Abstract

Respiratory Muscle Endurance Training (RMET) by means of tube-breathing‚ an easy and inexpensive method of normocapnic hyperpnoe‚ improves exercise performance‚ dyspnea‚ and quality of life in patients with COPD (Koppers‚ Chest 2006 in press). The mechanisms explaining these beneficial effects are unknown‚ but a decrease in hyperinflation on the long term might be hypothesized. The acute effects of tube-breathing on dynamic hyperinflation haven‘t been investigated untill now. It could be speculated that hyperpnoe during tube-breathing leads to progressive dynamic hyperinflation.
To investigate acute changes in lung volume due to tube-breathing we included 15 patients with COPD GOLD II-III‚ residual volume (RV) >150%pred (60 % male‚ mean age 65.8 ± 8.3 yrs). Tube-breathing was performed according to a validated protocol (Koppers‚ Respir Med 2005). After instruction and a learning period of 7 days a 10-minute tube-breathing test was performed. RV was measured before and after the test using bodyplethysmografy. Inspiratory capacity (IC) and dyspnoe (Borg scale) were measured before‚ during and after the test. Data were analysed by paired t-tests.
Tube-breathing did not effect RV: mean (SD) 177.2 (34.5) %pred to 176.3 (36.1) %pred (p=0.7). In addition‚ no significant changes in IC were observed. Dyspnea increased significantly during tube-breathing (Borg 2.3 (1.3) to 3.1 (1.6) (p= 0.002)).
The results of this study show that 1 session of tube-breathing does not induce acute dynamic hyperinflation and leads to only a mild increase in dyspnea sensation and is therefore applicable in COPD. It has to be investigated whether the beneficial effects of RMET might be due to a decrease in hyperinflation on the long term.
