AbstractNoninvasive intermittent positive pressure ventilation (NIPPV) via nasal mask became a routine method of treatment of severe exacerbations of chronic respiratory failure. The aim of the study was to apply NIPPV in patients with COPD admitted to hospital due to exacerbation of the disease who on standard treatment developed progressing respiratory acidosis (pH < 7.30). Fourteen COPD patients were treated with NIPPV. Arterial blood gases at the beginning of treatment were: PaO2 41 +/- 9 mmHg, PaCO2 = 87 +/- 17 mmHg, pH = 7.30 +/- 0.05. In 10 patients NIPPV applied quasi continuously resulted in clinical improvement and an amelioration of arterial blood gases. PaO2 rose from 41 +/- 9 mmHg to 56 +/- 12 mmHg, PaCO2 fell from 85 +/- 17 to 57 +/- 9 mmHg and pH rose from 7.30 +/- 0.05 to 7.41 +/- 0.04. In 4 patients NIPPV did not prevent further progression of respiratory acidosis. They were intubated and mechanically ventilated. Three patients survived and were discharged home. One patient died from septic shock. We conclude that NIPPV is an effective method to treat respiratory acidosis developing during exacerbation of severe COPD.
