[CPAP] Need help trying to understand where the air leak is coming from.
#1
Hi everyone.

I'm using a ResMed S9 AutoSet machine without a humidifier, since the day i've been using it, i'm facing air leak problem but i can't understand anything from the summary via ResScan. Will really appreciate if anyone can help & guide me with understanding my summary and the graphs on ResScan.

Here's the summary shown on my ResScan,
   

Regards.

Anon, mask up and turn the system on, then feel and listen for leaks at the machine in the humidifier area, at the hose connection, along the hose and near the mask connection. Also check that the nasal cushions are fitted over the frame ring and the fine diffuser holes are not damaged. It looks like leaks might be high from the data, but inspecting the machine, hose and mask is the best bet.

Thanks for the reply sleeprider, I don't use a humidifier also I've checked everything every night before i sleep to ensure that there's no leak. But every morning when i wake up from my sleep and check the mask fit status, it's always showing a red face.
My sleeping partner told me, at times she can hear some air leaking from the mask but no matter how tight i strap the mask, it still shows that the mask isn't fitting well. So i wish to find out if it is due to the mask or is it because the air is leaking out from my mouth.

Have you verified that your S9 is set to "Nasal" and not "Pillows" or "Nasal Ultra"?

Yes, sgearhart. It's set to Nasal.

The only other thing I can think of is there is no one mask that fits everybody's anatomy. You might start pondering the idea of trying a different mask. With eleventy-million masks of the same type (FFM, Nasal, Pillow) there is a high probably that one fits your face better than the others.

When i started using this CPAP machine 2/3 months back, the first few days everything was fine. The mask fitted well and the leaks wasn't this much but as time goes by, the leakage shoots up and i have never seen "Green" on my mask status.

Is there any way i can verify if the leakage was coming from the mask or my mouth?

The only ideas that come to mind are:
1. Try taping your mouth shut when you go to sleep. Then look at your data the next morning.
2. With the mask in place and under pressure, dribble some water with a little soap added around the mask and look for bubbles or a sound change.
3. Don't do 1 and 2 at the same time!

This might be a clue. Have you changed the nasal pilllows in that time? They are perishable.

I'll try both methods and see what's the results. Instead of taping i'll pick up a chin strap i guess.
Thank you for the ideas and replies. Appreciate them alot.

sleeprider, nope. I've been using the same nasal mask while i was trialling the CPAP Machine and right now when i purchased one and use it.
