Abstract:
Objective To investigate the application value of breathing machine noninvasive positive pressure ventilation in acute myocardial infarction patients with left ventricular failure.Methods 70 acute myocardial infarction patients with left ventricular failure were randomly divided into observation group and control group,the control group received conventional treatment,on the basis of the control group,patients in the observation group were treated with noninvasive positive pressure ventilation.The treatment indicators and the proportion of converted to endotracheal intubation,mortality and length of hospital stay were compared between the two groups.Results Compared with the control group,the PaCO2,RR,HR and SBP of observation group reduced more significantly,PaO2 and SaO2 increased more significantly(t =4.2588,5.144,7.127,4.2814,6.4719,6.2629,all P ＜ 0.05).Compared with the control group,the SV and EF of observation group increased more significantly,CVP decreased more significantly (t =12.0527,14.0937,14.6425,all P ＜0.05).The patients converted to endotracheal intubation and mortality ratio were significantly lower than the control group,the average length of stay was significantly shorter than the control group(x2 =4.6289,4.2000,t =6.3892,all P ＜ 0.05).Conclusion In the treatment of acute myocardial infarction patients with left ventricular failure,noninvasive positive pressure ventilation can significantly improve cardiac function,lung ventilation and ventilatory function,increase the therapeutic effect.
