Feedback please on Resmed "For Her" compared to your old pap

SewTired...can you redo the screen shots and include the flow limitation graph please?
I suspect the increase in pressure that you see is in response to flow limitations of some sort. FLs drive the pressure faster than anything it seems.
On the top image if you look close the increase in pressure started just before the obvious marked reduction in air flow.

Look closely at your other times where the pressure starts climbing around the flagged event...see if you have any FLs going on.
The auto algorithm is designed to respond to snores and FLs fairly aggressively because they are the precursors to apnea events. The machine tries to prevent the collapse that usually is preceded by FLs. In its little brain it senses snores or FLs and thinks...ooops something isn't right so I had better get to work and increase the pressure and hope I prevent a full apnea.

Ok, done Pugsy. I also noticed that there would be changes in expiration or inspiration graphs just prior to some of the pressure risings.

Thank you SewTired.
I think that it was the flow limitation that caused the pressure increases...at least on these 2 occasions.
The pressure was already trending upwards before the last part of the obvious drop in air flow that earned a flag.
Everything I ever read about the algorithm in apap mode has always said that the machine will increase for flow limitations and snores. It doesn't do anything during an apnea and in fact more than one apnea is needed within a certain amount of time before the machine will respond UNLESS there are also the other things that drive the pressure..FLs and snores.

While having an apnea just happen out of the blue without any sign of an impending collapse wouldn't be impossible most of the time there is is likely going to be some little something or some sort of a physical warning sign that the airway is trying to collapse.
This is why apap machines respond so aggressively to flow limitations and snores.
We can't always see the very subtle changes in our breathing that might cause the machine to respond.

sorry...tried putting them in between [img][/image] and it just said image.

that's because you're not selecting the right link. for it to be an img, the link has to end in .jpg or .png etc.

in the two she posted, if you look carefully at the mask pressure trace, I believe that the pressure doesn't increase till after the apnea. it's hard to tell, since the trace is so squished.

I see what you mean.
I was just going by the regular pressure line graph.

SewTired could you remove the leak graph and the flow limitation graph and make the mask pressure graph larger so we can see the mask pressure in larger scale? You could make the events graph smaller to give you more room.

No need to replace the ones you already...just add the new images in a new post. I would like the others to remain available for viewing.

I think we're seeing the difference in 'target pressure' (regular pressure trace) and actual pressure (mask pressure). the target got bumped a tiny bit, probably due to the flow limitation, or maybe a snore, but other stuff was going on, and so the pressure didn't actually increase...

Sorry for delay Pugsy. I just did the 5/9 one. I hope this is what you were describing that you needed.

make it the same time period as the first ones, but change the y axis on the mask pressure trace from auto to a min of 9 and max of 12.

My CPAP for her, Resmed 10, malfunctioned and "caused" hypopneas and other problems (irregular heartbeat). ABC Health Care did worse than nothing to help. They said it was working correctly. They refused to check its functioning multiple times. When it was finally proven to be defective, they refused to provide me with a properly functioning machine. They sent me home (finally after over a month of begging for help) with a Moaning machine, so another malfunctioning machine. They finally supplied a loaner after another month that is causing me to wake up "panting" quickly like a dog! I hate the "ABC Health Care" here in Hampton Roads, Virginia. They refuse to test this current malfunctioning machine, refuse to replace my original machine that was under warranty, and keep giving me crappy malfunctioning machines, then argue when they malfunction. End result and my words to you, fight to see the detailed report for your machine. A tech should be able to pull it. Then fight like hell to get a properly working machine-I had given up-just tooooo damn tired! Obviously I am on here looking for answers. Your problem sounds like how mine started with my malfunctioning machine.

If the machine you have has a data card and can collect detailed day, you need to install the free software sleepyhead. See the Pugsy's sleepyhead section in the announcements of this forum. Then you can use imgur to post some images so we all can try to help out. This sounds more like poor adjustment than malfunctioning machines to me. But without data ?????
