I have 32 teeth yep

Are they straight? Overcrowded? Have you had orthodontic appliances?

I will think about your CPAP problems to see if I can find some other good suggestions. There are some members who know a good bit about desensitizing one's self to the mask and process. Maybe some of them can chime in.

Yes straight. Done nothing to them

For the above post i will ask my doctor as i"m not allowed to change settings alone. Here are today results without mouthtaping : https://imgur.com/a/lJvluqw slept 45 min (15 min were trying to get to sleep) then 6-7h without. Doesnt seem to be a difference in the leak rate (first 15 min i werent sleepin) if i'm not mouth taping, the nose seem open too. Pressure around 7-8 whole 45 min too. is there anything abnormal? i don't know what obstruction level means too, if its about a clogged nose or something

Apparently, you don't feel like your nose is congested. I would really like to know what the obstruction level is reporting. Other data in your reports indicates you breathed steadily and easily.

Why did you remove the mask?

I remove the mask because it makes me very dizzy and a feeling that my head gonna "explode". I don't know if its the lack of pressure or something, but its a similar sensation to sleeping a very dry or humid room : displeasant. even after trying again wearing the mask, i fail to do so, because the head too "dizzy" from either low or high pressure or maybe the mask itself is way too tight in term of grip but the older one had similar rates so i don't know

Once i remove it, i can finally sleep "normally" as in 5 to 7h. Maybe my body isn't used to it ? but since it keep happening even after 7-8 days i'm doubtious.

The pressure was around 6-7 the whole night too not too low, even usually when i asked there and people told me 4 was too low because the cpap usually goes to 6 few min before i sleep and stay around 6-7

I'll suggest again that you try using the machine during the day or evening to get used to it. I'd be curious whether you'd get the dizziness feeling with day/evening use.

Ok i will try it for 1-2h. Wanted to menntion in case OSCAR doesn't show it, but the cpap comes with a humidifier, setting "3" with 250-300ml recommended to put daily so maybe it play a role?

Technically according to the latest 2 days, nothing should have woke me up right? It is true that when i put the mask at night, back of my head and the plastic around nose "hurts" for a bit as if it was uncomfortable so maybe that is one of the reason. I will try to tire myself today and wear it lightly and see how it works out, as long i can sleep with it (will do the max pressure leak test before btw)

Find that mask model on youtube and watch a couple of videos about fitting and adjusting. Masks should not be adjusted tightly.

Hello

I tried the CPAP machine while awake for a good 1h30 yesterday and some things i noted:

Pressure goes to 6 after 20 min then 8 and stay there. Its actually easier to breathe at 6-8 than at 4 and i didn't notice leaks. I didn't felt dizzy or anything at all, definitively not the same sensation as i wake up super tired and feeling something "stuck" in my face, went through the same grip while sleeping


Here are the results: https://imgur.com/a/YsOLeUH

Slept almost 1h then woke up removed the mask (despite being way more tired than usual), went back to sleep and got 7h10. The pressure seems kind of low but i woke up at 6-7 pressure so i don't know


I thought i got woken up by an apnea/mouthleak because of not enough sealing/pressure but it doesn't seem to be the case so i don't know why my body randomly wake up and want me to remove the mask as if it was too "heavy" (thats the word) on my face


Btw one of my older night, i tried to back sleep (something i never did) and i got an abnormal high AHI only slept 13 min before getting a paralysis, would it be caused by positional apnea? https://imgur.com/a/vNHPmMK

Interesting! Your body needs to learn some new habits, and if you keep using the machine during the day or evening, you'll help it a lot. So keep doing that. I have the suspicion that if you keep at it, you'll stop feeling those sensations of dizziness and pressure.

Yes, lots of people breathe easier at pressures higher than 4. Remind me why you can't just raise your minimum to 6, where you're more comfortable?

I'm not able to rn i need to ask during the appointement, but beside this i don't know what could cause a wake up anywhere between 40-60 min? It doesn't correlate to the end of a sleep cycle or external noise/need to pee since no matter at which hour i sleep, 60 min is around max with CPAP

The pressure needed while sleeping and being awake is different right? Because when asleep it rarely goes over 6 but awake it went 6 after 10 min, 8 after 20 min and for the remaining hour i could use my phone pretty easily without feeling "short of breath". the "dizziness" sensation doesn't exist too

The machine algorithm that controls the pressure is designed to interpret sleep-breathing. Awake-breathing is different from sleep-breathing. The machine algorithm doesn't know what to do with awake-breaking.

I suggested raising your minimum pressure just to be sure you're doing everything that could help you be more comfortable at night. Are you unable to change the pressure because of a rule? Or some other reason? Do keep using the machine during the day/evening. It's quite likely this will help you reach the point when you can just roll over and go back to sleep when you wake up -- with your mask on.

Good morning

Just tested the minimum 6cm pressure setting and the graphic looks much better: 6 rera only, no hypopnea/apnea!

Here are the results: https://imgur.com/a/g6emX8X

Slept from 2h50 to 3h30 (first part was testing don't take it in account), woke up for 1 min for some reason and went back to sleep, slept untill 4h then removed the mask and slept 7h

The increased pressure seems to eliminate hypopnea/osa altough add 1-2 more rera. Had one critical leak that didn't wake me up or disturb the curve much but i'm still having the 1h max problem ...

I will try to record myself to see if it might be possible that i start back sleeping causing me to wake up, i can't think of another reason at this point

Encouraging numbers, and I'm glad you were able to go back to sleep after your short wake-up. Now you just need to work on increasing the total time you use the machine. I know I sound like a broken record, but keep practicing during the day/evening!

https://imgur.com/a/tpOQA0t Today results. 4h to 4h35 and 4h40 to 5h, then 1h with mask on (no cpap) and 4h without

Welp, the usual. The flow rate looks normal, no mask leak so i assume i'm not mouth breathing but i'm still not didnt found the awakening cause as there doesnt seem to be an event/increased pressure causing it? Obstruction level chart seem high but i'm not finding any info about it on the net. I will try to record more on camera, btw the mask seem a bit bit "tight" around the nostril, like when i put it, it pressure my 2 nostril so maybe M Size is too small and "congest" my nostril making me waking up but then again L Size from their paper chart fit too big while M is a "perfect fit"

Something interestibg is that after i turned off the machine, i kept my mask on for the first time because i was too tired around on camera. I woke up 1h after which i haven't done in a while without the mask. The cause? Mouth breathing. 20 min before i woke up while having the mask on, i had my mouth open all the time and woke up with seemingly a bad headache. then i removed it and slept 5h

Maybe this could mean that the mask is restricting my nostril as i don't seem to mouth breath outside? Or just general mouthbreathing, but then again i can sleep 5-7h straight without mask and 1h only with it (cpap on or off)

Please do not sleep with the mask on your face and the machine off. It's bad for your health.
