Abstrakt

Dyspnea on exertion is the leading symptom in patients with COPD leading to chronic disability. A lot of studies confirmed an improvement of exercise endurance and/or intensity and a relief of dyspnea by oxygen (O₂). Simple aim of our study was exploring the effect of O₂ (2 l/min) on daily living activities (bending, working overhead). In a single-blind trial 40 patients with COPD bended and worked overhead in a randomized manner for one minute each with room air or with O₂. The number of actions carried out per minute was noted. Both activities led to a significant drop in oxygen saturation (SaO₂) without or with O₂. Average SaO₂ per activity time significantly raised when O₂ was applied. This, however, was neither followed by a rise of actions per minute nor by a reduction of dyspnea measured by BORG scale. O₂ supplementation in this flow rate for this time and for these activities is, thus, not advantageous.
