Hi denimday, and thanks for this post and question - it's a good one! You are definitely not alone as others in the community have expressed similar concerns when it comes to managing the supply tubing used to provide oxygen therapy.
I thought you might gain some additional insight from this article, published right here on COPD.net, which focuses on this very issue: https://copd.net/living/tangled-oxygen-line. I do hope you find the information is helpful for you in a practical way.
Wishing you well,
