Central Apneas
I have an AHI average for the last 12 months of 2.4. This is mainly made up of centrals. I only have about 1 obstructive about ever 2 weeks and about 2 to 4 hypopneas every night. Some of my centrals I know are of the junk variety upon going to sleep and upon awakening. However alot of my centrals are like the type shown on my attachment. Are these real centrals or are they just arousels caused by rolling over or from leg movements ? Perhaps someone can enlighten me on this subject.[attachment=2705]

RE: Central Apneas
There's a difference between arousals (waking up) and centrals (not breathing). From the single shot you offer, this looks like not breathing. Unless you normally hold your breath for 15plus seconds whenever you jerk a leg or roll over, then it is a central event.

But the good news is there's not much to be worried about. The CI is below 5.

What I suggest is looking at your 95% and maximum reached pressure over several weeks span. If it is typical of the night in your attachment, you may want to lower your maximum treatment pressure. For example, you have it set to 6 to 15. For the night shown, you didn't reach 12. If that is your norm, I would suggest lowering the maximum to, say, 13 and let it run for a few weeks. It is highly possible the CAs decrease in count.

Thanks PaulaO2 for your advice. I will set the max pressure to 13 and see what happens.

RE: Central Apneas
Paula has some good advice for you. Your machine could be causing some hyperventilation which in turn which in turn causes the Centrals. Lower pressure could be helpful.

RE: Central Apneas
Don't set it to 13 unless your data shows you rarely if ever reach 12 or 12.5. If you need to go higher but the machine is set too low, then your OA events will increase.

RE: Central Apneas
PaulaO2, I checked my data for the past year and found that for the first half of the year my maximum pressure was in the 12 to 13 range most of the time. It even hit 15 on one occasion . However after I changed my pressure support from 3 to 2 my maximum pressure for the last 3 months was 11.3 and my 95% was 10.3. I guess my higher pressure support must have had something to do with the higher IPAP for the first part of the year.
What do you think,should I go ahead and try 13 IPAP ?
