美国国家研究委员会在1951年的专著《减压病》中说潜水员中未发现本病。近年来情况大变,因为急性减压病较易预防,而本病却在逐年增加。据英国减压病中央登记处报告,本病在英国工商业潜水员中的总患病率,1975年为0.9％,1979年为4.8％,原因之一是潜水深度和时间增加,潜水超过200米的为15.8％,超过300米的饱和潜水为22％。由于开发海洋资源是“第四次工业革命”中五大项目之一,我国正在大规模地开采海底石油,在此项作业中,潜水员是关键性工种之一,因此必须做好预防工作,但目前尚缺乏有把握的预防办法。英国学者的潜水医学水平较高(保持着海平面下686米饱和潜水的世界记录),与法国,美国相比,饱和潜水后的减压时间最长,但仍有较高的患病率。近年来随着多普勒超声气泡探测仪的应
The National Research Council said in a 1951 monograph “Decompression Disease” that the disease was not found in the divers. In recent years the situation has changed dramatically, because acute decompression sickness is easier to prevent, but the disease is increasing year by year. According to the British Registry of Central Decompression, the overall prevalence of this disease in commercial and industrial divers in the United Kingdom was 0.9% in 1975 and 4.8% in 1979. One of the reasons for this is the increased diving depth and time, the diving of more than 200 meters 15.8%, saturated diving more than 300 meters was 22%. Since the development of marine resources is one of the five major projects in the “Fourth Industrial Revolution,” our country is exploiting large-scale offshore oil. Divers are one of the key types of work in this operation. Therefore, preventive measures must be taken, but at present, There is a lack of a clear and sure way to prevent it. British academics have a high level of diving medicine (keeping a world record of 686 meters of saturated diving at sea level). Compared with France and the United States, the decompression time after saturation diving is the longest, but there is still a high prevalence rate. In recent years, with the Doppler ultrasound bubble detector should
