目的 为提高海军部队的防险救生能力 ,培养一批适应大深度饱和潜水的潜水员和从事相应深度的潜水医学保障及设备保障人员。方法 8名海军潜水员 ,在氧分压值为 (4 0± 2 ) k Pa与 140 m氦氧混合气环境的居住舱内饱和 48h,并在此期间 6次巡回潜水到 16 4～ 16 6 m海底 ,有效完成了预定的水下作业任务 ,最后 ,经 149h 2 0 min减压 ,安全返回常压。根据现场条件 ,在全面临床体检和常规指标检查的基础上 ,在潜水过程的不同阶段分别进行了神经、心理、呼吸、心血管、免疫、应激、运动及平衡、听觉等各系统功能的医学、生理学及生物化学等指标的检测。结果 在饱和 -巡潜阶段 ,潜水员普遍存在焦虑、恐怖或抑郁表现 ;肺功能最大通气量 (MVV )随深度增加呈显著降低 ;滚珠投递准确率明显降低 ;ACTH、皮质醇等应激激素水平显著提高。结论 本次医学保障措施切实有效 ,使潜水达到了预期目的 ,机体所出现的变化均为暂时的和可逆的
Objectives To enhance the anti-life and rescue capabilities of the naval forces and to foster divers who can adapt to deep, deep-dive and diversionary medical insurance and equipment support personnel. Methods Eight navy divers were saturated for 48h in the habitat with oxygen partial pressures of (40 ± 2) k Pa and 140 m heliox. During this period, six naval divers were diverted to 16 4-16 6 m Seabed, the effective completion of the scheduled underwater task, and finally, decompression after 149h 2 0 min, safe return to atmospheric pressure. According to the site conditions, on the basis of comprehensive examination of clinical physical examination and routine indexes, the medicine of various system functions such as nerve, psychology, respiration, cardiovascular, immune, stress, exercise and balance, hearing and so on were performed at different stages of the diving process , Physiology and biochemistry and other indicators of detection. Results During the saturation-patrolling stage, divers generally experienced anxiety, horror or depression. MVV significantly decreased with increasing depth, and ball delivery accuracy decreased significantly. The levels of ACTH, cortisol and other stress hormones were significant improve. Conclusion The medical safeguard measures are effective and effective, so that the diving has achieved its intended purpose. The changes in the body are temporary and reversible
