F20 Hydroplaning off your face at a 15 IP

Post by alancalan » Tue Oct 07, 2025 12:48 pm

I don't want to talk about apps, I just want to know if anybody has had trouble with the f20 masks not sticking to your face as there seems to be a hydroplane effect and higher pressures. Have those of you who are using the F20 found the pressure had to be lowered for the f20s to stay in place because the good seal will increase the pressure and you can find the connection them weaken and you get huge leaks. Is it only me?

The only way it would "hydroplane" is if your face was wet. If your humidity is too high your face could get wet at night causing "farting like" leaks. If it gets too wet, I guess the mask could move a little. 15 cm(H2O) is not an extremely high pressure.

Just curious, how fast does one need to go in order to get one's mask to hydroplane?

Conrad, when I find out, you'll be the first to know. And I am losing a decent amount of weight so the speed will be there to start the approach. I don't know why there is two of these threads going to identical.

But once again something is wrong. The other night I set the ramp for like 30 minutes and breathing was fine and then I think I dozed off and all of a sudden I felt the high pressure came in and the mask wouldn't stay on. However it did not fly off into the night it just lifts a little bit. It makes no sense because if the seal was good then the IP should have been lowered by the air curve 11, unless they were leak s in that pushed for more pressure and there comes the farty sounds and the lifting of the mass. The last couple of nights I had to use the p30i and the only problem with that is on the red meds report every morning I'm coming in at 10 points out of 20 or pretty significant leaks, So I am losing something.

Tightening up the straps of your mask doesn't help?

I had it at 5 with the P30i and when I tried the F20 I wrote it down to 3. Do some people have faces that don't fit the mold and cause problems. Do I have to shave every night before I go to sleep would that do the trick? Would using Vaseline help? When I put the pressure ramp to 30 minutes The breathing was fine and I don't know what happens after that 30 minutes cuz I think I might have been asleep by then. Once the rent period is over does it automatically go up to what pressure because My IP is set at 15. So I'm wondering does it kick into 15 and then see what happens and maybe once it does that it's too late.

Last time I used the p30i and on the ResMed daily screen I get one point out of 20 before the second test which is leaks. That's pathetic so I got an 81 for the evening everything else was the full five points. So nobody thinks I should try the F20 at lower settings? Wouldn't it be a good test? I go to my ENT doctor and ask who is also my sleep doctor but I think he's basically ENT and maybe they automatically get to call themselves sleep doctors. I just don't think they know anything and like I said the only thing they told me to do was put Vaseline but at that point I was only using the p30i.

With the p30i, I believe my issue is mouth breathing. I'm wearing that black chin strap which is very tight and I don't know how much tighter I could make it. The idea of using tape makes me sick. So it doesn't seem like there is any place to go with this as it all seems like everywhere brings dead ends. I even think the mouth breathing could affect the F20.

They tell you not to make it super tight But I did anyway cuz I looked at the top straps and they were just about as high as they could go and the bottom straps which have the push button crappy connection can only be made so tight or they pop off. I thought I saw someplace where there is a hook type setting so I'm going to go to Lincare Monday morning and maybe they'll have some ideas. They have pretty decent respiratory therapists there and like I said I can't go to my doctor It's useless. That's why the settings that I've been using for many many years came from this website.

I went back to the videos and I found one that I didn't see the other day and in that one it said to put the air fit F20 higher on the bridge of your nose so it's like right in the middle of your eye. That means the very inside bottom of the silicon mask itself was in the crease but leaning up to where my gums start. I think before that I was lower and I didn't hear or feel any leaks whatsoever. They were no farting type sounds and I didn't feel any pressure for a liftoff It's like it didn't exist with this mask.

I put in the information from Oscar but I don't know how to get it into the post thing. I press the icon that shows a picture but I think all it does is creates two bracketed ungs Image like that. So then how do I get the picture in?
..
So it looks like I was wearing the mask with the air curve 11 on a little less than 35 minutes. The first graph shows no large leaks, the second line CA Central apneas 18 little lines, OA obstructive apnea's six lines UA no lines h no lines.

Side banner

AHI shows 36.92

Large leak. 0

Clear airway 27.69 I don't even know what that means

Obstructive 9.23 oh and those two add up to the AHI so what is the clear airway

Unclassified apnea 0
Hypopnea. 0


Channel min. Statistics
Med. 95%. 99.5%
---------------------------------------------------------------------------------------------------
Pressure 11.00 13.86. 14.84 14.98
Epap. 9.86. 10.84. 10.98
Minute vent. 0.88 8.00. 13.19. 16.38
Resp rate. 0. 9.20. 16.00. 30.80
Flow Lim rate. 0. 0.00. 0.00. 0.02
Leak rate. 0.00. 0.00. 2.40. 7.86
Snore all zero
Insp Time 0. 1.58. 2.00. 2.00
Exp Time 0.26 3.38. 4.97. 5.38


AHI On the graph jumped but when I was taking off the mask I thought I should the air curve 11 off but obviously it wasn't but there is a line rising at a 45° angle then it goes straight and then all the way down That's probably one night shut it off.

Now I'm anxious to go to sleep and wake up and see what happens. No I did this with the silicon mask I don't know how it's going to be with the air fit the one that's got a clothy feel to it. For some reason I don't think it's going to be as tight but I have a bunch of them so I might as well try it.

I know that used to be a problem getting pictures in, is it still a problem, can we do it easily without going to an outside web site?

I'm not doing well with either the F20. By raising up the mask higher on the vision of my nose at eye height and I'm getting great marks on mess sale 19 of 20 and 20 of 20. I slept all night and I woke up at 7:30 and it said I slept 1:37 with 36 apnea events, most of them were centrals. And when I woke up the machine wasn't even on. How is that?

So then I switch to the p30i and I'm sleeping okay I'm getting much better numbers on AHI in the 2 or lower area put my math leaks I'm getting 10 of 20, 8 of 20, 11 of 20. And I'm feeling a little tired, but not terrible.

I was always a mouth breather, my whole life. I don't know where the leaks are coming from and it might not be the seal it might be that I'm breathing through my mouth even though I'm using a chin strap. I don't remember all these problems on the S9. Frustrating!

Chin straps don't stop you from mouth-breathing they stop the jaw from opening. You can breathe with your jaw closed.

Mouth-tape to stop mouth breathing with nasal masks,. Use straps or a cervical collar to stop the draw from dropping with FF masks.

Has nothing to do with the machine type, they both push air. One machine doesn't push air is such a way as to cause leaks.
