AdaptSV vs BiPAP SV

[StillAnotherGuest]

So, I guess it's gonna work on analysis of the flow waveform, but it's still gonna have to have a floating window to calculate a target:



I don't know where they got that "Adaption phase 40 minutes" for AdaptSV, it takes a heckuva lot less time than that.

That mask recommendation thing is screwy too. AdaptSV has the options for 4 masks, and other masks could very well be quite acceptable. But I very seriously doubt that ANY ASV machine will work with interfaces with significant restrictions (like a pillows-type of deal).

And leaks? Adapt SV runs quite well in the face of leaks more than 24 LPM (and that must be in addition to Exhaust Rate, which has got to be 30-35 LPM anyway).

Yeah, lotta mode, pressure and rate options for BiPAP SV.

I'm thinking we're gonna need a head-to-head, looking specifically at the ability of each machine to address the other 's failure to manage-- and I'm talking patients, not events, because I'll bet that BiPAP SV will have the same difficulty with Wake/1 transitions and poor sleep efficiency (creating unstable baselines) that AdaptSV has.

So when will we start seeing it use?

Thanks for the info SAG.

Seems CO2 manipulation still plays a part in this treatment with these version of machines (i.e. mask limitations). You would think the Activa would have plenty of dead space, but I guess that bellows cushion must "soften" any pressure response too much.

Do you think these new machines really work all that much better over cpap or do they just do a better job at avoiding any response to central events?

With the AdaptSV's 10cm limitation it seems they are partially still relying on the A10's algorithm, could be wrong though. They make some pretty bold statements claiming to address all forms of centrals, but I haven't seen anyone else back up that claim as of yet. Could be they haven't released the machine yet for that to happen. I know they have been testing a few.

You have given me a idea, I switched this week to the Activa, and have notice my snore level went down, a lot on APAP. Everything else stayed about the same, pressures were more level due to the lack of snoring. I think you are probably right about the mask softening the pressure responses, nice catch. Jim

Hmmm, got me there, christine.

We might need a road trip (to like Frankfurt)(and I don't mean Kentucky).

We'll go halvesies on the gas. I figure it'll be about $2315.85.

I'll get the tolls, I've got an "E-Z Pass."

Can't wait to open up the ol' Dodge Caravan on the Autobahn!

Apparently, soon.

Respironics gets FDA Bipap OK
March 7, 2007

MURRYSVILLE, Pa. --Respironics Inc. said Wednesday that the Food and Drug Administration granted marketing clearance to its Bipap autoSV device for people with breathing problems during sleep.

The Bipap autoSV is a ventilator for people suffering from obstructive sleep apnea and respiratory insufficiency caused by sleep apneas. Sleep apnea is characterized by blockage of the airway during sleep by excess tissue such as large tonsils, a large tongue or airway muscles that relax and collapse during sleep, or blockage in the nasal passages.

The device uses software to recognize breathing abnormalities and correct them when they occur.

Respironics already sells the Bipap autoSV in Europe and Canada, markets where it has been well received, the company said.
