（1)使用气囊止血带从充气后开始计算时间，一般为1小时，最多不超过1. 5小时放松1次，隔5~10分钟后再充气继续使用。(2) 使用止血带应掌握好充气的压力，一般成人上肢为40kPa，下肢为53~ 80kPa;小儿上肢为20~27kPa，下肢为27~33kPa。不得过松或过紧，过松则压力 只能阻断静脉血流，而不能阻断动脉血流,造成肢体充血，起不到止血的作用，反而 造成大量出血;过紧则有碍于肢体的血液循环，可导致组织坏死和神经损伤。(3) 恶性肿瘤或肢体有感染的情况下，只需抬高患肢，不宜使用驱血带驱血， 以免将细菌或癌细胞挤人血液,扩散至全身。(4) 气囊止血带的压力表用后要保持清洁，放干燥处，不得剧烈震动。 (1) the use of airbag tourniquet to start the calculation of the time after inflation, generally 1 hours, at most not more than 1.5 hours to relax 1 times, after 5~10 minutes after the continued use of air. (2) Use tourniquet should master the inflatable pressure, generally adult upper limb 40 kPa, lower limb 53-80 kPa; children upper limb 20-27 kPa, lower limb 27-33 kPa. Not too loose or too tight, too loose, the pressure can only block the venous blood flow, but can not block the blood flow, cause hyperemia of the limbs, can not play the role of hemostasis, but cause a large number of bleeding; too tight is hinders the circulation of blood in the limbs, which can lead to tissue necrosis and nerve injury. (3) in the case of malignant tumor or limb infection, it is only necessary to raise the affected limb, and should not be used to drive blood with the drive blood zone, so as not to squeeze the bacteria or cancer cells into the blood and spread to the whole body. (4) the pressure gauge of airbag tourniquet should be kept clean after being used.
