Curative Effects of Intermittent Noninvasive Ventilation on COPD Patients with Respiratory Failure

Objective To explore the clinical effect of intermittent noninvasive positive pressure ventilation(NPPV)in the treatment of chronic obstructive pulmonary disease(COPD)with respiratory failure and its complications.Methods Forty-two cases were randomly divided into two groups.Group A was treated with routine method and intermittent NPPV,whereas the group B was treated with routine method and continual NPPV.The arterial blood gas analysis(pH,PaO_2 and PaCO_2)and complications were recorded in 24 h and 72 h respectively.Results There was no statistical difference in effective rate,value of pH,PaO_2 and PaCO_2,rate of failure,days of hospitalization between the both groups(P0.05).The incidence of complications in group A was significant lower compare to group B(P0.01).Conclusions Intermittent NPPV with a lower rate of complications has similar effect as continual NPPV for COPD patients with respiratory failure.
