概要 | BACKGROUND:Although it is useful for COPD patients to relieve their dyspnea by bracing their arms, the relationships between the arm bracing posture and expiratory flow limitation (EFL) and lung volume are unknown. Whether arm bracing affeBACKGROUND:cts dyspnea, EFL, and lung volume in elderly COPD patients was investigated.METHODS:Sixteen elderly subjects (median [interquartile rangeMETHODS:]METHODS:age 81 [77-85METHODS:]METHODS:y) with stable COPD (percent-of-predicted FEV1 50.9 [31.3-64.9METHODS:]METHODS:%) and 16 age-matched healthy subjects were studied. Breathing patterns, EFL, lung volume, SpO2 , and heart rate during quiet breathing were randomly evaluated in 3 standing postures: erect, leaning forward, and arm bracing. Dyspnea was also assessed for each posture with a Borg dyspnea score at the end of the test.RESULTS:Lung volume was significantly higher with arm bracing than with the other postures in both groups (PRESULTS:<RESULTS:.05). Breathing patterns, SpO2 , and pulse rate were not significantly different among the 3 postures in both groups. However, EFL and Borg dyspnea scores were significantly lower with arm bracing than with the other postures in COPD subjects (PRESULTS:<RESULTS:.01).CONCLUSIONS:The decreased EFL in the arm bracing position may be caused by breathing at a higher lung volume than in the erect position, which may be one of the factors relieving dyspnea in elderly COPD patients. |
