I'm on my third mask & am still having what Sleepyhead categorizes as major leaks.
SleepyHead uses the Resmed RedLine of 24 L/min for determining "Sleepy Head large leaks." In other words, when the SleepyHead leak graph (not the total leak graph) gets above 24 L/min, SleepyHead will report this as a "large leak", even though the PR DreamStation you are using does not necessarily flag it as a "Large Leak."
Quote:The thing is that with all 3 masks I haven't found any leaks between the mask and my face. The leakage is from the vent or the swivel connector.The leakage from the vent is normal.
But you are fitting the mask at the beginning of the night at low pressure. What happens is that as the night goes on, your face relaxes and the pressure goes up. That combination is causing the mask seal to break. And then you get the larger than expected leaks.
One fix: Try to fit your mask at your full pressure, not the beginning (ramp) pressure. FFM are harder to seal properly at 15cm than they are at 10cm and they're harder to seal at 10cm than they are at 5cm.

You may be right but I feel like there's some other reason.
I am a mouth breather - often my nose is blocked but seems to clear while I'm sleeping.
Quote:I generally sleep on my right side & pre starting to use CPAP I was constantly rolling around & kicking the covers off.This is common. A lot of people with untreated OSA are very restless sleepers---essentially your body is moving around both in reaction to the apnea events and in an unconscious effort to find a position to minimize those apnea events. With CPAP, the apnea events don't happen, so the body doesn't need to move around as much.
Now I am not rolling around or kicking & constantly am in that same position when I wake.
Quote:I have had instances when my F20 mask has crept up to where the bottom part of the cushion is partially in my mouth but without air escaping.Facial relaxation can explain how the mask crept up ...
But it is a surprise that this didn't cause a larger than expected leak.
Quote:Feeling frustrated but know I need to just be patient - listen to the advice I receive here & continue to try different masks.Masks are in the nose of the beholder.
I still like the feel of the Amara View - will ask my rental supplier what size they gave me - have printed the sizing chart & am a medium.
Looking at the ratings from supplier 1 I'm thinking about trying the F&P Simplus - but feel it may be the first mask my supplier gave me that I had problems with as well.
What I mean by that: A mask that is well beloved by many may just not work for you. A mask that is hated by most may become your favorite mask. It all depends on the shape of your nose, face, and chin, along with what things decrease your particular comfort in using a mask.
Quote:That's another thing that has frustrated me - my supplier not telling me what's what. I accept that I'm more to blame than them - in that I haven't asked - but that was because I had put my trust in them to look after me & not knowing zilch about CPAP. Now - especially after having my eyes opened here to their obvious need for profit - realise that me being ignorant is what they want.The American profit system works this way: Most DMEs, like most businesses in general, care more about their bottom line than their patients/customers.
