Traditional Cpap vs Apap
I'm curious about the different specifications for machines. I was started off with apap from the beginning so I understand how that works.
Do many people still use the traditional cpap or have most people switched over to apap? Is there a reason some need to stick with cpap?
And then is bilevel different from both of these?

cpap levels you out so that you have the same minimum pressure as maximum pressure. you could, for all intents and purposes, turn your apap into a cpap by just changing one of the pressures.
i'm not entirely sure if people coming fresh to sleep apnea are prescribed cpap.
there are a few people who come by here who use cpap only.
forum member wulfman comes to mind.

Re: Traditional Cpap vs Apap
In Ontario, Canada, it is very difficult to get prescribed an APAP machine under the ADP program.
One must meet the following eligibility criteria:
Yes.
Historically, BiLevel was the ability to deliver different pressures depending on whether one was inhaling or exhaling. Now, most modern day machines are capable of limited BiLevel ability (approximately 3cm).
Typical differences between BiLevel and traditional APAP/CPAP are:
One must meet the following eligibility criteria:
- Sleep study documenting OSA
- Require 10 cm or more
- Require a difference of at least 4 cm (or more) between REM v NREM or Supine vs Non-Supine sleeping
Yes.
Historically, BiLevel was the ability to deliver different pressures depending on whether one was inhaling or exhaling. Now, most modern day machines are capable of limited BiLevel ability (approximately 3cm).
Typical differences between BiLevel and traditional APAP/CPAP are:
- Greater difference between between Inhale (IPAP) and Exhale EPAP support.
- Greater ability to deliver more pressure, most modern day APAP/CPAP can deliver up to 20 cm. BiLevel up to 25 cm
- Greater ability to configure the characteristics of EPAP and IPAP pressures.

according to passport-in-hand, you don't give out any helpful advice.
sure hope he doesn't see this!

Re: Traditional Cpap vs Apap
Some folks are woken by variations in pressure. At least one member here had problems with high blood pressure using an auto-cpap although I don't think anybody knew why. Some people do not have apnea at all but use the machine to assist breathing (ex: reduced lung function). Many docs STILL set patient machines at the 'ideal' pressure. Nobody here stays with THAT very long.ILoveFlowers wrote: ↑Tue Jun 15, 2021 2:01 pmI'm curious about the different specifications for machines.

Re: Traditional Cpap vs Apap
Since APAP machines can be configured for CPAP only mode, there really should only be APAP machines made. I have a feeling CPAP machines are APAP machines with functionality disabled by the manufacturer. Makes no sense to make two different circuit boards. Would be more cost effective to make just one.
The Canadian requirement makes sense reading it. Don't know how it applies practically though.

Re: Traditional Cpap vs Apap
As long as insurance companies insist on lowest possible cost for "effective" treatment, they will continue to make single pressure machines.southerndoc wrote: ↑Tue Jun 22, 2021 8:42 pmSince APAP machines can be configured for CPAP only mode, there really should only be APAP machines made.

Re: Traditional Cpap vs Apap
Apparently I’m a dinosaur who uses only cpap. I started out five years ago, as instructed by my doctor, with an auto pap setting of 8-12. Many problems ensued with many degrees of pressure settings changes. Eventually, after reading discussions here, I felt I might be among those light sleepers who were constantly awakened by the automatic pressure adjustments made by my Dreamstation. I’d either wake up feeling bloated or hiccoughing (too much pressure) or with a headache (too little pressure). I finally settled on plain old cpap with pressure set between 7.5 and 11 and I started using Bleeps (great invention)—yay. Now I’m sleeping great and my AHI has gone from 9 to .5. Of course, now with this recall, the Dreamstation is out. Tonight I start using the ResMed Air Sense. I’m trying to set it up as we speak.

Re: Traditional Cpap vs Apap
Oops! Sorry, I had a brain collapse. I USED to use straight cpap, but have since gone back to Autopap with a much more limited pressure setting and good results. You can completely disregard my former message. Apologies for having a senior moment.

The Airbreak project (reflashing firmware) from a year or so ago demonstrated that BiLevel, Auto, could be installed on all AirSense 10 devices.

With a exceptions of a few brief periods when I experimented with ranges of pressures, I've used straight pressures (CPAP mode) for the entire time I've been on this therapy.
My experiments with ranges of pressures confirmed that my CPAP pressure is optimal.
I also have all of my APAPs configured to straight pressure mode.
Reasons I don't use ranges of pressure are:
I have very few flow limitations, hypopneas or apneas. (almost NONE of any of those)
I have "some" snoring but those events aren't in any proximity to my hypopneas or apneas.
I see no reason to allow my machines to chase an occasional errant breathing anomaly for no benefit.
I found that pressure changes can disrupt my sleep.
Straight pressure is by far the most comfortable for me to use.
My AHI typically averages about 0.2 - 0.3 over a month's time or over a year's time.
Why change when you find out what works well for you?

I've got a Resmed S9 that does everything. (Look up VPAP Tx)
