Objective To observe the effect of early intervention and intermittent application of bi level positive airway pressure ventilation (BiPAP) in patients with pneumoconiosis combined with chronic respiratory failure.Methods Will meet the diagnostic criteria of pneumoconiosis in GBZ70-2009＜ ＞,the blood gas analysis in patients with chronic type II respiratory failure in 62 cases were randomly divided into rehabilitation treatment group 32 cases,control group of 30 cases.Patients in the observation group were treated by on-invasive ventilation,while the control group were treated by the conventional treatment.The data such as arterial blood gas、pulmonary function、the grade about dyspnea and echocardiography was collected from the both group before the beginning of the treatment and after the three months.Results the PaO2 level、FEV1.0、FEV1.0％ 、the grade of dyspnea and the Right Ventricular Ejection Fractions were not significantly different between the experimental group and the control before the start of the treatment (P＞0.05).After the three month treatment,the PaO2 level of the observation was significantly lower the control (P＜0.05).The data about FEV1.0、FEV10％ and the Right Ventricular Ejection Fractions were higher than the control group (P＜0.05).Conclusion Non-invasive ventilation has exactly effect in the treatment of the pneumoconiosis patients with Chronic Respiratory Failure.It can improve the function of the heart and lung and ease the pain of patients.
