FlexO2: A patient-controlled oxygen flow selector improving autonomy and daily function in long-term oxygen therapy (LTOT)

FlexO2 significantly improved the ease of oxygen dose adjustment and physical activity capacity, potentially enhancing patient autonomy in LTOT. While overall patient-reported quality-of-life scores improved, objective quality-of-life outcomes remained stable. Further studies are warranted to explore long-term clinical outcomes and the potential impact on caregiver burden.
