I've been trialling a F&P Icon Auto with the heated ThermoSmart Breathing Tube & a Lady Zest Q nasal mask, and have been having issues with rainout. Machine is on auto with pressure range of 7 to 20, machine is situated below sleeping head height, & hose wraps up & over headboard.
On the first night the Humidity level was set to 4 (the default setting) - horrible rainout work me in the early hours of the morning. There were droplets right thoughout the tubing.
I was surprised as I thought the heated tubing would largely prevent rainout. Also, I live in a sub-tropical clime so the evenings are not overly chilly, at the moment they're about 16oC (60oF). Anyway on the 2nd night I dialled the humidity back to 3, same problem with rainout occured. Last night I dropped back to a setting of 1 and finally slept through without rainout waking me out.
My only concern now is that come winter I am going to have to raise the humidity level & worry that this will cause massive rainout again. Any thoughts on this?
Initially I had thought to get a tube cosy but I've learnt from this very informative site that that's a no-no!
Might just be paranoia, but I'm surprised how warm the water chamber gets, even on such low settings. I came home early from work today & realised I hadn't emptied the chamber out (naughty I know), so removed it from the machine and you know what, it was warm to the touch! Could it be that this new machine has a faulty thermostat in it? Any suggestions welcome! Any F&P owners out there had any hassles like this?
Thanks folks, look forward to learning lots from everyone.
