目的：研究浅快呼吸指数(RVR)即f/VT对机械通气患者撤机的指导意义。方法：对准备撤机的患者28[摘要]目的：研究浅快呼吸指数(RVR)即f/VT对机械通气患者撤机的指导意义。方法：对准备撤机的患者28例，监测常规撤机指标：每分通气量(VE)、阻力(Raw)、顺应性(Crs)、气道闭合压(P0.1)、内源性呼气末正压(PEEP)；呼吸频率(RR)、潮气量(VT)在自主呼吸试验开始时测定，观察其对撤机的指导意义。结果：20例撤机成功，8例撤机失败。两组浅快呼吸指数(f/VT)分别为(70.3±19.4)bpm/L和(91±25.9)bpm/L，撤机失败组明显高于成功组(P＜0.05)。在撤机成功组中，17例(f/VT≤100bpm/L)，3例(f/VT＞100 bpm/L)；在撤机失败组中，4例(f/VT≤100 bpm/L)，4例(f/VT＞100 bpm/L)，以f/VT≤100bpm/L为标准，预测撤机成功的诊断正确率、灵敏度和特异度分别为75％、85％和50％。结论：RVR对撤机有一定的指导意义。

Objective: To evaluate the rapid-shallow- breathing index (RVR) as a weaning parameter in mechanically ventilated patients. Methods: Standard weaning criteria: minute volume (VE)、 airways resistance(Raw)、 compliance(Crs)、 airway occlusion pressure(P0.1)、intrinsic PEEP(PEEPs) wear measured in 28 cases with mechanical ventilation. Respiratory rate (RR, bpm)and tidal volume(VT, ml)were measured at the beginning of a spontaneous breathing trial. Results: In sucessful group of 20 patients, rapid-shallow-breathing index(f/VT )was (70.3+19.4) bpm/L; in 8 patients with weaning failure, f/VT was(91+25.9) bpm/L, and was significantly higher than successful weaning group(P＜ 0.05) . Successful weaning, 17(f/VT≤100 bpm/L), 3(f/VT＞100 bpm/L) ;failed weaning, 4(f/VT≤100 bpm/L), 4(f/VT ＞100bpm/L). Using an f/VT≤100 bpm/L as the threshold value for predicting successful weaning,the diagnostic accuracy, sensitivity, specificity were 75% 、 85% and 50%.Conclusions:Rapid-shallow-breathing index(f/VT )was one of the better indexes for predicting weaning.
