Hi katw - I am glad to hear you are trying to get back to your 'norm' following a 3-week illness. I am sorry to hear this happened to you. However, it is commendable that, now that you're feeling better, you are returning to your exercising.
It's understandable that the lengthy oxygen supply tubing might be getting in the way as you walk around using the rollator. If you have sufficient lengths of tubing, you may want to try to drape the tubing up, and off the floor, so you can mobilize with the rollator more freely.
Do you think this may be of help?
I am also hopeful, others will see your post and weigh in with their own experiences and suggestions.
Please do check back and let us know how you're doing with the exercising.
Good luck!
