started to get a lot more centrals, questions

[airwaystent]

Hi,

Here are my charts for the past few days: https://imgur.com/a/4AJVh9K

I tried decreasing the PS, but I felt awful the next day. 5.5 PS is what I need, I tested it for a long time and that what works for me. So decreasing PS is out of the question.
If centrals go above 5 I feel tired the next day. Anything below 5 is acceptable for me. How do I solve this?


I feel sometimes when  going to sleep that the effort is there to breath, however the machine doesn't pick up on it properly, so I just breath in with the EPAP pressure.

My current machine is quite old, system one biflex.

I ordered a ventmed ds7 as a backup and it should arrive soon.

My therapy is quite solid. I very rarely have bad days. But I still don't feel good enough to excercise regularly for example. I am fairly young, 27.

I feel that I probalby don't need an ASV as my centrals are not very high, but I need to optimize the bipap therapy.

Do you think that ST mode will/can help? I read that it's not really tolerable by most people.

What do you think of the APCV mode? Can it help with centrals? I tried reading up on APCV, but there is not a lot of info out there for it regarding sleep apnea/uars

It is a bit difficult for me to read the charts on Imgur, but from what I can tell your current machine looks to be at its limits for helping further. If it is quite possible acquiring a ResMed AirCurve 10 Vauto would be a better choice, specifically as it has additional features for triggering the transition from IPAP to EPAP or vice-versa.

In your case you may have a weaker inspiration signal or need more inspiration time, which would point towards needing a higher sensitivity trigger. If you need a more complete expiration we would go to a lower trigger setting. If you can acquire a new machine, I suggest keeping the same pressures to start and setting trigger to high or very high. Depending on how that goes folks can tweak further from there.

Hi, thanks for the reply.

My new machine (ventmed ds-7) is coming in next week.

I can see it has settings which you have described (see attachemnt)

What is the difference between INSP trigger and INSP. sensitivity?

Based on the manual I could find for that device, it looks like lower numbers are more sensitive and higher are less sensitive. You can try going with an inspiration trigger of 2, which may be similar to ResMed’s Trigger set to high.
