I found the summary for leaks. It gives the maximum, minimum and average for leaks, but it provides it for a week at a time (this report does NOT list a day at time in the summary).
I'm looking at the last week of the report:
Maximum Leak: 156.9
Minimum Leak: 35.1
Average: 39.57
So, what you've said about a possible large leak messing things up -- seems like that might be applicable here.
I'm just wondering though -- I know that sometimes when I move/turn over at night, I can hear a HUGE leak, but I immediately fix by adjusting the mask (I do this a lot during the night). Would the ventilator pick that up, thus showing a HUGE leak, even though it wasn't very long? Because my averages are pretty much in the 30's no matter what the maximum got to.
Interesting.
Many people do NOT realize that large spikes are hidden in the "average numbers" reported. Which is why a graph is the preferred method.
I cut my baby teeth on FP 431 - It took me a whole year of messing around before I realized that my pressure was chasing the leaks and the higher the pressure went the more leaks I had.
1 Year. Most of that time was because I had NO DATA - Only a Plus machine and Apria.
While I found the FP 431 to be a very comfortable mask - many people posting here had problems with leaks just like I did.
Switching from 431 to the 432 - Many of the RT's do NOT realize that you will need the next size larger when going to the 432 because the foam filler takes up some space inside this mask. Example - I took a Large 431 but needed an XL 432. Yes, removing the foam may give one some needed space IF the mask is sized wrong.
At a CPAP pressure of 17cm I learned that it was almost impossible to seal the FP 431. One thing I did which helped immensely was to take one finger and press (just lightly) on the elbow (swivel) where the hose connects to the mask. That is the point (under the elbow) where I tied a knee-high nylon around my head to keep the mask from moving away from my face.
NO additional pressure forcing the mask in on my face. Just something to keep the mask from moving out and away from my face when the pressure ramped UP.
I also felt the headgear that came with my 431 stretched more and more even before I woke up - because when I woke up it fit differently. So I change it with the UMFF mask headgear but any Resmed headgear would probably be an improvement.
Worth noting - the 431/2 has a chin cup. When donning this mask the chin should be place into the chin cup first then the mask gently brought up to the face while pulling the headgear up and over the head. I know - I know. But it is the best fit.
I should also note here something I didn't know right off. The 431 comes with 3 different sizes - S, M, & L. This makes it easy to get the right fit. The size is noted on the bottom of the chin cup. The 432 ONLY comes with one size.
I finally got on track to feeling better when I got the software to go with my Respironics Auto and then switched to nasal pillows - the Aeiomed Headrest.
It was a rough ride - just ask my DME
