Second of all let me give you some history. I am 67 and was diagnosed with Sleep Apnea about 20 years ago. I have used CPAP on and off since that time. I was never able to tolerate a full face mask so I have always used pillows. My return to CPAP was precipitated in May after discovering that I had severe blood pressure spikes at night. At that time I was trying to manage my apnea with a dental appliance. My sleep doc said that if I was spiking badly at night the dental appliance was not cutting it and directed my return to CPAP
That return was relatively smooth and I worked my way up to between 7 and 8 hours of sleep on CPAP. However over the past several weeks I have been waking up after about 2 to 3 hours labouring to both breathe and exhale. I think that my nasal passages are swelling. As a result I am forced to stop CPAP and use the dental appliance. If I wake up again after say an hour or two, I am able to go back to the CPAP and usually finish the night. I cannot figure out what has happened. I have my humidity set to the max as well as my hose heating. My EPR is set to 3.
If anyone has any experience with this and can offer some advice I would be grateful.
