Observation of BIPAP therapeutic effect on chronic obstructive pulmonary disease with type II respiratory failure.

Objective To investigate the clinic effect of the facemask bilevel positive airway pressure (BIPAP) assisted ventilation on patients of chronic obstructive pulmonary disease (COPD)with typeⅡrespiratory failure . Methods The total of 50 patients were divided into two groups at random: treatment group (23 cases) and control group (27 cases). The routine therapy was only given in the control group, but BIPAP assisted ventilation and routine therapy both were given in the treatment group. The measures of heart rate, of respiratory rate and arterial gas analysis were observed before and after the treatment. Results The heart rate, respiratory rate and arterial gas analysis in the treatment group were improved significantly more than that in the control group (P0.05). Conclusion BIPAP assisted ventilation is certainly effective to COPD with typeⅡrespiratory failure.
