模拟氦氧480m饱和-493m巡回潜水研究

Research on the simulated heliox 480 m saturation-493 m excursion dive

目的 获取人体在高压耐受极限区域的潜水实验数据,完善相关医学保障措施.方法 由9名海军潜水员参与饱和深度65 ～480 m的系列氦氧模拟饱和潜水,采用改进的潜水程序、强化的医学监护措施和针对性的医学干预完善医学保障措施,并进行潜水员能力评价.结果 首次成功应用了建立在气泡学说基础上的我国饱和减压方案,证实了代谢组学在高气压环境下全面、无创性医学监护的优势,成功运用药物干预减轻了损伤性负荷,建立了压力敏感型人员的有效鉴别手段.结论 该研究取得的成果将丰富和深化高气压生理学内涵,为大深度潜水实践提供有效指导.

Objective To acquire related data of a deep saturation dive which approaches the depth limit in terms of physiology,and to further improve medical service for such dives.Methods A series of simulated heliox saturation dives （saturation depths,65-480 m） were conducted by 9 naval divers.During the experiments,modified diving procedures,intensified medical surveillance measures,targeted medical intervention and performance evaluation were applied to ensure the success of the dive.Results Following research results were obtained：the decompression profile based on the bubble theory was developed and applied in a series of diving experiments ; the superiority of urine metabonomics in full-scale and noninvasive medical detection of divers at high pressure was demonstrated; pharmacological intervention was used to alleviate harmful loads; and effective identification means were established to distinguish pressure susceptible people.Conclusions The research results obtained from this project would enrich and deepen intimate knowledge on hyperbaric physiology and would be a good guidance for better medical supports in deep saturation dives.
