With the popularization of medical knowledge and the development of medical technology, people pay more and more attention to COPD. This paper mainly studies the effect of virtual reality technology combined with comprehensive lung rehabilitation on patients with stable chronic obstructive pulmonary disease. 60 patients with stable chronic obstructive pulmonary disease were selected to collect their general information, such as name, gender, and age. They were divided into the experimental group and control group, 30 patients in each group. The experimental group was treated with virtual reality technology combined with lung rehabilitation, while the control group was treated with conventional rehabilitation. Patients in both groups needed medication and participated in a 30-minute disease description activity once a week. In addition, patients in the control group should walk for 20 minutes every day to monitor muscle fatigue. Breathing exercises are also carried out regularly. Patients are instructed to use their lips and abdomen for 5 minutes each time. The respiratory rate was 7 beats per minute. In addition to the routine training of the control group, the experimental group will also train the simulated bicycle for 20 minutes, which will be automatically saved on the computer after the training. After the experiment, the muscle function and motor ability of the two groups were evaluated, and the results were statistically analyzed. The total self-efficacy scores of patients before and after telemedicine technical support increased significantly (2.15 ± 0.21 before telemedicine technical support, 2.39 ± 0.20 after telemedicine technical support), and the difference was statistically significant ( P < 0.05 ). The results show that the application of virtual reality technology can improve the rehabilitation belief of patients and strengthen the training effect.

A large number of clinical studies have shown that mechanical ventilation is an important means to improve the airway ventilation and oxygenation status of patients. In this paper, the meta-analysis method was used to analyze the effect of inspiratory muscle training on respiratory muscle function in ICU mechanically ventilated patients. By computer searching PubMed, Embase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wan-Fang Data, VIP Chinese Periodical Database (VIP), China Biomedical Literature Database (CBM), From the library to April 2021, the relevant literature on inspiratory muscle training on inspiratory muscle function in ICU mechanically ventilated patients was analyzed. Stata14.0 software was used for Meta-analysis, and the results showed that inspiratory muscle training was helpful to improve patients' MIP (MD = −1.17, 95%CI−8.7, −0.47, P < 0.05); reduce patients' mechanical ventilation time [MD = −0.74, 95%CI (−1.42, −0.06), P < 0.05]; reduce the length of hospital stay [MD = −1.87, 95%CI (−3.22, −0.11), P < 0.05]. The study shows that IMT can improve MIT and reduce the length of hospital stay and mechanical ventilation.
