Abstract: ObjectiveTo explore the influence of breath muscles functional training on convalescent patients with chronic obstructive pulmonary disease(COPD).Methods56 COPD patients had breath muscles functional training for 1 year and clinical indexes,including cold time,time in hospital,hemoglobin,blood gas analysis and hemorheology were observed.ResultsAfter breath muscles functional training,the cold time and time in hospital had shortened;hemoglobin,blood gas analysis and hemorheology of patients had ameliorated obviously(P<0.01).ConclusionBreath muscles functional training has affirmatively effect of boosting up corporeity,ameliorating lack of oxygen,adjusting internal environment on convalescent patients with COPD.

Key words: chronic obstructive pulmonary disease(COPD), breath muscles, functional training
