OSCAR screenshot: one night with new mask

[Chalkie]

Thanks again, Sleeprider. 

I did subjectively feel significantly better after one night with a higher BPM = as if I had had a couple of extra hours' sleep - but no better for the last couple og nights.
  
I will print off the extract you quote from Respeioincs to take to the clinic in a couple of weeks. Do you happen to have a link?

I have in fact been using an SCC for several months now.

I agree, it has to be an ASV and I aim to have it within a few months.

An update to my situation, and all feedback appreciated.

I have two CPAP challenges now: to adapt to a new mask and hopefully a new machine.

I tried the ResMed Mirage FX for the first time last night. I immediately liked the feel of it and thought that it didn't leak much, if at all. My subjective impression was of a smoother night's sleep too.

However, OSCAR tells a different story. Please see the first graph below which shows n AHI of 12, and a large leak rate of nearly 30%.

For comparison, I am posting below that the previous night's stats, using the Comfort Gel. To my great surprise, the stats were actually better. I am wondering whether I simply didn't have the Mirage tight enough, or whether it's the wrong size. I will investigate.

Albeit that I still need a new machine, does anyone see anything else in the stats that is of interest?

Both charts show Positional Apnea, which we often refer to as chin tucking. Pressure does not fix this and neither does changing masks. Are you using a Collar? It may be fixed with a pillow change. Removing a pillow if using more than one or a flatter pillow. Read the Soft Cervical Collar wiki linked in my signature.

Hi Gideon

Interesting that the charts show chin tucking. I am in fact wearing a collar and have been for many months since Bonjour pointed it out last year. I am not sure I can safely make it any tighter.

I have been using a hollow fibre pillow so have now swapped it for my spare, feather, one.

T post a zoomed view on the obstructive event clusters so they ca be more closely examined

My consultant is now talking about putting me on the Repsironi cs Trilogy. She says it has an ASV mode.

Would this be a suitable machine for me?

[Gideon]

I would prefer the ResMed AirCurve 10 ASV as we can see detailed data from that in OSCAR but not the Trilogy.

The Resmed ASV equivalent in the UK is the Aircurve CS Pacewave

Above points re@: chin tucking and machine noted.

While I wait for the wheels of the NHS to grind forward (getting new machine no earlier than July) I am pretty desperate for some short term relief. 

I have changed pillows and am using an SSC in an effort to reduced chin tucking and thus Hypopnoeas.

Apart from the obvious point that last night was a bad one for leaks, is there really nothing I could try with the existing machine, in terms of pressure, to help myself?

This from a couple of nights ago:

You will be surprised at your numbers once the positional aspect is eliminated.
Try a different collar and the flattest pillow you can stand.
