To evaluate the effects of a short-term pulmonary rehabilitation program on dyspnea, exercise capacity, and lung function, 15 patients with chronic respiratory failure due to pulmonary emphysema were enrolled in such a program for 3 weeks as inpatients. The program consisted of pursed lip breathing, diaphragmatic breathing, respiratory muscle stretch gymnastics, and walking with synchronized breathing. Dyspnea as measured with a visual analogue scale at the end of a 6-minute walk before and after the program (49.7 +/- 4.0% to 24.2 +/- 3.8%) decreased significantly (p < 0.01). As a measure of functional exercise capacity, the 6-minute walking distance (226.9 +/- 32.4 m to 292.1 +/- 35.8 m) increased significantly (p < 0.01). As an indicator of maximal exercise capacity, endurance time on an incremental treadmill test did not improve. Spirometric data did not change during the study. Total lung capacity (TLC) (8.44 +/- 0.70 L to 7.58 +/- 0.74 L) and residual volume (RV) (5.13 +/- 0.53 L to 4.28 +/- 0.59 L) decreased significantly (p < 0.01). The findings suggest that this program relieves dyspnea, increases functional exercise capacity, and decreases TLC and RV on patients with chronic respiratory failure due to pulmonary emphysema.
为评估短期肺康复计划对呼吸困难、运动能力和肺功能的影响，15例因肺气肿导致慢性呼吸衰竭的患者作为住院患者参加了为期3周的该计划。该计划包括缩唇呼吸、膈肌呼吸、呼吸肌伸展体操以及同步呼吸行走。在该计划前后，通过视觉模拟量表测量的6分钟步行结束时的呼吸困难程度（从49.7±4.0%降至24.2±3.8%）显著降低（p<0.01）。作为功能性运动能力的一项指标，6分钟步行距离（从226.9±32.4米增加到292.1±35.8米）显著增加（p<0.01）。作为最大运动能力的一项指标，递增式跑步机测试中的耐力时间没有改善。在研究期间，肺量计数据没有变化。肺总量（TLC）（从8.44±0.70升降至7.58±0.74升）和残气量（RV）（从5.13±0.53升降至4.28±0.59升）显著降低（p<0.01）。这些发现表明，该计划可缓解因肺气肿导致慢性呼吸衰竭患者的呼吸困难，提高功能性运动能力，并降低TLC和RV。
