RE: Waking with palpitations
Don't you love it?
I have had a nuclear stress test and cardiac ultrasound exam and they found no problems!

I still have occasional atrial fibrilations though.. I know that is what it is because I watched the event on a
EKG montior in the ER once.

So then the doc comes in and runs a printout AFTER it's over and goes. "Mmhmm. You're fine no problem here."
So I was "Well, yah you DUMB***! you missed it!"

Anyway, sometimes your heart will trip over something in the dark, only thing I can conlude at this point.

Hi SleepRunner, welcome to the forum!

Good to hear you are having a fairly easy time adapting to
PAP treatment, other than the occasional bad central.

Central events which occur occasionally during the beginning months of PAP therapy will sometimes (I think will usually) slowly disappear as our system becomes acclimated to PAP treatment.

Did you ever wake up with palpitations before starting PAP therapy? (I did, very often, and with PAP treatment that does not happen any more.)

Those of us who are susceptible to central apneas often have problems if we try to use EPR (Exhalation Pressure Relief), because with some people using EPR can cause central apneas. Most people do better when using EPR or Flex or whatever, but a few of us do worse with EPR and have the best sleep quality when EPR is turned down to 1 or turned completely off.

Lastly, if I remember correctly, I think one member reported a few months months ago that he suspects he has fewer central apneas when he eats a little coconut oil with/after dinner. He got kidded a little by other forum members, but it makes sense to me that it could help, because the medium chain length oils tend to be easily but slowly digested and could provide support for more constant blood sugar levels throughout the night. I bought some at Costco and have been meaning to start using it on food instead of butter, and let folks know if I feel any improvement. (Would have to go by how I feel because I can't go by my AHI; with the ASV machine, my AHI is pretty much always zero except for a rare obstructive event perhaps once every few days.)

Take care,
--- Vaughn

If the machine never raised above 8cmH2O, it sounds to me like the minimum pressure might be set higher than it needs to be.

You mentioned a feeling of hyperventilation - that feeling usually comes from problems dealing with pressure. After one gets used to high pressure the low pressure can feel suffocating - suffocation and hyperventilation are two very different feelings.

Central Apneas can, at times (usually early on in PAP therapy), be a sign of trouble adjusting to pressure.

All of these other things aside though, the pressure never raising from the minimum pressure of 8cmH2O seems to me to suggest the minimum is too high.

If it were me, I wouldn't mess with the max pressure setting (the machine won't go any higher than it needs to any way); but, I might drop that minimum pressure down to 4cmH2O and see what happens.

Before doing that though, I would fake snore with the mask on to make sure the auto is working properly and the machine isn't broken - if it is working, then snoring should make the pressure go up.
