模拟153m深度快速上浮脱险潜艇艇员血压、脉率和呼吸频率的改变

目的　观察大深度快速上浮脱险对潜艇艇员生命指征的影响。方法　分别进行了 3,10 ,6 0 ,80 ,10 0 ,12 0和 15 3m 4 0人次的快速上浮脱险实验 ,于脱险前和脱险后观察艇员血压、脉率及呼吸频率的改变。结果　脱险后 ,艇员收缩压、舒张压、脉率和呼吸频率均有所增加 ,在出舱后即刻为甚 ,大部分指标在出舱后即刻与进舱前相比较 ,差异有显著性 (P<0 .0 5 )或有非常显著性 (P<0 .0 1)。在出舱后 10min各指标基本恢复正常。在 10 0 ,12 0和 15 3m快速上浮脱险时第 1名艇员脉率改变持续较久 ,但最终也恢复正常。结论　快速上浮脱险可增加艇员血压、脉率和呼吸频率 ,但均为一过性。本次实验脱险方案是安全可靠的

Changes in blood pressure,pulse rate and respiratory rate in submariners after the 153 m simulated air-breathing fast buoyancy ascent

Objective To observe effects of great depth air breathing fast buoyancy ascent on the life signs. Methods A series of simulated air breathing buoyancy fast ascent were carried out at depths of 3, 10, 60, 80, 100, 120 and 150 m. Blood pressure, pulse rate and respiratory rate of the submariners were measured both before and after air breathing fast buoyancy ascent experiment. Results Systemic pressure, diastolic pressure, pulse rate and respiratory rate of the submariners all increased quite obviously following fast buoyancy ascent, especially the moment when they surfaced from the chamber. Most of the values of systemic pressure, diastolic pressure, pulse rate and respiratory rate at the moment when they surfaced were significant higher than those of the pre ascent ( P <0.01 or P <0.05). However, these values nearly returned to normal 10 minutes after they surfaced from the chamber. The change in the pulse rate of the first submariner lasted considerably longer during the 100, 120 and 153 m fast buoyancy ascents, and it also returned to normal without any significant ill effect. Conclusions The simulated air breathing buoyancy fast ascent escape can increase systemic pressure, diastolic pressure, pulse rate and respiratory rate of the submariners, but these changes were all transient. Experimental results prove that the fast buoyancy ascent escape profile is sound and safe.
