Trials: I've been able to fall asleep at 4/6 once for a couple hours one night, and at 4/7 for a total of 5 1/2 hours last night. (Biflex off, rise time 3) But it's been touch and go, because with this Resp. M Series it only gives me 2 or 2.5 secs for my inhale before it switches to exhale, long bef...

Ok, I bought and cleaned the $45 Resp. 700M bi-level. What settings should I try in the effort to not receive inhale pressure until I initiate inhaling (if that's what I need to avoid the suffocation response). Bi-flex off? Comfort rise set to what? Straight bi-level or auto bi-level? (Remember that...

The Respironics Bipap M Auto for $45 would give you an idea if bilevel settings would help or not. If you need help with it...I am familiar with the M series machines and can help. Only problem with the M series is the default PS of 2 in auto mode...and for that reason I would suggest that you not ...

Should I pickup a BiPAP Auto M Series for $45 (its heater doesn’t work) to see if a bi-level machine would eliminate my end-of-exhalation-suffocation response? I know I’ll probably want better data capability in the future, but for so cheap, wouldn’t it tell me if a bi-level would solve the primary,...

I've tried the control panel for listing my equipment. It hasn't worked. I don't know what I'm doing wrong. I'll try again.

Thanks robysue for the in-depth response. Terms: “ASV” means what? Should I pickup a BiPAP Auto M Series for $45 (its heater doesn’t work) to see if a bi-level machine would eliminate my end-of-exhalation-suffocation response? I know I’ll probably want better data capability in the future, but for s...

Is the machine reversing pressure from exhale to the higher inhale pressure, like it's not following your breathing? By "reversing", I guess you mean "switching" the pressure back to the higher inhale pressure. That's a good question - if, hypothetically, it's not following my breathing, how would ...

To the OP: 3 or 4 cm is as low as an xPAP machine goes. That much positive air pressure is needed to ensure that the CO2 you exhale is properly vented. It's the difference in IPAP and EPAP pressure that can make it easier to exhale with a bilevel. You may find using a PS = 4 or 4.5 cm (which can't ...

Wow. Even for a small, elderly woman, (like me) 4 cm is barely perceptible on exhale. What's going on that you have such a problem with exhale? I wish I knew. Right now I wish I was a small, elderly woman At the end of my exhales I observe that I'm not finished breathing out and the pressure from t...

I was planning on picking up an old cheap BiPAP Auto M Series to 10am this morning, thinking that the exhalation pressure can be set to zero or near zero (as opposed to 4cm, which I can already get to with my current machine with an EPR of 3 and a inhalation pressure of 7). But the manual seems to b...

I should have mentioned that I use the heated humidifier with a ClimateLine Hose. I have no data on my sleep because I can’t sleep with the treatment. So I have no AHI to report. My study said “AHI/RDI at Final Pressre: 0.0/4.2. My current settings are whatever new combination I can think of. When I...

[I don’t know why my machine isn’t displayed - it’s the ResMed S9 AutoSet.] My sleep study recommended 6cm pressure. The incoming pressure prevents me from exhaling completely, unless I conciously push the rest of the air out (which is no good when I’m trying to sleep and my breathing is becoming li...

I'm new to CPAP - I have a machine now but I haven't been able to fall asleep with it on. As I try to fall asleep, I always end up with the feeling that I’m suffocating so I have to take off the mask. It feels like I wouldn’t get the suffocation reaction if there was zero resistance to breathing out...

Very helpful replies, thanks much! So to confirm, any APAP I get I can change the range myself? ...an apap machine is a cpap machine and they can legally be dispensed without a range of pressures being documented on the RX. Is there an authoritative source I can quote to that effect, in order to con...

Hi all, I’m new to the world of PAP, and I’m having trouble getting an APAP unit. Insurance declined to pay for any machine, so I’m paying for this on my own. I've got an APAP prescription from my doctor, but he's not a sleep specialist, which I think is why he won't write a pressure range on the pr...
