如果动脉以脉动性唧筒(pulsatile pump)搏动灌注一个35厘米水银柱高的脉动，我们会记录到动脉的脉动性变化。

If the artery were perfused from a pulsatile pump with a 35 mm Hg pulse, we would record a pulsatile change in arterial volume.

如果肢体血流灌注良好但是两边脉搏搏动是不对称的或者abi、US检查不正常，那就需要请血管外科医生会诊，同时行动脉造影检查。

If the limb is still well perfused but the pulses are asymmetric or ABI is abnormal or us is abnormal then consult vascular surgery and obtain arteriogram.
