The bi-pap machine has a "gadget" connected to the output flow with a swivel on it. I connect the oxygen tubing to the swivel on the gadget and the bi-pap hose to the other end. In essence the bi-pap ...a spacer with oxygen swivel ...mask hose. I don't know any other way to connect the oxygen.
WELCOME! to the forum.!
Hang in there for more answers to your questions.
I also think you should get another opinion. My family member doesn't need his bipap at all if he has oxygen fed by canula. Seems to me her overall quality of life is superior with oxygen only.
Okay BiLevel and COPD here, no O2.
I had headaches and was told that I was retaining CO2. I did not have to change the therapy pressures to "fix" this
I use a Resmed machine, so I can only talk about my personal machine.
I was mainly hypopnea with a few OA and more centrals, the machine removed all the hypopneas and 90% of the OA.
now for the breathing and comfort stuff.
again I don't know what these things are called on your wife's machine or what features are available, I am guessing that there is something similar.
On Resmed there is a inhale time setting and a trigger level. There is a chart on how to set these for COPD users. BUT for me that was the exact opposite of what I needed.
There is a bar on the screen that shows pressure during my breathing, starts at min and goes to max and then drops back quickly. I could sit there and watch the bar progress and it would drop off BEFORE I had stopped inhaling. On the Resmed this is the TiMax setting, what is the maximum time the machine will let you inhale. Default was 2.0 seconds. I changed it to 3.0 seconds and it "seemed" fine. Then After no improvement overnight I looked at sleephead and noticed that my breathing slowed down overnight. adjusted to 3.4 and it was much better. Recently I changed to 3.7 seconds and am oh so much better. I also changed my trigger to high sensitivity to make sure it caught even slight inhales.
COPD and sleep apnea are two different things and both need to be treated. I do not suggest that your wife stops using CPAP because of her COPD and quality of life. Tune up the therapy so she can treat both. My DME and Sleep Doctor were of zero help in doing this. Doctor finally said that I had his permission to change any and all setting on my own, he had given up.
Don't give up, test different settings and my guess is that as long as the apneas are behaving, then you don't need to change therapy settings to get things sorted out.
Oh and running more O2 into the mask does not make your wife inhale it or help her to expel the CO2.
Keep posting with progress.

Permit me to rephrase that. TiMax is the maximum time the machine will stay at IPAP pressure; not the maximum time it will let you inhale. The machine may switch from IPAP to EPAP pressure; but you may still be inhaling.
Now, let me add a caution to changing default timing parameters -- these parameters are best left at default. Anyone who wants to tweak them needs to fully understand what these parameters do; and that they do so at their own risk.
What worked for PoolQ is not a solution for everyone with COPD.
