Abstract

【Objective】To evaluate the effect of non-invasive bi-level positive ventilation(BiPAP) in patients with pulmonary encephalopathy due to chronic obstructive pulmonary diseases(COPD).【Methods】A study was conducted in 30 patients with pulmonary encephalopathy due to chronic respiratory failure.Each patient was added noninvasive positive pressure ventilation(NPPV) based on conventional management.Aterial blood gas(AGTB) analysis,HR,RR,PetCO_2 were detected immediately before and at the end of each ventilation.【Results】The parameters were set as the S/T mode,IPAP(16±2)cm H_2O,EPAP(8±3)cmH_2O,FiO_2 30%~40%.Of 30 patients,28 patients showed improvements in symptoms and gas exchange.The changes were significantly marked,2 cases were intubated due to failure of BiPAP ventilation,no patients died.【Conclusion】BiPAP ventilation is an effective way in treating pulmonary encephalopathy due to chronic obstructive pulmonary disease.
