Back from having my blood gases and walk test done, outcome is to increase the oxygen to 3L from 2L when sitting and sleeping, to increase from 2L to 6L ambulatory/walking about. (Was having real trouble just getting from room to room) Hope this helps and I can get back to work soon, also tried saline through the nebuliser was ok with this so will try it for 2 weeks to see if it also helps my breathing!
Still waiting of a test to see if I can use a conserver BOC and the nurse organising this hopefully it will be soon as using 6L of liquid 02 won't last long! Val
