目的探讨以呼吸引导动画为主体的慢性阻塞性肺疾病(COPD)稳定期患者呼吸肌网络训练系统对于改善患者肺功能、活动耐受力和生活质量的作用。方法 60例COPD稳定期患者参加了四阶段网络训练,对其1 s用力呼气容积/用力肺活量(FEV1/FVC)、FVC、最大呼气流量(PEF)、6 min步行试验(6-MWT)、试验前后登上10级和20级台阶前后心率和呼吸频率、与健康相关的生活质量进行了观察。结果患者试验前后的肺功能、运动耐力和健康相关的生活质量评分间差异有统计学意义(P<0.05),试验前FVC、FEV1/FVC、PEF等肺功能参数分别为〔(48.00±1.41)L、(52.89±0.75)%和(41.28±0.04)L/min〕,而试验后分别为〔(56.50±0.71)L、(63.79±1.11)%和(48.36±0.73)L/min〕,差异有统计学意义(P<0.05)。试验前6-MWT、登上10级台阶和20级台阶呼吸频率、登上10级台阶心率和20级台阶心率等运动耐力的测量结果分别为〔(298.00±59.43)m、(40.23±12.23)次/min、(46.22±13.25)次/min、(89.90±0.39)次/min和(100.33±1.52)次/min〕,而试验后分别为〔(360.02±66.50)m、(30.74±10.36)次/min、(34.27±14.05)次/min、(85.74±1.09)次/min和(90.67±2.08)次/min〕,差异均有统计学意义(P<0.05)。试验前圣乔治呼吸问卷(SGRQ)总分、呼吸症状、活动能力和疾病影响得分依次为(52.74±0.01)、(62.23±3.15)、(51.00±1.41)、(45.00±2.83)分,试验后则为(35.68±0.45)、(42.00±1.41)、(36.00±0.00)、(28.00±1.41)分,差异均有统计学意义(P<0.05)。结论 COPD稳定期患者呼吸肌网络训练系统可为患者呼吸肌的康复提供有效途径。
Objective To explore the effect of respiratory respiratory network training system on improving pulmonary function, activity tolerance and quality of life in patients with stable chronic obstructive pulmonary disease (COPD). Methods Sixty patients with stable COPD participated in the four-phase network training. Their FEV1 / FVC, FVC, PEF, 6-MWT, , Heart rate and respiratory rate before and after the boarded 10 and 20 steps before and after the test, and health-related quality of life were observed. Results The pulmonary function, exercise tolerance and health-related quality of life scores of patients before and after the experiment were significantly different (P <0.05). Before the test, the parameters of pulmonary function such as FVC, FEV1 / FVC and PEF were [(48.00 ± 1.41) L, (52.89 ± 0.75)% and (41.28 ± 0.04) L / min, respectively, and the values were 56.50 ± 0.71 and 63.79 ± 1.11 and 48.36 ± 0.73, respectively There was statistical significance (P <0.05). The results of exercise endurance such as 6-MWT, 10 steps and 20 steps respiratory rate, 10 steps heart rate and 20 steps heart rate were [(298.00 ± 59.43) m, (40.23 ± 12.23) (36.22 ± 13.25) times / min, (89.90 ± 0.39) times / min and (100.33 ± 1.52) times / min), while the values were (360.02 ± 66.50) m and (30.74 ± 10.36) (34.27 ± 14.05) times / min, (85.74 ± 1.09) times / min and (90.67 ± 2.08) times / min), the differences were statistically significant (P <0.05). The scores of SGRQ, respiratory symptoms, mobility and disease influence scores before the experiment were (52.74 ± 0.01), (62.23 ± 3.15), (51.00 ± 1.41) and (45.00 ± 2.83) (35.68 ± 0.45), (42.00 ± 1.41), (36.00 ± 0.00) and (28.00 ± 1.41), respectively. The differences were statistically significant (P <0.05). Conclusion Respiratory muscle network training system in patients with stable COPD can provide an effective way for the rehabilitation of respiratory muscles.
