Nobody seems to know why but I've ended up in hospital on 15l/min. They have finished iv antibiotics and are going to reduce my oxygen level and see what happens. Then i can go home to hospital bed, commode etc.
I don't think home concentrators can flow that much but a dr said maybe i could use two, one up my nose maybe on 4l/min and as much as i can through a mask. It that feasible? My blood pressure and oxygen are good just in bed, but if i do anything dramatic like get out of bed to use the commode, they drop like a stone. Oromorph works very well and very quickly, maybe that's the answer?
