Hi both
Thanks for pointing me to that ASV pdf - some very useful info in there! It's fascinating to see the differences in how Philips vs ResMed titrate ASV.
Attached is my results from last night's session (OSCAR). The settings have been adjusted to Philips' own recommendations and are 1cmH2O lower on both min EPAP and min PS (8/4 vs 9/5) than those I've found to be the best in the past in terms of basal spo2. There is plenty of headroom for the machine to be able to bump up the EPAP and/or PS where it needs to... though as you say it never seems to push the IPAP past 16cmH2O at any point which seems a bit strange, instead it just allows my MV to hit the floor before it takes any action.
I disabled the ramp and bi-flex entirely - I'm pretty used to the machine now so this didn't present me any difficulties in getting to or remaining asleep.
The sharp spo2 drop you see at 7:33am is a false reading, my Rad 7 alarmed at that point saying the perfusion index was low as the adhesive sensor on my finger came a little unstuck. You'll see I disconnected for a few mins at that point to use the bathroom. Other than that they're all correct - the drops in pat. triggered breaths correlating pretty much exactly with when I remember falling back to sleep.
Overall (albeit to my untrained eye!) the results are consistent with what I'd expect from previous sessions. My TV/MV always nosedive then recover to a bit less than ideal ranges for the rest of the time I'm asleep. I do wonder though, as I mentioned before, if the 'recovery' part isn't delivering enough pressure to account for my physical size given it's only working within a 4 minute moving window
If there are any particular sections of interest you'd like me to zoom in on let me know the start and end times and I'll post another image
Still v. interested to know how confident you are these particular issues would be addressed more effectively by using the ResMed which targets the MV - if it's almost certainly going to be better I'd see what I can do to try and obtain one, but for me it'd be a case of having to purchase a refurb and sell the DS I have now I think.
Once again thanks so much for your expert opinions!!
