VPAP?

Ok I know what CPAP, BIPAP and APAP are but what is VPAP? I tried doing a search but didn't get far.

Sorry if it sounds dumb but I hadn't seen that term before today.

VPAP stands for: Variable Positive Airway Pressure and it refers, at least for ResMed, to a BILEVEL machine.

SO how is that different from APAP...sorry still confused on this one

I have no personal experience with ResMed units. Various PAP machine makers list their similar, competing, technologies by different naming conventions.

The ResMed VPAP BILEVEL units are competitive with BIPAP units, as Respironics refers to that mode-set of operation. There will be some differences in the technology and how it is is actually implimented in competing brands. They won't all dance identical steps to one given set of musical notes -- but they'll do essentially the same thing with some variances in each brand/model enhancements.

Maybe someone else can explain it better, but that's the gist of it.

Hmmm ok thanks!

The difference is that the BiLevel or VPAP have two different pressures one for Inhalation and one for Exhalation. And if you add auto in the mix they will both rise and fall like the APAP as needed but stay at least 2 cm H2O (At least the Respironics M Series BiLevel others may have a different min set) there is also a max separation that can cause the lower or higher to fall or rise with the other as well. I hope that is understandable. I'm new so I've only ever used the Respironics M Series Auto BiPAP with Bi-Flex, but the others should work similarly.

Hope this helps,

Christy

Ok well if VPAP works like BIPAP then it makes more sense, sounds like maybe it's basically the same thing.

Thanks!

Sorta but whatever I'll sort it out later. I'm just on straight CPAP so the other styles are not something I'm familiar with.

However I was curious as to what cheynes-stokes breathing was so I looked it up, and now I'm sorry I did....it got linked to the "death rattle" in dying patients.

I saw my sleep specialist today as a follow up to my latest sleep study for titration with CPAP and the BiPap which was a disaster with both. He said that since I have central sleep apnea (327) I need the VPAP. He said the VPAP senses when I need to breathe since I apparently don't do that on my own. The CPAP smothered me and the BiPap didn't synchronize with my breathing, effectively cutting me off from breathing when I needed to. Supposedly the VPAP will be more comfortable. So, I don't think it is quite the same as the BiPAP. Hope that helps.

Probably what your sleep doctor was talking about is the VPAP III ASV machine, not just "the VPAP."

BiPAP is Respironics name for its standard basic bi-level machine.

VPAP III is ResMed's name for its standard basic bi-level machine.

Since Respironics was the first manufacturer to develop a "bi-level" machines (higher pressure for inhaling, lower pressure for exhaling) their trademark name for that machine -- "BiPAP" -- became commonly used to refer to any bi-level machine that came along later. Kind'a like "chapstick" became the generic word for any brand of lip balm even though Chapstick is a brand name. And "kleenex" for any brand of facial tissue.

BiPAP, VPAP... both are bi-level machines by the two major manufacturers.

Both those manufacturers also make bi-level machines with more features than just basic "bi-level".

Respironics' BiPAP ST and ResMed's VPAP III STA are bi-level machines that can also have a timed backup rate set. The timed back up rate will make the bi-level machine switch back and forth between exhale/inhale if a person is not taking as many breaths per minute as the rate is set for. Hoping to nudge the sleeping person into resuming breathing sooner during a central apnea than otherwise. The bi-level machines with "ST" (Spontaneous/Timed) were the main ones used to try to treat central apnea until the adaptive servo ventilators (called SV or ASV machines) were developed in the past few years.

Respironics' BiPAP Auto SV and ResMed's VPAP III ASV are more complicated "bi-level" machines. Both are designed especially to deal with Central Sleep Apnea and to handle the central apneas typical of a particular respiratory pattern (Cheyne-Stokes) which is often seen in people with CHF (Congestive Heart Failure.)
