摘　　要：外周灌注指数(PPI)通过局部搏动血流与非搏动血流之比反映末梢微循环情况,是一个客观可靠的外周微循环指标。PPI在早期识别低血压、指导容量管理、评估血管张力、协助机械通气设置、早期识别术后并发症及判断危重患者不良预后等方面具有广泛的应用。Peripheral perfusion index(PPI)is an objective and reliable parameter reflecting the peripheral microcirculation through the ratio of local pulsatile to non-pulsatile blood flow.PPI is widely used in the early identification of hypotension,guiding volume management,assessing vascular tone,assisting mechanical ventilation settings,early identification of postoperative complications and poor prognosis of critically ill patients.
