Randomized trial investigates arterial oxygen levels during exercise in COPD patients, indicating varying degrees of exertional hypoxemia.

This research aims to compare arterial oxygenation during exercise in COPD patients with and without exertional hypoxemia.
Examined arterial oxygenation at rest and during maximal treadmill exercise in a group of 17 COPD patients.
Compared patients with exertional hypoxemia to those without, assessing mixed venous PO2 and cardiac output.
Analyzed venous admixture and its correlation with arterial saturation at rest and during exercise.
Subgroup 1 with exertional hypoxemia had more severe respiratory impairment than subgroup 2.
Both subgroups exhibited similar desaturation of mixed venous blood during maximal exercise.
Subgroup 2 demonstrated decreased venous admixture during exercise, correlating with higher arterial saturation (r = 0.985).
