Give us a zoomed image that shows the flow rate at a zoom of 2-3 minutes so the flow wave is visible.

Is this what you need?

That's a fair example. We see flattened inspiratory flow leading into an arousal. Flow limitation is not severe here but does flatten out. Pressure appears to be increasing a few tenths here, but that does not really show up on the full night. This is pretty early on in your session, so sleep stage may be light here. The time period around 03:30 looks more obstructed.

Ok, well is that bad? What do I need to do?
RE: new user question about my numbers - pen123 - 01-28-2021
How does that compare to the Resmed? I'm still thinking I might can trade back, even though they won't be happy with me. Really, I don't care. It's my money and my health. I am renting it monthly through my insurance anyway.
Here is the flow chart for the one night on resmed
RE: new user question about my numbers - Sleeprider - 01-28-2021
Both of those charts show that you had flow limitation in spite of the 3-cm EPR, and the pressures were at your maximum setting nearly the entire night, resulting in 10/7 pressure (inhale/exhale). The second chart has an interesting feature where flow limitation let to an arousal and rapid recovery breathing. The pressure actually dropped within 15 seconds, and as the hyperventilation ended, flow limitation was more prominent than before leading into the RERA. The closeup shows a strong tendency for flow limitation which is likely related to upper airway restriction or nasal congestion. We can't diagnose it from here, but no doubt the bilevel pressure was beneficial. Both of these CPAPs are designed to increase pressure when flow rate is decreased like this, but the Resmed acts faster, and in this case was limited by the upper bounds of the pressure setting. When you had the upper limit for pressure set to 16-cm, I have no doubt the machine would seek to take you there. I don't expect you to pursue bilevel, but in your case 3-cm of pressure support is not enough. You don't have apnea, and bilevel pressure with lower EPAP and higher pressure support would likely be your ideal solution.

Thank you for your reply.
Can you put that in layman's terms. I'm sorry, I can't quite follow what you said. I'm still a newbie
RE: new user question about my numbers - pen123 - 01-28-2021
Also, you said I don't have apnea. What do you mean by that?
Thanks!
RE: new user question about my numbers - pen123 - 01-28-2021
Well, I have the Philips respironics Dream Station right now. Should I change any settings. The upper limit is 16 and it does not even go up to that.
If the Resmed would have gone to 16, why wouldn't the Dreamstation? Is it because the Resmed tries to get ahead of the apenas and the Dreamstation does not?
Also, there are a few posts of mine before this one.
Thanks.
Overall, how do you think the dreamstation is doing? Is it good enough not to switch back to the Resmed? I hate confrontation with the machine people. But I can do it if you think there is that much of difference.
