AirCurve VAUTO vs AST - DayWalker - 05-14-2020
Hi there,
I wasn't sure if I need to post a new topic, but anyways.
Is there any chart comparing VAUTO vs AST? Does AST support all the modes of VAUTO i.e. VPAP Auto BiPap, etc?
I reviewed a few topics on the forum boards, but it is not very clear to me.
Also is there any definite way to tell if one has OSA or CSA besides the symptoms?
Thank You.

I think you mean ASV (adaptive servo ventilator), and it is not similar to the Vauto. The Resmed Titration Guide discusses the application of all types of machines, the conditions they treat, how they react to events and how to titrate pressure. Start with this https://www.resmed.com/ us/dam/documents/products/titration/s9-vpap-tx/user-guide/1013904_Sleep_Lab_Titration_Guide_amer_eng.pdf

Yes, to determine this you need an all-night sleep test, preferable a polysomnography test, which will measure your brain waves along with heart rate, respiration rate, oxygen saturation levels in your blood, sleep posture, and movement of your limbs.
There are home polysomnography tests, but more commonly they are administered in sleep labs -- probably not on during the corona period.
You can also have a home test that does not measure brain waves, but that is going to yield less useful information. (That's what I had, via Kaiser. It turned out to be good enough to tell me I needed CPAP therapy.)

Thank You Sleeprider, very helpful info.
Dormeo,
I did this sleep study at home, 2 belts around my chest and abdomen, oximeter and nasal tubes all hooked up to a recording device that recorded everything i.e. posture, movement all the sensors and voice. No polysomnography was done i.e. no brain waves.
The pulmonologist didn't say anything about CSA but noted that he thinks CSA and maybe OHS but not sure. Well, the 'maybe OHS' is a different monster, different machine and different things than OSA... He said let's start with APAP and see how it goes. He just handed me an oximeter for my Airsense to monitor myself for 10 days.
I am still in my honeymoon period with my APAP and judging by the numbers it couldn't have been better but I just want to be thorough and know everything, since there is nobody else who is more invested in my health than myself alone... and I'd rather spot errors earlier this time rather than be on treatments that do more harm than good as it happened before.
Cheers,

In general, the indication of Centrals, CA events, on your CPAP is considered to be sufficient.
RE: AirCurve VAUTO vs AST - Dormeo - 05-14-2020
DayWalker, are you using Oscar? If you'd like to share a chart, you might get some more feedback.
RE: AirCurve VAUTO vs AST - DayWalker - 05-14-2020
Bonjour, I got confused. Do you mean that me having CA (Clear Airway) events on my CPAP it indicates Central Sleep Apnea?
Dormeo, please look at this post. http://www.apneaboard.com/forums/Thread-Is-CPAP-treatment-that-good-or-something-is-off-with-me

Yes, CA events ARE Central Apnea events. Yes, it is possible to find a few that are actually obstructive, and OA events that are really CA events but on the whole, they are what they say they are.
Because the CPAP is not monitoring chest or belly expansion or EEG activity some vendors call them Clear Airway (meaning no restrictions) because they don't capture the lack of effort part required to call them Central Apnea. So CA = Clear Airway = Central Apnea

Bonjour,
This means I have both and there are days where Oscar shows me I have more % CA than OA... overall a third of my readings for apnea are CA events.
Here is a snapshot (I've cut it this way, since there was old data (not mine) on the SD card when I rented it and I imported it by mistake) This shows last Week...

Your numbers are such that you will not qualify for an ASV.
