I think that would be a great place to start.
Let me tell you a little story about me and maybe it will put your mind at ease about using straight bilevel vs APAP.
I used APAP for 2 1/2 years. My settings were 10 minimum and 20 maximum. My long term overall average was just under 12 cm..my long term 90% pressure was around 13. There were times (usually couple times a week) that my APAP would go up to 16 to 18 cm and I couldn't blame it on leaks. When I started using the BiPap at straight bilevel pressures of EPAP 9 and IPAP 13....I was a bit concerned about those times that happen when I used to see 18 cm. I worried about possibly seeing some events increase because I didn't have a higher IPAP. You know what? I don't see them like I thought I would. I still have some ranges with my AHI anywhere from 0.5 to a little over 4.0. I had the same thing on the APAP. If my IPAP of 13 is letting some events sneak past the defenses...I sure don't see it on my reports. If they are happening, they certainly are not occurring in any great numbers.
Short of using 20 cm straight pressure all night we can't expect to completely eradicate all events and even then I am not so sure we can. Obviously no one wants to use 20 cm all the time. We want to use the lowest pressure that we can which will give us good consistent results AND still be comfortable and sleep well with. So sometimes we compromise just a little.
If your dad rarely goes above 13 cm now..there is no reason to think that the pressure would need to be above 13 on the BiPaP except for a very rare circumstance and sometimes those happen no matter what the pressure.
Obviously if you could find a BiPap Auto somewhere then you would have the best of both worlds.
I have a BiPap Auto. I did use it in Auto mode. My results were pretty much identical to what I see in straight Bilevel mode. Auto mode wasn't any huge "improvement" because straight bilevel did a great job anyway. I just like the way straight bilevel feels while I am awake and since there is no huge change with auto mode..I elected to use what is most comfortable while awake.
Give the BiPap a trial. See how your dad feels about it. He might like the APAP better, you never know.
It sounds like he will do pretty well with either. Let him try the other to see if it feels better in general. I think on paper...both machines will more than take care of the events. Just see if one machine "feels" better to him.
