Not a Noob but new blower now large leaks
I recently switched over from a PR System One BiPap to a ResMed AirCurve 10 VAuto, not really a move on my part my Sys1 started acting funky and when I called my DME they said they didn't repair or diagnose them and they ordered me a new one and the AirCurve 10 was what my Dr. specifically ordered.
Anyway I've been on it for a month now and I am still seeing silly leak numbers from ResScan 5.3 (just downloaded update). 30 day period is showing a median @ 13.4, 95th % @ 38.4 and a max @ 56.4. I'm using the same personal equipment i.e. mask, chin strap etc. that I've used for years successfully other than the blower itself and was on the Sys1 for 5+ years and on some form of blower for the past 10 + years. I've never seen any leaking like this. On my Sys1 when I reviewed the data or started feeling less than normal I could usually see an increase in leak and change the mask or more recently the cushions out and go right back to minimal leaking for months. My Activa LT mask did not require being super tight just snug with chin strap adjusted in a similar manner.
I updated all the gear, tightened/loosened to extremes and I am still seeing the high leak rates, but not noticing anything during the night (been there / done that) and no leak complaints from the boss. Tried a backup FF mask (never wear it) and it leaked like a sieve which is why I don't wear them but couldn't sleep with the flutters, eye jet etc. so I know what a normal excess mask leak is. I can use the "mask adjustment" setting and get a frowny face when I know there is no leak beyond the mask ports. Checked the hose and connector for leaks but didn't find anything even with full blockage on the open end. After the first week or so I was getting smiley faces on the mask fit indicator in the morning but still seeing what are to me big numbers on ResScan.
I'm wondering if some sensor on the machine is bad or is it just overly sensitive maybe a different software process as compared to the PR and I've really been leaking badly for 5+ years(unlikely) considering my average AHI was 1.3 per Encore. Not sure I can trust the data on events if the leak rate is really so high and no reason at all for my mask to leak differently than before that I can tell, AirCurve is set to nasal mask and correct tubing type. I've even taken it off Auto and run it just at 16/20 which were my prior settings in the Sys1 trying to zero out any change but no change in leak rates reported...any thoughts or time to call the DME?
