I have just been out for lunch with hubby and 12 of our Breathe Easy group.
One of the ladies who is 4ft nothing lugs about this oxygen cylinder on her back, I asked if that was the smallest she could get and she said yes. She uses so much energy getting it on and off she is exhaused. I am not on oxygen myself but I understood you could have a much lighter concentrator can you get these supplied by your oxygen provider.
