DreamStation CPAP Pro with Auto-Trial IAH

Hello, the dealership company has provided me with this CPAP DreamStation CPAP Pro with Auto-Trial, before giving it to me I bought this AirSense 10 AutoSet device.
The difference in therapy between one and the other has me intrigued, the DreamStation cpap gives me much worse data than the airsense, in the DreamStation machine I hear the internal motor through the Dreamwear full face mask and in the airsense I don't hear anything. any ideas . sorry for my English

Welcome!

Hypopneas account for the main differences between the AHI numbers you're getting with the two machines. Both machines are set with a fixed pressure of 8, and the ResMed machine is set to provide EPR of 1; the PR machine is set to provide no Flex (the rough equivalent of EPR).

It's possible that the EPR is beneficial for your hypopneas. It's also possible that the algorithms for the two machines are working with slightly different ways of scoring hypopneas. I tried to find out on the web whether that's true, but I didn't see anything that helped with that question. Maybe someone else will know.

Do you have better, more restful sleep with one machine rather than another?

Have you ever tried Apap vs Cpap mode? With more options for adjusting min. and max pressures, etc?

With the auto cpap I don't know what parameters I should put in the clinical menu

People here would be happy to help you with that, but first could you tell us whether you feel better with one of the machines, and if so, which one?

Thank you for answering. The health insurance company is the one that provided me with the DreamStation CPAP Pro with Auto-Trial. I bought the Aisense 10 Autoset CPAP, and I feel clearer and less sleepy with the Resmed Airsense 10 Autoset. My prescribed pressure is 8 with a 20-minute ramp at 4 and the AHI index before the start of therapy is AHI 48.9/h

By all means keep using the ResMed machine. You can think of the PR machine as your backup.

To get some more information, I'd suggest making two changes to your settings.

First, turn off the ramp feature. I suspect you won't miss it. You don't get event data at a ramp pressure, and a pressure of 4 is probably not delivering much therapeutic benefit.

Second, switch to Auto mode and set your minimum at 8 and your maximum at, say, 12. I doubt whether the machine will go as high as 12, but it would be useful to know where it does want to go if you give it a little latitude.

After you make these changes, give them a couple of nights before you post a chart so we can see what's going on. Oh, and when you post your next chart, would you include your flow limitations graph? You can squeeze it into the screen shot by grabbing the gray bars that separate the graphs and pushing them up a little.

Hello, thanks for answering. following your advice.

It would be helpful to know how rested, or unrested, you felt after each of these nights. Could you let us know?

Using the zoom-in feature of the SleepHQ charts, I can see that a fair number of your OAs appears to be you holding your breath during a period of arousal from sleep. Because you're not truly asleep, I'd suggest you discount these.

Your pressure goes up in response to the flow limitations, which at times are heavy. Some people are not at all bothered by FLs; others are.

You are doing a fair amount of leaking. Do you know how it comes about? Do you suspect that leaks wake you up?

I would suggest introducing some EPR to see how the FLs respond. So try raising your minimum to 9, and set EPR at 1. When you exhale, your pressure will drop by 1; by the same token, when you inhale, it will increase by 1.

There's a fair amount of experimentation involved in finding optimal settings, so I hope you can bear with this. Meanwhile, do let us know how you've been feeling.

Cybor, a p.s. Could you fill out your profile to show your mask and your (ResMed) machine? Thanks!

profile edited yesterday I felt sleepy, today I'm better, I'm going to follow the advice. Today it seems that the index is doing better and I am clearer. I will follow the advice and tomorrow I will post with the new parameters.

I wrote a few days ago to my medical insurance company an email complaining about the Philips machine and the next day they provided me with a resmed airsense 10 autoset

Apnea Hypopnea Index 0.72

I'm glad you're feeling better, and I'll be interested to see how things go with a little EPR (and the raised minimum). Thanks for filling out your profile, and congratulations on your success with your insurance company!
