Aerobic Interval Training in Patients With Chronic Obstructive Pulmonary Disease (COPD) and Hypoxemia
Effects of Aerobic Interval Training on Cardiac Function, With Special Focus on Pulmonary Pressures and Right Sided Function, in Patients With Chronic Obstructive Pulmonary Disease and Hypoxemia
Patients with severe Chronic Obstructive Pulmonary Disease (COPD) and low oxygen levels in the blood are at risk of developing pulmonary hypertension and strain on the right side of the heart, both of which are known to increase symptoms and worsen prognosis It is not fully established whether interval exercise training in patients with severe COPD and concomitant low oxygen levels is beneficial.
This study aims to evaluate the effects of aerobic interval exercise training in patients with severe COPD and low oxygen levels in the blood, with a particular emphasis on such effects on the cardiovascular system and pulmonary circulation.
