RE: Therapy Result Changes - stevesleep - 08-10-2024
Need guidance please. @Pizza - would be great to get your input on the data.
OSCAR's are attached. Ignore the first 30min on the oscars, as I'm just falling asleep and sometimes adjusting stuff (e.g. if there's leaks, or events). On 5 August, the large leak events in the middle of the night are just me taking off my mask so I have like a reference of when I woke up, in future I'll just turn off the machine and back on instead maybe, I just wanted something to see where I woke up.
SUMMARY OF CHANGES MADE:
- Started on Medium trigger & 3.0 pressure support, could not fall asleep with this.
- Higher pressure support of 4.0 with medium/high trigger was better, however I had a lot of CA events.
- I changed to very high trigger and increased EPAP/IPAP from 5-14 to 7-12. This change removed the CA events fully and started giving me the lowest AHI scores.
NEW CONSISTENT PROBLEM - Waking up frequently.
I've been testing these settings for a while, they have worked much better for falling asleep okay, feeling comfortable, and quite a low AHI.
The new problem I'm running into is I am consistently waking up every 1.5hr or so (perhaps during end of sleep cycles).
I have also tested just trying to go back to sleep after I wake up, and I can do this, however the sleep is very fragmented doing so. Not ideal. So any OSCAR data you see, is me waking up every 1.5hr basically.
If I do not use my CPAP, I typically sleep perfectly fine, with either 1 or 0 conscious wake ups, for 8-9 hours. Good sleep hygeine. Therefore, it's fine normally, it's just with the CPAP.
THINGS I USE: Dual chinstrap, mouthtape, breathe right nose strip. Nasal pillows airfit P10.
POSSIBLE PROBLEM/SOLUTION (My theories):
I am just guessing but... At the start of my therapy, with the nasal pillows, mouth leaking was an issue and would wake me up. Now I use the chin strap and harder mouthtape. However sometimes I do notice air will start coming out of the sides of the mouth. My tongue might get relaxed at some stage of sleep and air may leak into my mouth, causing me to wake up (maybe). I've maxed out what I can do to prevent this. For this particular problem, a test may be to use a Full Face Mask which might make me not wake up, if some air does leak out the mouth at some point.
The full face mask is an option if I can't solve it via advice/adjusting settings.
However do you have any recommendations? Anymore settings I can play with? How does the OSCAR data look like? Goal is to stop waking up so quickly.
Someone told me my exhalation was double my inhalation and perhaps I'm getting too much CO2 which wakes me up, they said perhaps the very high trigger is the issue. Not sure how accurate that is. Will follow the guidance here.
Please help!
