I was on OFEV, albuterol, bretezi, trilogy (did nothiing for me), Travaso (but that is very expensive [app $30k a month] and hard to get the insurance that I had to cover it) , as well as. four other medications. Without oxygen I couldn't get my stats up to the 50s. However, I was on 5 liters of oxygen at the time and on that my O2 stats would drop to 39 when going to the bathroom or having my husband give me a shower (before transplant I could no longer give myself one) while on oxygen. I couldn't get my O2 stats to go up to 80 even. I would discuss with the pulmonologist, because like others have stated they are more experienced with the lung health and measures that can be used.
