Weird question - please help!

As well as what has been suggested. There are a couple of things you can do.
wait till you get use to it, it will happen and your brain blocks it out.
You can move to a machine that doesn't check for CA. So there will be no pulse.
I would raise your min pressure to 8 and max pressure to 14 and then review. I think it will help with your AHI

sigh- Ive been waking up at 3 am every morning...why???! Ughhhhh

Your graph shows you were awake from 3 to 5. Did you try sleeping from 3 to 5? The graph shows the unit was not on from 3 to 5.

exactly. I woke up...couldnt sleep so I took it off to read for awhile.....then put it back on and tried again

Did you always managed to sleep through the night even without a break? If so you can expect things to change! Scientist have, for a long time, wondered how the brain rids itself of toxins. Studies have shown that the brain drains the toxins through the blood when you are asleep (it has no lymphatic system). The better the sleep the more the drain. That likely is why many people need a bio-brake! Your graph shows increase in pressure long before you wake up. The unit is trying to keep you asleep.

I have the predecessor to the machine that you have. I don't think much has changed between the machines from what I heard. There was a period of time when I experienced what you were talking about. At the time I described it as a blast of air. It would startle me when I was drifting off.

I can't say what was causing the problem exactly, but at the time I was using ramp and had a low pressure setting like yourself. I think it also started when I switched from cpap to apap mode. Thus allowing the machine to adjust pressure as it needed. That's when it started to blast me with air.

If your set to apap mode the machine should adjust pressure as needed. If you happen to be using ramp which starts at a low pressure and you stop breathing the machine will override the low ramp pressure and increase the pressure as needed. This may seem pretty significant and startling. It was for me at the time. The forum members advised against using the ramp feature so the machine will start at a higher pressure. Then the pressure changes won't seem so significant. It takes a little while to get used to a higher pressure, but after a while you don't even notice.

Another thing that helped in my case is raising the overall pressure, which I would only do if it's needed. My pressure it now set at 10-14. With the constant higher pressure I don't notice the changes anymore. It's nothing like it was when it was set in the 5-10 range.

Another thing to consider is that many of us stop breathing when we are still awake. This often happens right before we drift off. The machine will take action and increase the pressure. It doesn't know if we are asleep or awake. All it knows is that we stopped breathing and starts pumping more air.

All that said, you still may have a malfunctioning machine. Getting the machine data posted here so the members can look at it would help tremendously.

I was able to click on your link for one night of data. I can see the machine is going through quite a few pressure changes and that you use the ramp feature. I'm far from an expert, but to me it looks like increasing the minimum pressure a little would be the way to go and to practice going without the ramp feature. Those are the same things that helped me also. There are others on the forum that can give way better advise than myself. Get a few graphs up from several nights for people to look at and you should get the help you need.

An APAP can't increase the pressure when you stop breathing.

I think you should increase your minimum pressure so that it will change less.

The "blast" of air is not a change in pressure, its literally just that, a short, quick POOF of air and then it goes back to what it was doing. Its like someone blowing an air canister into your nose

Pressure pulses....little puffs of air that the machine uses to help it figure out if the reduction in air flow is central in nature or obstructive in nature.
Get the provider manual from here (request via email) and read up on it.

Most people don't notice them because they are so small but some people seem to be ultra sensitive to them and they can then become real annoying.
There is no way to stop them. Why they are happening when you are awake enough to notice them is probably because you are breathing a bit irregularly (we all do it when awake) and the machine is trying to anticipate a need to decide if something is happening or not.
They don't always end up being followed by an apnea event flag of some sort.

If you can't put them out of your mind well enough to sleep through them then maybe you should talk with your provider about a change in machines to something that is less annoying with how it distinguishes centrals from obstructives. They all use something though.

It just seems odd to me that it didnt seem to be happening for the last few months but just started doing it very recently. I confess last night I went to sleep without my machine and didnt put it on till about 4:00 am to 6:30 am. I am honest to god more rested today than I have been in weeks....What the heck??

Your machine is set to auto so it changes pressure for various reasons. Puffs happen at 4 Hz during some apneas to determine if it is CA or not. If you are breathing regularly there should be no puffs. Unless your machine is malfunctioning, which there is no reason to suspect, it is doing what it always does.
Regardless, I suggest you raise your minimum so that pressure changes are less which may help you enjoy better sleep. Good luck.

UPDATE----------

4 nights ago I took all the moving parts off. Put everything back together and now it doesnt do it anymore. I knew it wasn't "normal". Im hoping this change sticks!

I'm glad things have resolved. BTW, what are the "moving parts" that you took off?

I've been having pressure pulses too. I never noticed them, but I know that they're happening per SleepyHead.
