The American Thoracic Society has issued guidelines for the 6-minute walk test (6MWT). The 6MWT is safer, easier to administer, better tolerated, and better reflects activities of daily living than other walk tests (such as the shuttle walk test). The primary measurement is 6-min walk distance (6MWD), but during the 6MWT data can also be collected about the patient's blood oxygen saturation and perception of dyspnea during exertion. When conducting the 6MWT do not walk with the patient and do not assist the patient in carrying or pulling his or her supplemental oxygen. The patient should walk alone, not with other patients. Do not use a treadmill on which the patient adjusts the speed and/or the slope. Do not use an oval or circular track. Use standardized phrases while speaking to the patient, because your encouragement and enthusiasm can make a difference of up to 30% in the 6MWD. Count the laps with a lap counter. If the 6MWD is low, thoroughly search for the cause(s) of the impairment. Better 6MWD reference equations will be published in the future, so be sure you are using the best available reference equations.
美国胸科学会发布了6分钟步行试验（6MWT）的指南。与其他步行试验（如穿梭步行试验）相比，6MWT更安全、更易于实施、耐受性更好，且能更好地反映日常生活活动。主要测量指标是6分钟步行距离（6MWD），但在6MWT过程中，还可以收集患者的血氧饱和度以及运动时呼吸困难的感受等数据。进行6MWT时，不要与患者一起行走，也不要协助患者携带或拉拽其补充氧气设备。患者应独自行走，不要与其他患者一起。不要使用患者可自行调节速度和/或坡度的跑步机。不要使用椭圆形或圆形跑道。与患者交谈时使用标准化用语，因为你的鼓励和热情可能会使6MWD提高多达30%。用圈数计数器计算圈数。如果6MWD较低，要彻底查找受损原因。未来将会发布更好的6MWD参考方程，所以要确保你使用的是现有的最佳参考方程。
