Abstract

Background: Passive chest mobilization leads to a change in the muscle length of the thoracic wall and may result in increased lung compliance in prolonged mechanical ventilation patients.


Objective: To investigate the effect of passive chest mobilization on dynamic lung compliance and spontaneous breathing time during weaning in prolonged mechanical ventilation patients.


Methods: Twenty prolonged mechanical ventilation patients were randomly divided into two groups. Ten patients in the intervention group (mean age: 62.90 ± 29.43 years) received passive chest mobilization 30 times per set, 3 sets per day, for 5 days combined with conventional chest physical therapy (deep breathing exercise, percussion vibration postural drainage and suction). Ten patients in the control group (mean age 65.30 ± 21.33 years) received only conventional chest physical therapy. Comparison of the differences in dynamic lung compliance and spontaneous breathing time before- and after-training within and between groups.  


Results: Five days after the program, the intervention group found significant improvement in mean dynamic lung compliance. Before and after training, it was 26.29 ±11.29 ml/cmH2O, and after training it was 35.07± 13.09 ml/cmH2O (p<0.05). The mean of spontaneous breathing time during the weaning period showed significant improvement after the program, it was 6.41 ± 7.6 hours to 16.18 ± 9.11 hours, and the significance was different when compared with the control group (p<0.05).


Conclusion: Passive chest mobilization combined with a physiotherapy program could improve dynamic lung compliance and spontaneous breathing time in prolonged mechanical ventilator patients. Further studies should be conducted on a large population.
