  失血量的判断
  Determination of blood loss
  如失血量超过全身血容量的20%(约800毫升)以上时可出现轻度休克症状:伤员口渴、面色苍白、出冷汗脉搏快而弱、可达每分钟100次以上。
  If the blood loss is more than 20% (about 800 ml) of the whole body blood volume, mild shock symptoms may occur: the wounded are thirsty, pale, sweating, and the pulse is fast and weak, reaching more than 100 times per minute.
  如出血量为总血量的20%-40%(800——1600ml)时,可能会出现中度休克症状:呼吸急促、烦躁不安、脉搏可达每分钟100次以上。
  If the amount of bleeding is 20% - 40% (800-1600ml) of the total blood volume, moderate shock symptoms may occur: shortness of breath, irritability, pulse can reach more than 100 times per minute.
  如出血量达总血量的40%(1600ml)以上时可能出现重度休克症状:伤员表情淡漠、脉搏细弱或摸不到,血压测不清随时可能危及生命。
  If the amount of bleeding is more than 40% (1600ml) of the total blood volume, severe shock symptoms may occur: the wounded's expression is indifferent, the pulse is weak or can not be touched, the blood pressure can not be measured clearly, and it may be life-threatening at any time.
  因此,止血是抢救出血伤员的一项重要措施,它对挽救伤员生命具有特殊意义。
