Hello. Thanks for the months of info and browsing (i love reading everyones stories and tips n tricks!) .

So over the past year i have tried all sorts of things. Nose pillows, FF masks, mouth tape, chin strap. The usual. I have recently settled on a Phillps dreamwear full face mask. I think i'm on the right path - i just need some help deciphering OSCAR data. The leakage has always been an issue, so i have been dialling that in recently. Any help or tips would be appreciated.

I don't think your setting are all that bad. Your main component, based on this one night, of AHI is obstructive apnea. It looks like you have Flex turned on. The first change I would try is to turn the flex off. It can make obstructive apnea events appear more often for the same fixed pressure setting. If that does not help, then next you might want to try 10.5 or 11 cm for your set pressure to see if that helps any. More pressure can initiate CA events, but it looks like they are OK for now. As for the leak rate the DreamStation machines display both the total leak rate (upper green trace in the graph) as well as the real leak rate. The top trace includes the intentional purge leak rate for the mask plus unintentional leaks. The bottom curve is the important one as it is the real leak rate where the intentional purge flow is subtracted out. Short story is to ignore the top curve and pay attention to the bottom one. I don't think the leak rate is too bad. If you right click on the Leak Rate vertical scale it should bring up a menu of options. One is to display the Leak Rate Red Line. If you turn that on, it gives you a better idea of where you stand for leakage. I believe it is set for 24 L/min. The Statistics section shows you are over the redline 5.5% of the time. I try to keep that number to 1% or less. You may want to set the scale of this graph to a maximum of 50 so it displays the more useful bottom trace better. Doesn't matter if the total leak rate trace goes off the graph as it is kind of irrelevant.

Hope that helps some. If you have questions, post again...

Thankyou so much for replying. I will try turning the flex off first, then post results. Then tackle other issues. I'm in Australia, so I assume in a different timezone, but we'll work it out.

It's been so hot here, any form of sleep is hard at the moment. Thankyou!

Hello! Have posted last nights OSCAR reading. I spent last evening reading and doing some adjustments as i'm having some ear issues - not pain or popping, just feeling a bit a deaf. Just feeling like there's too much pressure on the exhale maybe? Not sure. So i left my pressure at 9, i might ramp that up to 10. I added back in the ramp and have changed to c-flex+

It was a pretty good sleep overall. I don't feel 100% , but assume after so many years of untreated apneoa - things are going to take time. Any advice or tips would be appreciated. Thanks!
