Nasal Mask and pressure
I am trying a nasal pillow mask. If I start mouth breathing will it show up as a leak? Thanks Diane

most likely. I am just guessing here but I would think that a part of that would depend on how long you are mouth breathing (or that your mouth is open); if it isn't but a quick sec or there is some small leaking from the corner of your mouth and isn't long, it may not show up as a leak.

I know I was using the blower to dry my hose and it took a little while before the high leak alarm went off. I am sure others will have more info for you.

RE: Nasal Mask and pressure
Whether or not is shows as a leak, the real problem will be air rushing out your mouth instead of into your lungs. If you think an open mouth is going to be a problem, buy a chin strap to keep your mouth closed.

Hi Diane,
If you think you are going to breathe from your mouth, you could try a chinstrap to see if that helps you.
Good luck to you.

RE: Nasal Mask and pressure
Tried a chin strap it was a no go. Using the nasal mask I woke with dry mouth. Changed to ffm same dry mouth even with wet mask in the morning. Will my AHI reading be correct with nasal mask if I open my mouth? I have no way of knowing how long mouth is open.

It might be helpful to distinguish between mouth-breathing and mouth-leaking. Mouth-breathing can occur when your nose is plugged up with congestion. If this happens while wearing a nasal mask the flow rate will drop to essentially zero because no air is moving through the CPAP hose. That's not going to show up as a leak.

On the other hand, mouth-leaking is something that occurs when you're wearing a nasal mask, your mouth drops open, and the pressurized CPAP air comes hissing out of your mouth. This will show up as a leak because lots of air will be flowing through the CPAP hose.

The CPAP machine has two sensors that it uses to draw all of its conclusions: a flow rate meter and a pressure sensor. When the flow rate meter is spinning it means air is traveling through the CPAP hose. The rate at which it spins is used to determine the flow rate, and when the flow rate is too high it concludes that you have a leak.

I'm sorry you're having this problem. Some people have recommended a product called biotene mouth wash to help with the dry mouth. Most of these issues that we experience with CPAP therapy are temporary, and they go away as our bodies adjust to the therapy.

To answer your question, the CPAP machine can't really determine the AHI accurately when the leak rate is too high. It doesn't matter though, because if the leak rate is too high the CPAP can't maintain the pressure splint and your airway collapses as if the CPAP machine isn't even there.

Getting your leak rate under control is first and foremost when it comes to CPAP therapy. If your leak rate is not under control, then nothing else matters.

Dry mouth is from mouth breathing, You,ll experience dry mouth somewhat using full face mask. what do you mean "even with wet mask" ... rainout or some moisture from your breath

Leak number include mask leak and mouth leak. The number you see on the screen is the 95th percentile which means leak was at or below this number for 95% of the time using the machine so you need to check the detailed data for a better picture of whats gong on. Good mask fit indicate 70th percentile leak was less than 24 L/m but any leak small or large if interfere with your sleep must be addressed
