[|Human|] Good Evening Sir or Ms., My friend has a M.D. order for home O2 due to Emphysema. He wants to wait until his C.T. results are in. By what He has told me he has a Tracheal issue as well-hence the CT. { apparently his Trachea is abnormal in shape. ] I say get the O2 now,use it as prescribed to see how effective it is in relieving his S.O.B. Your thoughts please,I thank you
[|AI|]  Oxygen is prescribed when someone's oxygen levels are below a certain number. Assuming that this was the reason he was prescribed oxygen, he should start using it immediately. The CT will not determine whether he needs oxygen, although you may help explain why he needs it. The oxygen by itself may not necessarily make him feel better, but it is one of the few interventions that will protect his body and allow him to live longer.
