Newly Disgnosed ASV
#1
Newly Disgnosed ASV
What I was on CPAP for many years with pressure set at 15.  New study shows I have centrals so ASV was recommended.  I am using an Aircurve 10 ST with an F&P Evora FFM and this is my fourth day and really struggling.  I thought it would be an easier transitioning from my previous pressure setting.  I am constantly adjust the straps after the pressure ramps up.  I even pulled out my old nasal pillow hoping it would be better but both options had different problems.  With the FFM I can't control the leaks If it is a small leak the cool air on my skin is irritating enough I can't sleep and with big leaks it's a disaster.  The nasal pillow fits better but with the pressure is so high I get a gurgling noises in my mouth that are loud in my head so I can't sleep plus the pressure is harder on my nostrils.  Also one night it was pushing so much air it made my stomach hurt.

Here are my study finding so any comments or suggestions are welcome.

EPAP min 17 and max 21

Pressure Support max 8 they were unable to set the max that high so I am not understanding what  pressure support does. 

Max pressure 25

Breath rate 12

With both mask options I feel like I have a harder time exhaling.  

I've seen posts about OSCAR and wonder if that's something I should use since my machine only has a card with all the data on it.

We need to see your charts to help you. You said your pressure is going up, why it's going up will point us in a direction and your daily charts will guide us.

RE: Newly Disgnosed ASV
Lizziecats, the Aircurve 10 ST and the Aircurve 10 ASV are two different machines and serve completely different breathing disorders. If you have in-hand a prescription for ASV, you should call the supplier that mistakenly provided the ST and insist that ASV be dispensed as ordered by the doctor. The two machines are not interchangeable. Here is a link to the Resmed Clinical Titration Guide https://document.resmed.com/en-us/docume...er_eng.pdf Please read the conditions that ASV and ST are intended to treat and how each one works very differently.

Your ST is meant for people with pulmonary and neurological disorders that cause COPD, hypoventilation and other restrictive pulmonary disorders. The ASV is uniquely designed to treat complex and central sleep apnea. The ST provides fixed pressure and pressure support on each breath to enhance volume. It has a fixed backup rate to trigger IPAP if spontaneous breaths do not occur. The ASV works with much lower EPAP pressure and has adaptive pressure support that changes on a breath by breath basis to maintain your respiratory rate and volume with or without spontaneous breathing. You have the WRONG machine and should complain to both your doctor and supplier! Someone doesn't know what they are doing and you are being treated with settings and equipment appropriate for a COPD patient, not a central or complex apnea patient.

RE: Newly Disgnosed ASV
Thanks for responding. I went back to the owner's manual just to make sure i got the name correct.  It says AirCurve 10 ST-A sorry for leaving off the A so does that change your response in any way. I am also attaching my sleep study reports in case that might help as well. The first one was a BiLevel Titration and the second one was an ASV titration.

I have an appointment to see the respiratory therapist on Monday because of the issues I am having.  I guess we will look at a different mask but I still have concerns that I can only wear it between 2 and 3 hours before I have to take it off because I simply cant sleep.  Last night was a little better in controlling major leaks but only because the mask was so tight.  And I know the recommendation is always to not over tighten but so far that isnt working for me.  And that is why I went to a nasal mask 15 years ago when first on CPAP. 

I will be setting up OSCAR so in time the reports might provide some helpful info but not sure that works unless I actually asleep.

Thanks again for any wisdom you can share before I see the respiratory therapist.
