模拟480m氦氧饱和潜水对潜水员情绪的影响

摘要

目的 研究0 ～480 m氦氧暴露和暴露时间对潜水员情绪的影响,为潜水员心理干预提供依据.方法 采用焦虑自评量表(SAS)、抑郁自评量表(SDS)、临床观察和晤谈法对不同大气压下的潜水员进行评估.结果 0 ～ 480 m高气压环境下潜水员焦虑(r=0.335,P=0.001)和抑郁症状(r=0.235,P=0.025)与大气压强呈正相关,差异有统计学意义；暴露时间与潜水员情绪变化无线性相关,差异无统计学意义(P＞0.05).无精神症状达阳性诊断标准的检出者,但各个实验阶段潜水员消极情绪的反应有所不同.结论 高气压氦氧暴露可对潜水员的焦虑、抑郁情绪产生动态性影响,应针对各个实验阶段潜水员主要的消极情绪进行心理干预.%Objective To study the effect of the 480 m simulated heliox saturation dive on the mood of divers and to provide evidence for psychological intervention.Methods The mood of the 4 divers exposed to different hyperbaric pressures were evaluated with SAS,SDS,clinical observations and personal interviews.Results The scores of SAS ( r =0.335,P =0.001 ) and SDS ( r =0.235,P =0.025 ) were positively correlated with the atmospheric pressures they exposed to,with a statistically significant difference.No linear correlation could be noted between the exposure duration and divers' mood,also without statistical significance.Although there were no positive detection of mental symptoms,different negative emotional reactions could be noted at various stages of the experiment.Conclusions Heliox exposure seemed to have dynamic effects on the anxiety and depression of divers.Psychological intervention in the divers should be directed in accordance with the divers' main negative emotional reactions at different experimental stages.
