Comments on ResMed AutoSet Spirit

Does anyone have experience about ResMes AutoSet Spirit used for titration?
That machine gave me 12 cm H2O treatment pressure.
How well does it do the job if central events are of main concern?
I guess it handles obstructive events well?

Is it normal that breathing feels like after exhaling the lungs are full and after inhaling
the lungs are "stretched".

Oh, fudge!! I keep getting the various Resmed model names mixed up between North American model names and other country model names.

I "think" the Resmed S8 AutoSet Spirit is the equivalent of the North American Resmed S8 AutoSet Vantage (or vice versa)??

If so, nope, it can't differentiate central apneas from obstructive apneas. Yup, it handles obstructive apneas very well and typical (so they say) to Resmeds they do score hypopneas a little more aggressively than some of the other manufacturers' models.

It isn't unusual to experience some chest discomfort when first using an xPAP or a drastic change in xPAP therapeutic pressure and that discomfort CAN feel like the lungs have been "stretched".

None of the APAP systems can do anything for a central apnea. They will a treat a central apnea as if it was an obstructive apena and act accordingly (see below).... which depending on the circumstances may not be the best thing to do.

Most APAPs will not do anything in an apnea occurs without some proceeding flow limitation events, on the basis that it is most likely a central apnea.

If you are just starting out on xPAP tretament, it takes a while to get used to different "feeling" of any positive air pressure, however the pressures involved with xPAP tretament are in fact very low and are not going to be stretching much anything in your lungs.

It seems to me that you need to tell us more about exactly what your situation is, and what your concerns are!

Unlike most machines, the Puritan Bennett 420E and the Sandman Auto will identify some central apneas for some people. In those case of identified central apneas they will simply not raise the pressure.

That's what it seems to me too.

First, thanks for quick replies.
I'm going to the sleep policlinic this morning, and I needed this info for that.
I had my sleep study about 2 weeks ago and I don't have the report yet, so
I guess I don't have the further info to you yet.

The clinic was part of a teaching hospital, and I was selected as an example for the students,
so I was there when the doctor explained the curves to the students, so I got to know
little something but not much due to the jargon.

Maybe I'll get the report today. At least I hope.

The Resmed AutoSet Spirt (S7 and S8 models) will not respond to frank apnea at or above 10 cm pressure. So if you need
12 cm to prevent apnea, the only way the machine will prevent that is by moving the Minimum pressure up to
the pressure that eliminates it.

At or above 10 cm pressure the Spirit will only respond to Flow Limitation and Snores. Not responding to apnea above 10 cm
is by design, it is part of its A10 algorithm part of AutoSet. Since it cannot differentiate the difference between a 40 second
obstructive apnea and a 40 second Central apnea it elects not to respond to either.

Other Autopaps will respond to apnea at or above 10 cm, including 420e, Sandman Auto and Remstars.
