摘要

目的:为了比较MRV对Ⅱ型呼吸衰竭患者呼吸力学影响及在Ⅱ型呼吸衰竭治疗中的意义。方法:19例Ⅱ型呼吸衰竭患者首先行CMV模式

然后行SIMV和MRV模式

每种模式均持续运行60min

分别观察气道吸气峰压（PIP）

气道平均压（Pm）、平台压（PP）、内源性呼气末正压（PEEPi）及血气变化情况。结果:MRV模式的PIP、PP、Pm明显低于CMV

差异有显著性（P<0.05）

MRV模式的PEEPi水平低于CMV

差异有显著性（P<0.05）

患者的同步性好。SIMV的PP、Pm低于CMV

差异有显著性（P<0.05）

但PIP及PEEPi水平与CMV比较无显著差异（P>0.05）。结论:MRV可降低Ⅱ型呼吸衰竭患者PIP、PP、Pm水平

MRV或可降低PEEPi

有利于撤机。

Abstract

Objective:To discuss the effects and clinical significance of MRV on respiratory mechanics in patients with respiratory failure.Methods:19 patients with respiratory failure type Ⅱwere firstly ventilated with CMV for 60 minutes

then MRV and SIMV mode were adapted .Tidal volume (VT) and minute ventilation(MV) in MRV mode was as the same as that in CMV and SIMV.PIP

PEEPi and arterial blood gas were recorded during above three modes of ventilation.Results:With MRV PIP

Pp and Pm were significantly lower than that with CMV(P<0.05);PEEPi with MRV mode was significantly lower (P<0.05) than that with CMV.With SIMV P_P and Pm were significantly lower than that with CMV (P<0.05)

but there are no statistically significant differences in PIP and PEEPi between SIMV and CMV(P>0.05).Conclusion:In patients with respiratory failure type Ⅱ

MRV results in lower PIP

Pm as compared with CMV

PEEPi with MRV mode was significantly lower than these with CMV.
