Supplemental oxygen is a prescribed medical treatment for people whose health condition causes low blood oxygen levels. It should be used only under the guidance of a qualified clinician, with the prescribed equipment, flow rate, and follow-up plan.
Why Evaluation Matters
Breathlessness, fatigue, and low oxygen readings can have many causes. A clinician can determine whether oxygen is needed and whether additional testing or treatment is necessary. Oxygen should not be used as a general wellness treatment or a substitute for medical evaluation of respiratory or cardiac symptoms.
Home Oxygen Safety
MedlinePlus provides patient guidance on storing and using oxygen safely at home. Oxygen equipment creates fire-safety considerations, so patients should follow the prescribing team’s instructions and avoid smoking or open flames near oxygen.
