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,PP,Pm,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(P0.05).Conclusion:In patients with respiratory failure type Ⅱ,MRV results in lower PIP,PP,Pm as compared with CMV,PEEPi with MRV mode was significantly lower than these with CMV.
