the effects of pulmonary physical therapy on the patients with respiratory failure

Background: we aimed to investigate the application effects of pulmonary physical therapy on the patients with respiratory failure. methods: overall, 132 patients with respiratory failure admitted into the affiliated hospital of medical collage of ningbo university from 2013-2017 were enrolled and divided into control group (n=66) and observation group (n=66). patients in the two groups received conventional physical therapy but those in observation group received pulmonary physical therapy additionally. the ventilation and air-exchanging functions, scores of acute physiology and chronic health evaluation ii (apache ii) and occurrence of complications in patients in the two groups were compared. results: pao2, paco2, pao2/fio2 and estimated fev2% were greatly improved in patients in the two groups after treatment and those in patients in observation group were better than those in patients in control group; the differences were statistically significant (p=0.014). there were no statistically significant differences in the scores of apache ii in patients in the two groups before treatment and at 2 days and 3 days after treatment. scores of apache ii of patients in observation group were obviously lower than those of other group at 4 days and 7 days after treatment and the differences were statistically significant (p=0.015, 0.029). the total incidence rates of complications in patients in observation group and control group were 7.57% and 39.39%, respectively, and the difference was statistically significant (p=0.021). conclusion: the treatment of respiratory failure patients with pulmonary physical therapy can greatly improve the ventilation and air-exchanging functions, avoid the occurrence of complications and improve the health condition.
