Clinical observation of mechanieal ventilation in treatment of acute left heart failure

Objective To evaluate curative effect of mechanical ventilation in treatment of acute left heart failure.Methods 37 patents of acute left ventricular failure carried out non-invasive or invasive mechanical ventilation.The changes of blood gas analysis,heart rate and blood pressure were observed.34 patents of acute left ventricular failure without mechanical ventilation were as the control group.The clinical data and fatality rate were analyzed.Results For patents in mechanical ventilation group,their heart rate and blood gas analysis were obviously improved before treatment.Compared with control group,fatality rate of patents in mechanical ventilation group was obviously reduced.Conclusion Mechanical ventilation can quickly and effectively cure acute left ventricular failure to reduce fatality rate.
