[Pressure] Need Help with OSCAR Data

[marksmith5092]

Hi Everyone, 

I am new to the CPAP world.  I have a RESMED 10, I have not done well with nasal mask as I have too much mouth leaking.  So I am using a Siesta Full Face mask for now.  I had an AHI of 34 with my at home sleep test.  Never done in lab.  I am 34m athletic build 6' 225 lbs.   

Since I've started my treatments, I've never really seen AHI go above 1 when I was using the nasal pillows.  Those did not work due to mouth leakage no matter the tape or the amount of jaw wrapping I did.   

Since I consistently used the Siesta full face, I have been experiencing aerophagia and when I told my provider, they turned on ERP to 3.  The 3 was so much of a change I had problems falling asleep - so I changed ERP to a 1.  That worked and my aerophagia went away, but since then I've been having issues with my oxygen 4% desaturation events and the amount of time I spend below 94% oxygen (about 20-30% of the night).  I track my oxygen with EMAY SleepO2.  

Since then, I've tried to use a AirFit F30i and I cannot get enough air, so I went and upped the pressure in my clinical settings. I noticed that the upped air pressure helped a lot with the airflow of my F30i but ultimately the mask didn't work for how my nose is so I went back to Siesta.   When I left the upped the pressure, I had a great night sleep with my Siesta Full Face and my oxygen issues, after my provider turned on ERP, has gone away mostly (I just have 1 night of data on this).  That was just from me going from min pressure 6 to min pressure 7.  I also felt way better and rested when I woke up in the morning after I upped my min pressure. 

I was talking with one of the advisors from apneaboard and he took a glance at my data and suggested I should set my APAP to more of a CPAP and up my pressure to 10 and see how that works.  I like the idea, because when looking at my data, my APAP is adjusting between 9.0 and 10.0cm when dealing with my Obstructive Apnea events.  So the idea is to look for flow limitations when leaving at a closer range like 10-10cm for both min and max?

Can someone else take a look at my OSCAR data and give other suggestions? Attached is a data set from the other day (before I made the min pressure changes to try and fiddle with the F30i mask).

I suggest that you stick with Apap and set for 8-13.  That will leave you a little leeway to see what you actually need.

On your Oscar chart, please remove the calendar.  That will let us see more important things below.  Also, narrow the side panel.  You want it just wide enough to show everything.

Good luck with your new pap journey!

I'm an advocate for fix pressure treatment for OSA patients so I would second the advice for cpap @ 10cm or 11cm for now, apap tends to cause more arousals and micro arousals. I'd try it for a night or two and see how you feel then post a new chart.

I went to 8-13cm last night.  I set EPR to 1 (it was at 3) and I had a lot of dreams where I was burping.  I was experiencing Aerophagia again, so I woke up in the middle of night and set EPR back to 3.  

My oxygen went back to having a lot of time under 93%, not sure why when the night before min pressure was set at 7 and my oxygen was great! Would EPR fiddling cause this?


Attached is the new chart and O2 data.

Here is 10 setting last night, EPR 3.  Had a OSA event at 4am that woke me up and I couldn't get back to sleep.

Just a passing thought, but have you tried changing to the "Soft" Response setting? This may smooth the change between the EPAP to IPAP.

Thank you! I'll try that to see if its more comfortable!
