I'm not sure what info you all might need. My pressure is 6. Last night's AHI was 7.6. Rest of the week it was 3.4 to about 4.9. Last night was when I switched to my P&K Eson, which I prefer.
Thank you.


The purple line is SleepyHead's approximation of the unintentional leak rate. SleepyHead uses some statistical analysis to get this graph on PR machines.PartlyCloudy wrote:I've been reading Pugsy's tutorials on Sleepyhead and Googled my question, but I'm still confused. Below is a screen shot of last night's Leak graph, which is pretty typical of the other 5 nights (I"m a noob). I understand the gold line means total leaks including something to do with the mask. What does the purple/maroon line mean?
If you don't fully understand what the intentional leak rate built into your mask at your pressure is, then I'd suggest paying attention to the purple curve. You want to keep it close to 0.0. This leak line is a very good to excellent leak line by the way. Practically speaking, if that purple line is almost always less than about 30 L/min, then your leaks are really quite well controlled.And which do I pay attention to?
Nothing wrong with having a spike like this---particularly when you know exactly what caused it. Do you have Auto OFF turned on? If not, you might want to manually turn the machine OFF and then back ON when you wake up and need to take your mask off to go to the bathroom.By the way, that spike was when I got up to go to the bathroom and removed my mask.
It might be useful for us to see the flow rate graph with the event flags on it. If the AHI doesn't settle down to where it is consistently below 5.0, it may be that you'll need to bump the pressure up just a bit. But I'd wait for a week or two before doing that to see if the AHI starts to settle down.I'm not sure what info you all might need. My pressure is 6. Last night's AHI was 7.6.
