12只杂种狗分成6组各2只。从股动脉放血至MAP5.3kPa后一直维持这一水平,根据贮血瓶内血液开始回灌和回灌最大失血量的30%将休克过程分为代偿期、失代偿期和不可逆期。实验组在失代偿后进行声门外高频喷射通气(HFXV)。进入不可逆期夹闭动脉停止血液回灌,再观察120min结束。实验结果:两组动物的代偿间期分别为
Twelve hybrid dogs were divided into 6 groups of 2 each. From the femoral artery to MAP5.3kPa blond after this level has been maintained, according to blood storage bottle blood began to recharge and recharge the maximum blood loss of 30% of the shock process is divided into decompensated, decompensated and irreversible. The experimental group was decompensated after the sound-gate high-frequency jet ventilation (HFXV). Into the irreversible occlusion of the artery to stop blood reperfusion, and then observe the end of 120min. Experimental results: Two groups of animals were compensatory intervals
