模拟3～50m快速上浮脱险训练潜艇艇员血压、脉率和呼吸频率的变化

Changes of blood pressure,pulse rate and respiratory rate in submariners following simulated air breathing 3-50 m fast buoyancy ascent escape training

目的 观察模拟快速上浮脱险训练时潜艇艇员生命指征的变化.方法 分别进行了3、10、30、50 m 4个深度69人次的快速上浮脱险训练,于训练前、训练后即刻及出舱后10 min分别测定艇员的血压、脉率和呼吸频率.结果 训练后即刻艇员的收缩压、舒张压、脉率及呼吸频率与进舱前比较,绝大部分指标有所增加,差异有统计学意义（p〈0.01）.在出舱后10 min各指标基本恢复正常.结论 模拟快速上浮脱险训练可增加艇员血压、脉率和呼吸频率,但均为一过性.本次脱险训练方案是安全可靠的.

Objective To observe effects of simulated air-breathing fast buoyancy ascent escape training on the vital signs of submariners.Methods A series of escape training,totaling 69 man-times were carried out at different depths of 3,10,30 and 50 m.Blood pressure,pulse rate and respiratory rate of the submariners were measured before training.the moment after termination of training and 10 min after surfacing from the escape chamber.Results When compared with those of pre-training,most of the indices concerning systolic pressure,diastolic pressure,pulse rate and respiratory rate of the submariners increased quite significantly,with statistical differences （P〈0.01） the moment after termination of training.Nevertheless,the values almost returned to normal,10 minutes after training.Conclusions Simulated air-breathing fast buoyancy ascent could elevate blood pressure,pulse rate and respiratory rate of submariners.However,these changes were all transient.The profile of our submarine escape training proves to be safe and reliable.
