Abstract:
Objective To explore the effects of lung rehabilitation using Spiro-tiger training apparatus on the respiratory mechanics and airway remodeling in patients with chronic obstructive pulmonary disease(COPD)in stable stage.Methods Ninety-three stable COPD patients admitted to Nanxiang Branch of Shanghai Ruijin Hospital were randomly divided into control group(46 cases)and observation group(47 cases).Control group was treated with the training for pursed lips breathing and abdominal breathing,and observation group was trained with Spiro-tiger training apparatus in addition to the treatment given to control group.Both groups were intervened continuously for 9 weeks.The two groups were compared in terms of respiratory mechanics(respiratory frequency,tidal volume,minute ventilation,and peak respiratory pressure),airway remodeling[matrix metalloproteinase-9(MMP-9),vascular endothelial growth factor(VEGF),and transforming growth factor-β1(TGF-β1)],and lung function[forced vital capacity(FVC),forced expiratory volume in the first second(FEV1),and FEV1/FVC],blood gas analysis indexes[arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2)],6-minute walking distance(6MWD)and health status[Borg scale and St.George's respiratory questionnaire(SGRQ)].The patients were followed up for 6 months,and the incidence of acute exacerbation of COPD was recorded.Results After 9 weeks of intervention,compared with control group,observation group had lower peak respiratory frequency and respiratory pressure,and higher tidal volume(P<0.05).There was no significant difference in minute ventilation between two groups(P>0.05).The levels of MMP-9,VEGF,TGF-β1 and PaCO2 were lower,and FVC,FEV1,FEV1/FVC and PaO2 were higher in observation group than in control group(P<0.05).Observation group had longer 6MWD,and lower Borg score and SGRQ score as compared with control group(P<0.05).After 6-month follow-up,the incidence of COPD acute exacerbation in observation group was lower than that in control group(4.26%vs19.57%,P<0.05).Conclusion Lung rehabilitation using Spiro-tiger training apparatus can effectively improve respiratory mechanics,lung function,blood gas analysis indexes and health status in stable COPD patients,alleviate airway remodeling,and avoid acute exacerbation of COPD.
