The Effect of Mechanical Ventilation Therapy on Acute Left Heart Failure

Objective To evaluate the possibility and the clinic value of the sequential mechanical ventilation therapy on acute left heart failure.Methods Methods:80 patients with intermediate syndrome were included in the study.of them,50 were randomly allocated to receive sequential mechanical ventilation,and the other 30 received invasive positive pressure ventilation(IPPV).And ventilator-associated pneumonia(VAP),mechanical ventilation duration,the length of hospitalization,were measured.Results There were significant difierenees in invasive ventilation time,the total duration of mechanical ventilation,ventilator-associated pneumonia(VAP),the length of hospitalization between sequential treatment group and the control group(P0.05).Condusion invasive-noninvasive ventilation is effective treatment for acute left heart failure,it can significantly shorten the time of invasive ventilation,the length of hospitalization and reduce the incidence of VAP.
