Objective: To observe the Yiqi Huoxue Huatan expectorant noninvasive method with mechanical ventilation treatment of stage acute exacerbations of chronic obstructive pulmonary disease (AECOPD) the curative effect of respiratory failure. Method: Will conform to the criteria of 72 cases of fall off (including 20% of cases) AECOPD respiratory failure syndrome of lung and kidney phlegm and blood stasis resistance type lung patients were randomly assigned to two groups:control group treated with antibiotics

bronchial spasm

expectorant drugs and other conventional and noninvasive mechanical ventilation treatment

treatment group in the control group on the basis of taking the yuan tonga blood phlegm of traditional Chinese medicine

every day a dose

three times a day. Compared two groups of curative effect

with arterial blood gas (pH value

carbon dioxide pressure (PaCO2)

and oxygen partial pressure (PaO2) the improvement of the situation;Cough

chest tightness

and sound and other clinical symptoms and lung wet days in hospital. Result: Two groups

the treatment group (34 cases

19 cases were markedly effective

effective 12 cases

3 cases

the total effective rate of 91.18%;16 in 32 cases

11 cases were markedly effective

efficient

invalid in 5 cases

the total effective rate 84.38%. Two groups before and after treatment of the pH value has no obvious change

two groups after treatment carbon dioxide pressure (PaCO2)

and oxygen partial pressure index (PaO2) is a treatment before have significantly improved (P<0.05)

but the treatment group than the control group before and after treatment to improve the more obvious. Treatment group hospitalization days was significantly reduced (P<0.05). Conclusion: This study suggests Yiqi Huoxue Huatan method with phlegm AECOPD respiratory failure patients noninvasive mechanical ventilation treatment

can improve the clinical curative effect

improve blood gas index

shorten the patient in hospital days

reduce the economic burden in patients

give full play to the advantages of traditional Chinese medicine

and achieve complementary effect of Chinese and western medicine

improve AECOPD respiratory failure clinical curative effect of treatment.
