Tourniquets, which every Boy Scout learned how to make back in the day, are now a first-aid no-no.

过去的童子军都知道怎么制作的止血带，对现在的急救来说是个禁忌。

与以往的“止血带”模型不同，采用手术制备股静脉以利于控制性再灌注及预防静脉阻塞。

Sterile pneumatic tourniquets are available for operations about the elbow, and the limb may be prepared and draped before the tourniquet is applied.

肘部周围的手术可使用无菌气囊止血带，在应用前肢体可先进行皮肤消毒、铺单。

约10分钟的空中飞行，他们专注于拯救伤员，保持心跳，给伤员输氧，使用止血带止血。
