Thanks for your suggestion, SassysMom. My machine does have the pre-heat feature. I'll try warm vs. cooler air!
Thanks very much Roy...I'll give all your suggestions a try!
After having two sleep tests performed in a Sleep Lab this past July, I was diagnosed with moderate sleep apnea, snoring and slight leg twitching. My sleep disorder physician recommended therapy with a C-PAP machine and a full face mask. I'm going on night #6 using the machine and I've noticed a slight improvement in feeling 'refreshed' on a couple mornings, but not nearly as refreshed as I felt the morning after I was on the C-PAP machine during test night #2. I used a full face mask then, as I do now. The air I was breathing on the lab C-PAP seemed cooler than the air coming from my machine - it's a Philips Respironics DreamStation with heated humidifier. I'm also experiencing severe dry mouth that wakes me up about every two hrs.. I didn't have the dry mouth problem with the test lab C-PAP. Communication with the respiratory therapist who set me up with the machine and fitted me with the full face mask I have now suggested increasing the humidifier setting and making sure I'm not having mask leaks. This particular machine has a feature that indicates a good mask fit with a :40 sec. test and I keep getting the green 'OK' checkmark for a good fit. I've tried turning the humidifier all the way up (and down), but haven't had success reducing the dry mouth problem. Anyone having similar experiences or suggestions to help eliminate the dry mouth syndrome would be appreciated.
