A109 HIGHLIGHTS IN PULMONARY REHABILITATION: ILD, ADJUNCTS, AND INSPIRATORY MUSCLE TRAINING: Automatically Adjusted Oxygen Flow Rates (freeo2) Optimizes Oxygenation And Improves Walking Distance During Exercise In Hypercapnic O2-Dependent Chronic Obstructive Pulmonary Disease (COPD)

Rationale: Unadjusted O2 flow rates explain frequent O2 desaturation occurring during exercise in COPD on long-term oxygen therapy (LTOT), which may reduce the exercise tolerance in this population. SpO2, pulse rate, respiratory rate and oxygen flow were continuously recorded during the two conditions with the same sensors embedded in the FreeO2 (set in closed-loop mode during the FreeO2 condition and in recording mode during the constant O2 flow condition).
