补充资料：胸膜腔负压
胸膜腔负压
胸膜腔内的压力小于大气压。习惯上称为"胸内负压"。平静呼气末期约为－0．3999～0．6665 kPa(－3～5mmHg），吸气末期为－0．6665～1．333kPa(－5～10mmHg）。胸内负压是由作用于胸膜表面的压力间接形成的。当肺处于静止状态时，作用于胸膜内层表面的压力有两种：其一是肺泡内的压力，这与大气压相等，这种压力迫使肺泡扩张；其二是肺组织由于被动扩张而产生的弹性回缩力，力的作用方向与肺泡内压相反。因此胸膜腔内压力实际反映了这两种作用力的关系，即大气压减去弹性回缩力。假如肺的弹性回缩力是0.6665kPa(5mmHg），则胸内压应是103.3080kPa－0．6665kPa＝102．6415kPa(760mmHg－5mmHg=755mmHg），较大气压低0．6665kPa(5mmHg），可以用一0．6665kPa(一5mmHg）表示胸内压。任何情况造成胸膜破坏，空气都将进入胸膜腔内，形成气胸。
