压环境下暴露一定时间后,由于减压速度过快,幅度太大,使机体组织和血液内溶解的中性气体游离成气泡而导致的一种特殊的职业性疾病。及时的单纯加压治疗急性减压病可使90％以上病例获得治愈。而病程超过24～48h得到良好结果的希望就少了。 Decompression sickness is due to the body exposed to high pressure environment for a certain period of time, due to the decompression speed too fast, the magnitude is too large, the body tissue and blood dissolved in the neutral gas into a bubble caused by a special occupation disease. Timely simple compression treatment of acute decompression sickness can make more than 90% of cases cured. The duration of more than 24 ~ 48h to get good results less hope.
