Use of Niv (BiPAP) Versus Facemask in COPD Patients Admitted to Emergency Ward with Type ii Respiratory Failure - A Prospective Randomized Controlled Study
COPD is a chronic disease of airway and lung parenchyma which is characterized by deficient airflow through lungs and incorporates chronic bronchitis and emphysema. Acute exacerbations cause Type II respiratory failure which is characterized by hypoxia and hypercarbia. Present study compares the efficacy of ventilation through face mask and BiPAP to treat type II respiratory failure. Exclusion criteria were age more than 90yrs, pH< 6.9, and pO2 less than 30mmHg.Chi square test for qualitative data and Student t test for quantitative data. P value less than 0.05 is considered statistically significant.
