Welcome Mhunter, can you add the model type of the Resmed S9 you are using in the machine profile, it is next to the power button on the CPAP. Are you using a heated hose? Is it coloured or clear? If it is you may need a cover or keep the hose under your blanket. If it is heated, you shouldn't get too much condensation.
What temperature do you have it set at? I live in Australia and have mine at set 22c or 23c.
WELCOME! to the forum.!
If you are using the standard (not the heated,) hose,)You could make a hose cover by taking some old socks, cutting the toes out of them and sewing them together to make a tube. Take either a velcro strap to hold it in place at each end of the hose or you could put a rubber band around the outside of the hose cover to hold it in place at each end. If you have the heated hose, you probably wouldn't need the hose cover. Hope this helps.
Hang in there for more suggestions and best of luck to you with your CPAP therapy.
