Effects Oxygen Supplementation Determined Better Exercise Capacity in Eisenmenger Syndrome

Acute Effects of 40% Oxygen Supplementation Determined Better Exercise Capacity in Eisenmenger Syndrome

The purpose of this study was to evaluate the acute effects of oxygen supplementation during a submaximal exercise test in patients with Eisenmenger's Syndrome.

Patients with Eisenmenger's syndrome were submitted to a submaximal exercise test (six-minute walking test) with and without supplemental oxygen. The distance walked during the two tests were compared to assess the impact of oxygen supplementation on the walking distance.
