I have to admit that lately my time has been limited and I have not had time to spend specifically on this. I realize that the machine may use snoring and/or flow limitation to determine that an apnea is coming, but, I thought that the pressure increase wouldn't occur unless an apnea actually happened, not before. I do sleep on my back, not by choice, but necessity.

From the Resmed site: A ResMed device with AutoSet delivers only the pressure you need when you need it. It senses your pressure needs by monitoring your airflow. Certain patterns of airflow indicate the coming of an upper airway obstruction, which will cause an apnea, hypopnea, or snoring... Responds effectively - automatically increases the pressure if it detects flow limitation, snore, or apnea – giving you three lines of defence.

So it's a pretty smart machine - it can (sometimes) anticipate an apnea and prevent it before it happens.

Thanks Paul! Guess I should have been thinking b/c I had it somewhat wrong

According to an article I found a week or so ago, there are "responding events" and "predictive events". The machines respond after the fact to an actual apnea. They change pressure proactively in the event of flow limitations and/or snoring.
