Long term oxygen therapy—it is still relevant?
Long term oxygen therapy (LTOT) at home is almost the standard of care for domiciliary management of chronic obstructive pulmonary disease (COPD) with severe hypoxemia. LTOT is widely practiced all over the world for several other chronic conditions, with or without hypoxemia. It is not only a costly mode of therapy, but also poses several logistic and psychosocial issues for the patient as well as the care-givers. “Whether the LTOT prescription is medically useful and indicated” is the core question which every physician needs to answer before prescribing this treatment.
