I see where some say oxygen is a medication because it requires a physician's order. Well so does PT, OT, ST, glucometers and much more. But when it comes to management, if oxygen is used in a hospital it it managed by a respiratory tech, not a nurse. In a home setting, there is not nurse to assess them all day, so anyone on oxygen would therefore require a nursing home setting. It can be turned on at a specific setting and evaluated regularly by a physician, but used daily without nursing assessment or management in a individuals home. It is ordered and paid for by insurance under durable medical equipment, not pharmacy. Just saying.
