  5. Relax: if the bleeding is serious after the tourniquet is relaxed, the bleeding artery can be pressed by hand. If there is no bleeding, the tourniquet should not be used any more, but it should not be taken off immediately. It should be kept loose and continue to observe. It can be removed after hemostasis is.
  6.停用:停用止血带时应缓慢松开,防止肢体血流突然增加,伤及毛细血管及影响全身血液重新分布,甚至血压下降,取下止血带后应轻抚伤肢,缓解冰冷,麻木等不适感觉。
