Influences of Respiratory Training on Pulmonary Function and Survival Quality of Sufferers of Chronic Obstructive Pulmonary Disease in Catabasis

Objective To study the influences of respiratory training on pulmonary function and survival quality of sufferers of chronic obstructive pulmonary disease(COPD) in catabasis.Methods Forty-six patients with COPD in catabasis(pulmonary function is from level 2 to level 4) were given respiratory training for 6 months individually or in group;then the differences of pulmonary function and survival quality were observed before and after training.Results Thirty-six patients completed the experiment.The forced vital capacity(P0.05),forced expiratory volume in a second,forced expiratory volume in a second/ forced vital capacity and flow velocity of respiratory peak value were markedly improved after respiratory training(P0.01).The mean scores of 4 survival quality factors were all decreased remarkably(P0.01).Conclusion Respiratory training can improve pulmonary function of COPD sufferers during catabasis and upgrade their survival quality.
