May enhance exercise metabolism in hypoxemic COPD; leaves open outcome benefits and practice change pending larger RCTs.
Does 30% O2 breathing improve O2 uptake kinetics and reduce O2 deficit during moderate exercise in male patients with COPD?
Supplemental 30% oxygen accelerates exercise VO2 kinetics and reduces O2 deficit in mildly hypoxemic COPD patients, suggesting enhanced aerobic metabolism in skeletal muscles.
Palange et al. (1995) studied this question.
