Objective:To assess the clinical efficacy of the ventilator treatment of non-invasive mechanical ventilation in the elderly patients with chronic obstructive pulmonary disease(COPD) with respiratory failure.Methods:Collected 61 cases from elderly COPD patients with respiratory failure in our hospital

A total of 24 cases for using ventilator-non-invasive mechanical ventilation was the treatment group

A total of 37 cases for not use was the control group

The two groups were similar to medical treatment

Treatment group to the ventilator treatment of non-invasivemechanical ventilation.Results:The outcome of ventilator-non-invasive mechanical ventilation group

20 cases of good tolerance

Only two cases can not be tolerated.After the treatment arterial partial pressure of oxygen(PaO2) and carbon dioxide partial pressure(PaCO2) significantly improved than that before treatment(P<0.01);compared with the control group

It shortened the average length of stay in hospital(P<0.05) and the time of blood gas improving

blood pressure levels in patients with the treatment group had no significant effect(P>0.05);the ventilator-barotrauma or the ventilator-associated pneumonia did not occur.Conclusion:The nasal(facial) mask respirator non-invasive mechanical ventilation is a safety and effective method to treatment of the elderly COPD patients with respiratory failure.
