Poll for PB420E users: is IFL1 on (default) or off

I'm trying to find out, and figure out something, and need an answer: What is your IFL1 (in the software) or FL: (on the screen) set up as?

It is my impression that actually more of us need it off than on -- bear with me while I mull about those things.

If you don't know, press the leftmost button on the machine for a second or two, and scroll through the settings with this button.

When you reach FL:

• 1 means on
  0 means off.

Thanks,
Mine is off.
O.

I just got mine. It's on. I haven't turned it off yet. I haven't had a reason yet. Perhaps once I view the software occasionally I'll see a reason to turn it off.

Any suggestions on the humidifier setting? It came on 1. Last night was severe dry mouth and at one point my nose got so dry it was starting to get painful. I was thinking 1 increment at a time but I'm upping it to 3 and see what that does.

It's taking some getting used to. I keep forgetting to turn off the humidifier because it turned off automatically on my Resmed S8. Little things. But completely different.

I had to turn it off, too...thanks to help years ago from -SWS.

Even though you and I have perhaps paid more attention to posts where people have mentioned having to turn that setting off, ozij, I would think the majority of 420E users are ok with it left at the default setting of "on."

I can't imagine that after the 420E being out so many years, it would still be coming from the factory "on" if that trigger were not fine for most people. However, stranger things happen, and unless DMEs actually noticed unusual pressure climbs and said something to the company.... so, on second thought, yeah, I guess I can imagine.

Speaking of "majority", my bet is that the majority of people out there use their machines and never know what's happening, what could happen, what to look for, or have the software, or...even care. No matter what brand or type of machine. They usually don't even know the brand name of their machine, much less the model.

Perhaps a good many DMEs did hear "high pressure complaints" from people who were experiencing IFL1-caused runaways, but the DME didn't know why it had happened. They only knew that the machine didn't seem to be operating as it should and may have simply dropped 420E's from their inventory in favor of machines that didn't bring that particular complaint through the door. IF that was happening, I can see how a DME that doesn't know about IFL1 would figured there were just a lot of malfunctioning machines in that brand.

I doubt if most DMEs who have given out 420E machines ever do a download, much less look past "yeah, he's using his machine enough hours." Or even would be aware of what IFL1 might be doing or what to look for. You could probably count on the fingers of one hand how many DMEs in the past year have even glanced at the 96 hour graph if they did do a Silverlining download at all.

One of the reasons I backed off several years ago about suggesting a 420E to people -- even though I liked the machine (and still do) very much -- was because of IFL1 being on by default.

Even though I thought that was probably an ok setting for most people, there were enough people reporting on the message board that they had had to turn it off...well, just seemed to be "enough" of a problem that I wasn't comfortable recommending it much without going into a lengthy explanation of "BUT be sure you get the software, too, and here's what to look for..."

By the time the words "possible pressure runaway" would have been written...LOL!!... might as well have saved the typing and just recommend another machine I liked very well.

All that said, I would definitely recommend a 420E autopap. If the person is also going to get the Silverlining software. Or if a DME is going to do a download within the first days. And IF the person or the DME is well aware of what IFL1 "on" can do...and what to look for to see if that trigger is ok for that person.

my IFL1 is also unchecked or off.

My understanding is that is "command on Flow Limitation" or should I respond to stand-alone Flow limitations,

IFL2 is command on Flow Limitation associated with Hypopnea. That one should remain checked or it may not respond to FL at all.

Topic started by -SWS accidentally logged in as "Guest".

Even though that topic starts out talking about the ResMed Spirit autopap, the topic moves quickly into a very thorough discussion about the PB 420E autopap's IFL1 and IFL2 triggers. It's a "many pages topic", so keep turning the pages!

It's because I'm aware of this the I decided to ask. At least I'll know about our little group here.

Yes, so can I.

Perhaps a good many DMEs did hear "high pressure complaints" from people who were experiencing IFL1-caused runaways, but the DME didn't know why it had happened. They only knew that the machine didn't seem to be operating as it should and may have simply dropped 420E's from their inventory in favor of machines that didn't bring that particular complaint through the door.

Great idea, never though of it like that.

That's exactly my point "enough people of the message boards"... makes you wonder how many. Of coures one can always say the the PB, being the smart little machine that it was had everyone satsified - except for the small group who need IFL1 set off and went to search for help on the message boards....

Any way, it never hurts to have data.
Of IFL1 usage, in this case....

O.

Umm, hmm ... I seem to recall not too long ago, in a meandering thread, somebody mentioning that equipment manufacturers might be as out-of-touch with patients as DME's and physicians appear to be. .

Kinda looks like evidence here in support of that perspective. If, as appears likely now, the majority of PB420E users on this forum have changed that troublesome FL setting, I'm inclined to think the result extends to the much larger patient population as well. The reason I think so is because I bought my PB420E as a backup machine, primarily to be used when traveling. I know others here have indicated the same reason for getting the machine.

Changing that FL setting is actually a big deal. It seems very unlikely that folks here would have changed the setting without a reason. I just can't envision the average forum member deliberately changing FL settings without a good reason. Experimenting maybe, but if that were the case, then the distribution ought to be about 50/50. Changing the FL setting requires one to know of the need for a change. In my case the first night or two was a problem. From prior reading here I knew there was a potential issue and so I then searched for the thread which provided an explanation (or something like that).

Mine's off. I found my pressure kept getting higher and higher also. I use it as my traveling machine. The only complaint I had with it was the little nub for the hose broke off on my first one. That was a pain-- but it's still a wonderful machine (with fl1 off).

Thanks to you guys on this board!

ozij, I don't know if these people were among the "turned it off" voters, or even if they still read the message board... but anyway, here are a few who had reported in the past that they turned IFL1 off:

Thanks for that additional info, RG.

I ran a short test recently - turned IFL1 on for a nap - was wondering if using an Initial pressure higher than the Minimum would make a difference - none at all.

Anyway, I'll keep this poll alive for a while...

O.

bump.

tangents?
Eleena?
Ms Piggy?
Echo (IIRC yours is on)?

Or have you voted already without posting?
O.

Mine is still on. I never understood what it was so I left it the way it came. Now I understand(somewhat). Think I will leave it on since my therapy is going well.
