通过从股静脉将漂浮导管插入肺动脉的方法 ,检测悬挂前、悬挂期间和临终阶段呼吸、肺动脉压、心输出量的变化,探讨体位性窒息对心、肺功能影响及其在死亡中所起作用。结果:(1)悬挂前呼吸频率平稳 ,悬挂期间逐渐加快 ,临终前呈无规律状态 ;(2)悬挂期间及临终时肺动脉压比悬挂前明显升高;(3)悬挂前及悬挂期间的心输出量基本平稳 ,临终时比悬挂前及悬挂期间明显下降。本研究发现 ,悬挂可致呼吸失调 ,机体缺氧 ,导致心、肺功能障碍 ,属肺性死亡。其特征为呼吸停止是原发性的 ,心跳停止是继发的。
The floating catheter was inserted into the pulmonary artery from the femoral vein to detect the changes of respiration, pulmonary artery pressure and cardiac output before, during and after the suspension, and to investigate the influence of postural asphyxia on heart and lung function and its role in death . Results: (1) The respiration frequency before the suspension was steady and gradually increased during the suspension. The symptoms were dominating before the dying. (2) The pulmonary pressure increased significantly before and during the suspension. (3) The heart before and during the suspension Output is basically stable, dying than before hanging and hanging down significantly. This study found that suspension can cause respiratory disorders, hypoxia, leading to heart and lung dysfunction, a pulmonary death. It is characterized by respiratory arrest is primary, cardiac arrest is secondary.
