In this study we try to observe the effects of comprehensive pulmonary rehabilitation therapy on pulmonary functions and blood gas indexes of patients with severe pneumonia during mechanical ventilation. A total of 120 patients with severe pneumonia were selected and divided into the experimental group (n=60) and the control group (n=60) through a random number table. Conventional therapy for severe pneumonia was applied to patients in both groups, and the experimental group was additionally treated with comprehensive pulmonary rehabilitation therapy, including warming-up exercise before training, respiratory function exercise, respiratory muscle training, health education, psychological support and nutritional intervention. The pulmonary function indexes, blood gas indexes, Borg index scores and 6-min walk distance (6MWD) of the two groups of patients were evaluated before treatment and at 6 months after treatment, respectively. In the control group, there were statistically significant differences only in forced expiratory volume in 1 sec (FEV1), ratio of FEV1 to forced vital capacity (FEV1/FVC), partial pressure of O2 (PaO2), arterial partial pressure of carbon dioxide (PaCO2), Borg index and 6MWD after treatment compared with those before treatment (P<0.05); as for intra-group comparisons, there were no significant improvements in other indexes compared with those before treatment, and the differences were not statistically significant (P>0.05). In the experimental group, all the indexes after treatment were statistically different from those before treatment and those after treatment in the control group (P<0.05); with regard to comparisons of the indexes between the control group and the experimental group, the differences were significant (P<0.05). Comprehensive pulmonary rehabilitation therapy is conducive to improving the pulmonary functions and blood gas indexes of patients with severe pneumonia during mechanical ventilation.
