ASV Quiestion

I have a ResMed VPAP Adapt SV, my mask is a Mirage Quattro FFM. My question is, The bridge on my nose is getting raw, I know how to change the settings on my machine, but will a nasal pillow work with a ASV for a short time. Untill my nose heals some. I prefer to use a FFM, its provides better therapy in my case, my pressure is kinda of high, the constant pressure is 10cm h2o with my average pressure at 11.8. I know its confusing but I'm new at this ASV machine. I will posting my readings as soon as I download them I have the software and hardware needed for this, just short on time.

Sure will!

My EPAP is 6; my MinIPAP is 10 and my MaxIPAP is 14 -- my IPAP runs around 11-12.

Both the Headrest and the Comfortlite 2 work very well with my ASV.

Consider a hybrid mask-- either the Innomed Hybrid or the Liberty. They do not rest at all on your nose bridge. They also work good at high pressure-- I am using mine (Hybrid) at 13-18 right now. Very comfortable to boot!

Kiralynx has a Bipap AutoSV & they are a different beast when it comes to masks.

The only way to be sure is to check Resmed's web site & if you do have a nasal mask, try the 'learning circuit test' on it and see if it accepts it. If it does, it might work, but, I will believe it when I hear it

Here is what Resmed say ... (for all their vpap models & masks ) ...

http://www.resmed.com/us/assets/documen ... er_eng.pdf

Go to the 3rd chart of the 3 in the doc. Basically it says N/V (Not Validaded). But run the learning circuit & see if it will accept it.

I want to thank you all for your inputs, I will try to adjust my mask and a bandaid with some neosporine. I hope this will work, if not I will have to rough it until I get better.

circuit will not validate with the nasal pillows attached.

Thank you for that answer. I suspected that the length of hose associated with the nasal pillows might cause problems, since this machine senses the pressure at the mask via the pressure sensor line that connects at the mask via the proximal cuff. It makes sense the length of tube beyond that point would cause it to not validate the circuit. Thank you for your insight and experience!

When we first started using the ASV in the sleep lab, we were not allowed to use nasal masks, due to this machine making adjustments off of leak, pressure needed, etc. This was the only machine we had that was very sensitive to mask leaks. We actually hated titrating with this machine as we were always in the room, fixing mask leaks so the alarm would shut off. So I assume the machine will not accept a nasal due to any possible mouth breathing, or air just escaping through the mouth. This is a great machine though! I also have FFM Mirage Quatro and I know exactly what you mean about the sore nose!!!

Yes,

I just keep politely saying, repeatedly, the Vpap Adapt SV is leak intolerant <= forced grin

It is an excellent ASV for cases where tight resipiratory control is a neccesity (the Bipap Auto SV does NOT deliver tight respiratoty control). Such cases include people with heart issues & some other ung complications. That proximal pressure sensor line allows the Vpap Adapt SV to 'spin-on-a-dime' in correcting respiratory difficulties occuring at one's face but not everyone needs such control

But, as many of us begin to realise over time - we have to usually 'suck-it-and-see' before we really understand how to describe a particular flavour to others. <= non-forced grin

Rather than leak intolerant, I might say that the fact it can swing wildly between one breath and the next tends to cause ANY mask on the market to leak. My Quattro full face mask is tightened down more than when I used it with my Respironics BiPAP M Series unit. I fail to breathe and it cranks the pressure around 23cm H20. Yikes! At that pressure, if I adjusted my mask to be just "floating" on my face without any pressure, it would be "floating" about six inches above my face at full pressure!

In fact, due to those strong swings, I am thinking about increasing the EEP from the default of 5. The swing from very low pressure to very high pressure seems to just cause the mask to leak more frequently.

"spin-on-a-dime" is a great way to explain it. The Respironics BiPAP Auto SV unit felt as if it plays more of a "follow the leader" game. It would lag behind. But the ResMed VPAP Adapt SV unit appears to change fairly quickly. It seems to take the lead role when I fail to breathe (or at least breathe deeply enough).

As to the type of conditions. It is pretty clear that I no longer have a normal respiratory pattern. Fortunately, no heart issues at this point. Just brain stem issues that leads to a lack of normal control of my respiration.

It's interesting seeing the data from my unit. I see long stretches where the pressure swings wildly. I assume the unit is struggling to maintain the correct volume. Then rather suddenly my breathing seems stabilize and the inhalation to exhalation pressure is much lower. That is, on the VPAP Adapt SV unit, the support it provides switches from EEP+MAX_PS to EEP+MIN_PS. And of course, with the lower difference between the inhalation and exhalation pressures, the mask leaks much less.
