Extensive data concerning the incidence of decompression sickness among workers participating in the deepest caisson operation in Japan to date have been collected and analyzed for the period April through August, 1976. When the bottom pressure was between 3.0 and 3.2 ATA, the incidence of decompression sickness was 3.05%; subsequently, the incidence was only 0.96% between 3.2 and 3.4 ATA. The man lock (i.e., decompression chamber) had never been ventilated during the former group of decompressions and the level of CO2 had ranged between 1.8 and 2.3% (v/v); in the latter group of decompressions, the CO2 level ranged between 0.3 and 0.8% with ventilation. All other conditions, including the decompression table used, were the same. Moreover, based upon the nature of the muscular activity required of the caisson workers just prior to decompression, their most common site of affliction was found to lie within the body region where the highest tissue tensions of CO2 would be expected during decompression.
现已收集并分析了1976年4月至8月期间参与日本迄今为止最深沉箱作业的工人减压病发病率的大量数据。当底部压力在3.0至3.2ATA之间时，减压病发病率为3.05%；随后，在3.2至3.4ATA之间时，发病率仅为0.96%。在前一组减压过程中，人员闸室（即减压舱）从未进行过通风，二氧化碳水平在1.8%至2.3%（体积/体积）之间；在后一组减压过程中，通风时二氧化碳水平在0.3%至0.8%之间。所有其他条件，包括所使用的减压表，均相同。此外，根据沉箱工人在减压前所需肌肉活动的性质，发现他们最常见的患病部位位于减压过程中预计二氧化碳组织张力最高的身体区域。
