Any of the Flex options will reduce the pressure upon exhale but it is no where like what EPR does.Always tired wrote:Quick question re flex 1,2,3 and my PRSQ 1
In my provider manual it shows me how to adjust flex--no problem and the current setting is 2, but unless it's just massive sleep debt I could swear that I read, maybe in another manual, that pressure had to be a min of 6 to use flex.
My pressure is 5-8 and I have been burping, passing gas since starting PAP. I always thought it just came with the territory. Does flex mean that it's easier to exhale? Just bump it to 3 and see what happens?
It's not a 1 cm drop per setting like EPR is. Instead it is based on your own air flow...force of your own breathing.
While a setting of might offer a little more reduction than a setting of 1...it isn't like EPR. The amount of reduction is based on the flow

If you look at the bottom of the graph in little letters it says minimum pressure of 6 cm to enable AFlex.
I don't see a mention about CFlex though.
It's really hard to explain but to me it felt more like a rhythm thing. Setting of 3 made me feel like the machine was wanting me to breathe too fast...almost like I was on the road to hyperventilation. A setting of 1 made me feel like the machine was dragging up the rear...too slow. A setting of 2 was just right...felt like normal breathing rhythm..barely noticed the pressure. This was AFlex. Now CFlex...I couldn't tell it did a darn thing no matter what I set it on. So I just turned it off. This Flex stuff is really going to vary with an individual...what feels great to me someone else might hate.
But don't confuse it with EPR because it is totally different.
I have tried EPR on my VPAP in straight CPAP mode.....it is totally different feel on exhale...big drop on exhale.
Not uncomfortable different from AFlex...but different.
With minimum of 5...I don't think you are getting any exhale relief. It isn't enabled unless minimum is 6 cm. At least AFlex.Always tired wrote:My pressure is 5-8 and I have been burping, passing gas since starting PAP. I always thought it just came with the territory.

There is a demo available of each of the Flex options in the menu under Flex...try each one at each setting to see which one feels the best to you.
