Difference between AirSense and AirCurve

I'm sure if I looked through the posts enough, I'd find the answer, but I'm hoping someone can give me a quick answer. What are the differences between a ResMed AirSense 10 AutoSet
and a ResMed AirCurve 10 VAuto? Why is the second one so much more expensive and is it worth the cost?

Good question. I have the plain resmed CPAP but looking for a spare machine to get more data. Have the opportunity to purchase a used AUTO or CURVE for about the same price. For me it probably doesn't make any difference.

the airsense cpap is a single fixed (adjusted to your prescribed )pressure .... the autoset will self adjust to your needs and the Aircurve series of machines are Bilevel machines ... there are many differant models of the Aircurve ... vauto ... ASV ... S ... ST... ....

The AirCurve machine is a bilevel machine and there's several different models in the bilevel line with various different functions.
All the way from just a glorified Elite/Autoset to a bilevel to breathe for you if you don't breathe on your own.

So there's a lot of differences and one being the AirSense machines are limited to 20 cm while the AirCurve machines can go to 25 cm.
That's not the only difference though...just one of many differences.

The Airsense10 line are the fixed pressure models, the best being the Autoset that can adjust constant pressure within a set range to adress periods of time when more or less constant pressure is needed to keep the airway open. It only treats obstructive apneas.

The Aircurve10 VAUTO in particular a bilevel (some call it a bipap) machine, meaning that it is capable of a large discrepancy between inhale and exhale pressures. It's only for people with obstructive apnea who have such a high inhale pressure that they aren't comfortable breathing against that inhale pressure, so when the person exhales the machine drops the pressure a lot to make exhalation easier.

So one wouldn't switch from an Autoset to a VAUTO unless the Autoset wasn't working for you and you had a sleep study indicating a bilevel machine worked for you.

The Aircurve10 line has models that treat a variety of problems other then just obstructive apnea, like the ASV model that also treats Central Apneas.

Search around, it's good to know all the curent models and what they treat and and how.

And always get a good back up machine that comfortably treats your type of sleep apnea.

Thanks everyone. The info is helpful.
