I also use the 50 ft. of hose with my oxygen. When I change the hose I unwrap it and put it in the clothes dryer for maybe 5 min. just enough to get it warm. It will untangle and when you remove it from the dryer, just keep stretching it as you take it out. It helps to stop the tangling up and wraping around your legs. One of my PT's gave me the suggestion. It works, just don't put in there for 15 minutes or more!! Have a great day and breathe easy. God Bless.

I use #2 oxygen all night, really helps me sleep so very soundly...Mornings are rough when I wake because getting my body rid of congestion and used to breathing on my own is a mild feat. A cup of coffee helps, and just sitting doing those types of chores, like lists for activity during the day chores, and chores for others. Also grocery lists and appointments. By then I'm doing fine.
I'm suppose to use oxygen when doing chores, I do half the time...but too much of the time I want my independence from the oxygen and be normal...oh I huff and puff and breath too much out of my mouth...I just yearn to be normal...

I sleep with my oxygen on from time to time, my respiratory doctor says I need to be careful when I do, and I understand why, your body can tell when you have too much oxygen, I'll have dizzy spells and tightness of my chest. This has happen to me twice from sleeping with my oxygen on, so I'm careful about it. I've learned what doesn't work for me may work for you, and vise versa.

I do sleep with O2 at night which is what I began with. In addition to make it better to breath. Use two to three pillows so my head is elevated all night.

I used to have minor nose bleeds with my oxygen at night. Now I have a bottle of water that attaches to my compressor. Not a problem anymore.
