Introducing myself. I am currently using a resmed Air Sensor 10 machine, with pillow mask. I have adjusted to the pillows very well. I did not have a single problem adjusting to using this machine or wearing the mask. I have been using it for aprox. 7 months. The first couple of months I saw a very good change in myself I was only have on average 1.6 - 3. events per hour using it ( 30 events per hour prior to the machine.) Now all of a sudden I am waking every hour on the hour (no leaks in the mask) my events have increased to just over 6 per hour. (which I assume is averaged) Since I wake very hour it takes me at least 30 mins. to return to sleep, only to awaken in an hour. Which was exactly why I went to the doctor in the first place. I wore home tester. The air flow is set on 6 to adjust up to 12. I called the air tech. She was to send a report to the doctor. I have yet to hear from him. I am wondering if I increase this airflow to 8 if this could possibly help. Also is it necessary for proper sleep to run the humidifier?
