Objective: investigate the clinical characteristics of chronicobstructive lung disease complicated with pulmonary interstitialfibrosis. Method: Choose these 240 patients with chronicobstructive lung disease who were diagnosed and treated in thehospital from 2014 to 2016, and 80 patients were checked withchronic obstructive lung disease complicated with pulmonaryinterstitial fibrosis; these patients were underwent with CTexamination, lung function examination and blood gasexamination. Result: through the CT examination, it indicates thatthe patients with c chronic obstructive lung disease withpulmonary interstitial fibrosis show excessive lung permeabilityand bullae of lung, etc. It has the statistical difference comparedwith these patients with chronic obstructive lung disease (P <0.05). The difference of lung function and blood gas indicatorbetween the two groups is statistically significant, which is ofstatistical significance (P<0.05). Conclusion: The clinicalcharacteristics of chronic obstructive lung disease complicatedwith pulmonary interstitial fibrosis are excessive lung permeabilityand bullae of lung, and the lung function and blood gas indicator ofthese patients are significantly different from those patients'indicator with chronic obstructive pulmonary disease, so it can beregarded as an important way to diagnose patients.
Effect of negative pressure ventilation on arterial blood gas pressures and inspiratory muscle strength during an exacerbation of chronic obstructive lung disease.
