I would not make too much of one night of results. Now that you can sleep, give it a little while for your body to get used to it. At least a week. Then see what is going on.

I am not a Medical professional and I don't play one on the internet.

RE: Problem with Autosense 10 central apnea detection
Hey guys can you explain something to me, when you look at 06:00:25, I get an OA for about 20 secs. A that time I am only at a pressure of 8 out of a maximum of 12 but even though I am far from my maximum pressure, the machine has no reaction whatsoever, stays at 8 and does not raise its pressure. Is this normal? What good would it do for me to raise the max and try to clear the OAs if the machine doesn't get to the max?

That's an isolated OA that occurs with no detectable associated flow limitation or snoring. The machine is programed to only increase the pressure if two or more events occur within a minute or two of each other OR if the event is also associated with flow limitations or snoring.

RE: Problem with Autosense 10 central apnea detection
Hi Johnthesleeper
I just got the resmed airsense 10 autoset as well, I was custom to using an older CPAP that did not have all the new features and my pressure setting was raised to 14 recently as well which is high
I was using the mirage fx nasal Mask as well and did get some of the same affects you are experiencing. After talking to the Resp Therapist she suggested to move from a nasal Mask and go to a full mask that covered the nose and mouth to help with that issue. Hope this helps. I will be using the full mask tonight. .....Good sleeping

RE: Problem with Autosense 10 central apnea detection
Oh I thought flow limitation was represented by a flat flow rate? What technically does flow limitation mean then?

Ressler: I also have a mirage fx and a quattro. Come to think of it, the enhanced FOT arousals also only happened on the mirage fx; when I use the quattro, I do not feel the FOT even without a ramp. So I think richc was right and there must be some sort of breathing reaction that only occurs with the nasal mask and that amplifies the FOT...

A flat line on the flow rate graph that lasts for 10 seconds or more is an apnea. If it's shorter than 10 seconds, it represents a short pause in breathing.

A flow limitation is a change in the shape of the inhalation parts of the flow rate graph that are indicative of increasing respiratory effort due to subtle changes in the airway. They are thought to be indications that the airway is at higher risk of collapsing or partially collapsing and hence APAPs are programmed to increase the pressure when flow limitations are detected.

Sometimes it's easy to spot the flow limited inhalations---they're flatter on top or they have a distinct "chair shape" that is different from the usual round inhalation shape. Sometimes the changes are so subtle that it's hard to see why the breaths are earmarked as "flow limited".

flow limitation is explained, along with other aspects of SDB, in this video:
