Carefully fill in the nursing records of the use, including the location of the tourniquet, the tension of the tourniquet, the time to stop the bleeding, and the completion of the skin and tissue before and after the buckle. 4.每次使用前预先检查气卡扣止血带、插扣、隼头相闭合，弹性带是否完好（合为一体的除外），插扣、隼头是否匹配、牢靠。 Before each use, check the gas card buckle, the buckle, the falcons head, the elastic band is intact (except for one), the buckle and the falcons are matched and secure. 5.止血带拉力大小根据患者年龄、血管收缩压、止血带的宽度、肢体的大小而决定。就健康成人而言，上肢拉力：患者血压的收缩压加50~75mmHg；下肢压力：收缩压加100~150mmHg（国际手术室护士协会建议）。止血带拉力压脉过大或不足均可能造成神经伤害，不足的压力可能产生肢体静脉充血而造成神经的出血浸润。 5. The tensile strength of the tourniquet is determined by the age of the patient, the systolic blood pressure, the width of the tourniquet, and the size of the limb. For healthy adults, upper limb pull: systolic pressure of patients with blood pressure of 50 ~ 75mmHg; Lower limb pressure: systolic pressure plus 100 ~ 150mmHg (recommended by the international operating room nurses association).
