I have an oxygen concentrator downstairs which I use on 4 litres a minute when walking around and 2 litres a minute when resting. I need 2 litres a minute when sleeping at night. My tubing reaches from downstairs to my bed. Does anyone have a good idea on how I can go upstairs with the concentrator on 4 litres a minute so that I can walk around upstairs and do my active cycle of breathing (huffing) to cough up my mucus, but then turn it down to 2 litres a minute while I sleep. I do not think there is any solution but someone may be in the same situation.
I think I have to turn it down to 2 litres a minute before I go upstairs and take my oxygen cylinder upstairs with me and use the cylinder on 4 litres a minute.
