选择长短宽度适合的止血带。应尽可能挑选宽的止血带，因宽的止血带和皮肤接触的面积增大，可以较小的压力提供止血效果，因其对止血带及边缘的神经所造成的压力较小，故而减少对神经和软组织的伤害，如：淤伤、起水疱、拧伤和皮肤坏死。

Choose a tourniquet with the right length and width. Wide tourniquet should be selected as much as possible. Because the area of wide tourniquet and skin contact increases, it can provide hemostasis effect with less pressure. Because the pressure on tourniquet and peripheral nerve is less, it can reduce the damage to nerve and soft tissue, such as: bruising, blistering, twisting and skin necrosis.
