The effect of cardiopulmonary intensive interval training on cardiopulmonary oxygenation and exercise capacity of elderly patients with COPD during convalescence

目的研究心肺强化间歇训练对老年慢性阻塞性肺疾病(COPD)康复期患者心肺氧合能力和运动能力的影响。方法我院诊治的168例老年COPD患者,随机信封法分为常规组(83例)和强化组(85例),前者给予常规康复训练,后者在其基础上给予心肺强化间歇训练。比较两组干预前后心肺氧合能力、运动能力、血气指标和肺功能,评估患者生活质量。结果两组干预后心肺氧合能力各项指标水平均升高,且强化组高于常规组(P<0.05);两组干预后6 min步行实验(6MWT)、肺功能指标、各项生活质量指标水平均上升,COPD评估测试(CAT)评分下降,pH值、动脉血氧饱和度(SaO2)和氧分压(PaO2)水平均升高,二氧化碳分压(PaCO2)水平降低,且强化组上升或下降幅度大于常规组(P<0.05)。结论心肺强化间歇训练应用于老年COPD患者中,对于其心肺氧合能力、肺功能以及运动能力的提高均具有较好的促进作用,进而可改善患者血气指标和生活质量。

Objective To investigate the effect of cardiopulmonary intensive interval training on cardiopulmonary oxygenation and exercise capacity of elderly patients with chronic obstructive pulmonary disease(COPD)during convalescence.Methods Using the envelope method,168 elderly COPD patients diagnosed and treated in our hospital were randomly divided into routine group(n=83)and intensive group(n=85).The former received routine rehabilitation training,and on this basis,the latter received cardiopulmonary intensive interval training.Cardiopulmonary oxygenation,exercise capacity,blood gas indexes and lung function in the two groups before and after intervention were compared.The quality of life was also assessed.Results After intervention,cardiopulmonary oxygenation of the two groups was increased and the intensive group was better than the routine group(P<0.05).After intervention,the 6-min walking test(6MWT),pulmonary function indexes and quality of life indicators were all increased in both groups.However,the COPD assessment test(CAT)scores were decreased.Further,pH values,arterial oxygen saturation(SaO2)and partial pressure of oxygen(PaO2)were increased while partial pressure of carbon dioxide(PaCO2)was decreased.All increase or decrease in the intensive group was greater than that in the routine group(P<0.05).Conclusion Cardiopulmonary intensive interval training can promote the improvement of cardiopulmonary oxygenation,lung function and exercise capacity of elderly patients with COPD,thereby improving blood gas indicators and quality of life.
