[Pressure] Pressure Issue?
#1
Pressure Issue?
Hey everyone, 
New APAP user here since last Saturday. As profile States I have an Airsense 10 Auto with the Humidifier set to Auto and Heated Tube. My prescribed range is 5-20. I have a Normal size F30i that fits securely. 

I put my SD card in the PC and used SleepHead or OSCAR (not saying which unless it's relevant, I know at least in the past this is a touchy subject). 

I noticed that my pressure seems to peak and stay between ~17-20 almost all night yet there are no leaks reported. It's not uncomfortable nor wakes me up but do find it odd that it is pinned in that range most of the night. 

AHI is typically in the 2's. 

Is there something I am missing here?

RE: Pressure Issue?
You should post a screen shot so people here can see the numbers and the graphs. Typically OSCAR is used. If you are running at higher pressures and can tolerate it, you are better off than most. Once you post your data, people here can advise on your pressure range. Obviously running a min of 5, is too low if you spend almost all your sleep in double digit pressures.

RE: Pressure Issue?
If the machine is set to auto-titrate you, it will migrate into a safe range of pressure values, minima and maxima, that result in the fewest numbers of events of any kind.  We should assume, if your AHI is typically near "2", that the machine is pretty much dialed in, although we might be able to nudge it, and you, into an AHI less than 1.5 with a bit of luck.

Your machine, if it has an SD card in the slot, will be able to upload your daily data into OSCAR.  Once we see your charts, properly organized per the OSCAR instructions, we might see where the machine is falling short, if it is fall short at all.

Thanks everyone. See attached.

(Ignore the leak before 11:30, the mask wasn't sitting right and I was playing around with it)

RE: Pressure Issue?
You should probably increase your minimum pressure closer to the median but first you should set EPR to 3cm full time. You have a lot of flow limitations which are probably driving the pressure up. EPR will reduce the flow limitations and should reduce the RERAs and hypopnea. It may also lower your median pressure. Please replace the mask pressure with the machine pressure graph. It is more helpful.

RERAS are not included in thr AHI but also disrupt sleep.

My sleep center is being of no help, trying to get my machine linked to them, so here we go with crowd-sourced advice (nothing wrong with that but am annoyed by how little help the sleep center is offering after the hundreds of dollars I've paid them). I will try setting the EPR and posting a new graph tomorrow. Thank you for your advice.

Edit:
After re-reading the above
Please do not mistake my frustration with a lack of gratitude or appreciation for this community or it's advice. Quite the contrary, without you I would be Dead in the water right now. Thank you everyone. I will post an update tomorrow.

I understand that your frustration is not with the forum. Based on many posts in the forum over several years it's clear that very few of us, including me, get much meaningful support from sleep canters or our doctors. You are not alone.

RE: Pressure Issue?
Your numbers are good enough that you always need to indicate how you feel.  When answering that question in a medical context you never want to provide the standard "I feel fine" answer.  The question that was being asked was "what are your symptoms, what should I be looking for?"

Your min pressure should never be lower than 4 + EPR so Min Pressure = 4 + EPR = 4 + 3 = 7.
This allows you to take full therapeutic value from your EPR.

How you feel is important because it plays into do you need a more advanced device that can provide more pressure support to better manage your flow limits and RERAs.
With your RERAs you should change your indicator from AHI to RDI.  RDI = AHI + RERAs
