I have been using the Philips CPAP machine with a nose cradle successfully for 4 years. I was given a ResMed Air Sense 10 Autoset and had a parched mouth (as if someone had put a hair dryer in my mouth) and kept waking up every several hours. After 7 days, I switched back to my Philips. HAS ANYONE had this problem with the ResMed Air Sense 10?? Last night I used my Philips once again – I did NOT have a parched or dry mouth and slept well. I was using the same mask and headgear for both machines. I really want to like the ResMed Air Sense, as it has some great features and is easier for traveling. Any suggestions? I have had 3 calls with ResMed customer service, and the same number with my medical provider. The last ResMed suggested that my provider send the machine to them to be checked.
