A leaky CPAP mask is one of the more common frustrations people can experience during CPAP therapy. You may notice the air blowing into your eyes, or hear a hissing sound during the nite or wake up to find your mask has moved.
The good news is that most CPAP mask leaks are caused by relatively simple things.
Understanding the reasons behind your CPAP mask leakage can guide you on what adjustments to make and when to consider replacing your mask or its components.
What Causes CPAP Mask Leakage?
If a CPAP mask is not sealing against your face all the time, it can leak.
This can happen if the mask is not fitted properly, has moved in your sleep, is not adjusted properly or has parts that have worn.
A small amount of intentional airflow is normal. CPAP masks are designed with vents to allow exhaled air to escape. The problem is unwanted leakage around the seal of the mask.
How Do I Know if My CPAP Mask is Too Loose?
Maybe.
If the mask is too loose, the seal can be broken during sleep by movement allowing therapy air to escape.
Tighten your mask so it fits comfortably and snugly over your head.
But don’t tighten all the straps down all the way right away. A CPAP mask should not be painfully tight.
In fact, overtightening can sometimes distort the mask cushion and make leaking worse.
Yes. One of the critical factors in achieving a good, reliable CPAP mask seal is proper sizing.
If your mask is too big it will move around on your face and if it is too small it will sit wrong and be uncomfortable.
If you find yourself playing with your mask to try to stop the leak, check to see if you have the right size.
Different CPAP masks fit differently too, so just because you're one size in your current mask doesn't mean every other mask will fit exactly the same.
What causes my CPAP mask to leak while sleeping?
Your mask can be affected by how you sleep.
For example, if you sleep on your side, part of your sleep apnoea mask could be pressed against your pillow. This can dislodge the cushion and break the seal temporarily.
Movement during sleep can also cause the mask or headgear to move.
Try fitting and adjusting your mask when lying in your normal sleeping position instead of only adjusting it when sitting or standing.
Some users find CPAP-friendly pillows useful in reducing contact between their pillow and mask.
Can an Old CPAP Mask Cause Leaks in Air?
Yes."
CPAP mask parts aren’t meant to last forever. Nasal pillows, cushions and headgear wear out with regular use over time.
The cushion is worn and may not seal as well as it did new. And, headgear can stretch over time, making it harder to keep your mask in the right position.
Check your equipment regularly for obvious signs of wear, damage or deterioration and adhere to the manufacturer’s recommendations for replacement.
Will Cleaning Your CPAP Mask Help Prevent Leaks?
Keeping the mask clean can help maintain the seal and cushion.
The mask cushion may accumulate natural oils from your skin. Regularly clean your equipment in accordance with the manufacturer’s instructions to keep it in good condition.
Don't use cleaning chemicals or methods that are not approved as they may damage the mask material.
What if Air Leaks Out Of My Mouth?
If you use a nasal mask or nasal pillow mask, sleeping with your mouth open can let therapy air escape.
This is different than air escaping around the mask cushion.
If you’re experiencing regular mouth leaks, talk to your CPAP provider. Depending on your situation they may suggest looking at other solutions including whether a full face mask may be more appropriate.
When to Replace Your CPAP Mask
Check the fit, clean your mask, adjust your headgear and if you still have significant leaks, check your mask and its components for wear.
Sometimes you only need to replace the cushion or headgear, not the entire mask.
When you are looking at CPAP masks for sale be sure that the mask will fit your therapy needs and that you choose the right size and style.
CPAP masks in Australia come in a variety of styles including full face, nasal and nasal pillow styles.
How to Fix a Leaking CPAP Mask the Easy Way?
Start with the basics: Check your mask position, check the cushion, adjust the headgear and make sure you are using the correct size.
Then, try the mask on with your CPAP machine turned on, in your normal sleeping position.
