ABSTRACT
Objective To evaluate the effectiveness and safety of BiPAP non-invasive ventilation on COPD patients during acute exacerbation(AECOPD).Methods 20 COPD patients were ventilated using BiPAP non-inva- sive ventilation through a nose or mouth-nose mask.Their vital signs(RR,HR and BP)and arterial blood gases indi- cators(pH,PaCO_2,PaO_2 and SaO_2)before and after ventilation were monitored and the clinical effectiveness was ob- served.Results The vital signs and arterial blood gases indicators of 17 of the 20 AECOPD patients were improved. PaCO_2 was lowered,pH,PaO_2 and SaO_2 were elevated,and the difference before and after ventilation was statistically significant(P＜0.05).Conclusion BiPAP non-invasive ventilation can improve the vital signs and physiological in- dicators of AECOPD patients,relieve their respiratory muscle fatigue and prevent them from exacerbation of respira- tory failure,thereby lower the need for endotracheal inrubation.
