摘要
目的通过计算新的深度-时程氦氧常规潜水减压方案,为有效提高大深度氦氧常规潜水训练效率提供依据。方法按照Haldane计算潜水减压表的经典模型,采用原计算60~120 m氦氧常规潜水减压表的过饱和安全系数,计算80、100和120 m/15 min 3种深度-时程的氦氧常规潜水减压方案;结合训练进行验证。结果3种方案的减压总时间分别比相应深度/20 min方案缩短20、31和36 min;经54人次氦氧常规潜水验证,未出现减压病症状。结论水下工作时间以5 min为一档,建立新的氦氧常规潜水减压表,可在保障潜水员安全的基础上有效提高潜水训练效率。
Objective To calculate a new depth-time heliox conventional diving decompression scheme for improving the training efficiency of deep heliox conventional diving.Methods Based on the classical calculation model of Haldane’s diving decompression scheme,we used its supersaturation safety coefficient for 60-120 m heliox conventional diving decompression scheme,calculated the decompression schemes for 80 m/15 min,100 m/15 min,and 120 m/15 min depth-time diving,and verified them by training.Results The total decompression time of the three schemes were shortened by 20,31,and 36 min respectively than those of the depth/20 min scheme at the same depth.After 54 person/times heliox conventional diving trials,no decompression sickness symptoms were found.Conclusion A new heliox conventional diving decompression scheme with every 5 minutes as an interval for underwater operation can effectively improve the diving training efficiency while ensuring divers’safety.
