Dave, I'm highlighting it because I'm trying to find out where the issue with the therapy is and why my sleep is still terrible. Mv hasn't picked up in deep sleep even after moving to ASV.
The concern is sleep is still very bad and not refreshing.

OK I gotcha. It helps me to put things in perspective, thanks. Stick with us and with enough back and forth info, we'll do our best to help you. Just as a reminder, what's your current therapy settings?

Have you tried it with the ASV, solely with the goal of increasing TV in mind?
If not, might be worth giving it another go, say with the typical minimum of 6-inches of dead space. I imagine you'll know pretty quickly if it'll work or not in terms of the hyperventilation.

RE: Should I switch to Bi-PAP and is it worth it for me?
I tried EERS with the ASV last night.
I woke up in the middle of the night feeling a bit suffocated and very tired. I switched back to normal and woke up feeling a bit better. After going back to normal mode MV dipped to lower levels.
MV was a bit higher than it normally is during deep sleep - 4.9-5.1
It seems I did not hyperventilate on EERS on the ASV.

Can you please describe your EERS setup?

FWIW, I found my median TV and MV increased by 20%.

My full face mask has 2 vents. One big one and one smaller one in the tubing adapter. I blocked the smaller one.
RE: Should I switch to Bi-PAP and is it worth it for me?
Well, that's a kludge, and I would not consider it EERS. Even with half the design vent-rate, the mask does not hold expired air because the mask vent rate is about four to five times respiration. The EERS system moves the vent to the end of an known volume of tubing and allows the design vent rate to occur there. You may have increased CO2, but we can't quantify it and I'm uncomfortable with that kind of modification. The controlled increase of CO2 can increase respiratory drive, moving up tidal volume, respiratory rate and minute vent. The physician that prescribes this also will prescribe Diamox to slightly acidify the blood to encourage respiration. It mostly seems to treat therapy onset central apnea, but it works to improve respiratory volume as well. I would not trust the effect of blocking half of the expiratory vent to achieve any kind of predictable result.
