and they may prescribe a heated hose. This will keep the hose warm and avoid the droplets of moisture from forming. If the condensation gets worse, the moisture can end up in your mask in a condition we call rain-out.

If this is a dry cough, then a dose of cough suppressant might help. Dextromethorphan (DM) is a simple cough suppressant. If you actually need to loosen phlegm then that would be an expectorant (guaifenesin). Keep it simple and minimal, don't get a multi-symptom remedy for a dry cough.

You can use a hose cover to help with the condensation until you get a heated hose(however long that is). You can use it with your heated hose also, if you like it.

Regarding dry cough, I would use Guaifenesin for that also - and would do it first, lots of times some extra membrane secretions will wash away whatever is irritating the membranes. I find Guaifenesin helps with bloody noses, dry cough, sinus headache, etc.
