This month CPAP Expert Carol will be tackling your questions on how to troubleshoot common CPAP mask problems.

Question: “I have been using a CPAP machine for a year now. The first six months were great but the last six months I’ve . been waking up with bags under my eyes. My doctor has no answer. Hoping you might have an idea what to do. I use the CPAP pillow, full face mask, and am a side sleeper.”

Answer: I am sorry to hear that! There could be a couple of reasons that you see bags under your eyes. First, Have you changed your mask cushion within the last three months or your mask within the previous six months? It may be that you have a mask leak, which has been known to cause bags.

Second, It could also be that the mask/headgear that you are using is too tight. If too large and you have to pull the headgear too tight to avoid leaks, this may be the cause. Also, please keep in mind that bags under your eyes could be occurring naturally and not related to your CPAP Therapy at all. 

Question: My son started using his CPAP three weeks ago. He takes his mask off and doesn’t remember doing it. Do you have any suggestions to help? Is it unusual that he is removing the mask after three weeks? How long does it normally take before this passes?

Answer: Thank you for reaching out. I am so sorry that your son is having trouble keeping his mask on. It is relatively common for new CPAP users to remove their mask during the night unintentionally. Unfortunately,  there is no specific time frame we can give to can say that it will pass. However, I do have a few suggestions!

For starters, ensure your son is using the correct size mask; if not, he will have a difficult time getting used to it. I also would recommend having him try different masks to see what feels the most comfortable. Be sure to stop by the Store if you are in the area to try a few on!

Some CPAP users find wearing a chin strap in conjunction with their mask to keep then from easily removing the mask at night. Another option is to try adding tape to the headgear, in areas that will not affect his CPAP therapy, some people have even opted to apply band-aids on the mask strategically and find that helps.

Lastly, he can try wearing the mask while he’s watching television, playing a video game, surfing the internet, or just relaxing. This will encourage him to get used to wearing the mask in general.

Question: Is it common to get eye infections from CPAP use?

Answer: I can’t say for sure that there is a direct correlation between eye infections and CPAP use. However, it may be air from your mask blowing into your eyes that is causing the irritation, if that sounds like it could be the case then you probably have a mask leak. Mask leaks are 100% preventable and easy to fix. I would recommend reading through this article the dives into the possible causes of masks leaks to help you determine the source.

Question: Lately, when I exhale the little flipper on my full face mask sounds like a loud heartbeat, making it impossible to fall asleep. I have used this machine and mask for about four years and have never experienced this before. My supplier is telling me all full face masks have a flipper and nothing can be done. What do you suggest?

Answer: I am very sorry that you are having that issue with your mask. My first suggestion is to check the bottom of your mask to ensure that the ports are completely pushed in—sometimes those can come loose.  Alternatively, a part may be out of place on your mask, and that may be causing the noise. If that is the case, I recommend checking out the video below which features a step by step reassembly of your CPAP mask:

    Hello; I’ve had my cpap machine now for almost 2-weeks. I’m definitely getting more sleep, which is great! However, I’m on my 2nd mask due to irritation on and around my nose.

    I got a mask fitting at my local sleep clinic and found that the nasal pillow was my most comfy option. However, I was fitted in a recliner, not a bed. I’m a side-sleeper, have been all my life. The N30i by ResMed was the best option because it allowed me to sleep on my side without obstruction the mask due to its design. The hose on top was also ideal because I tend to turnover to get comfy.

    After first 5 nights, I was losing more than 24/L of airflow each night which has been the basis of my point loss so far. Also, I realized the N30i had thick plastic connectors by my nose which dig into my cheeks and bridge as I slept.

    So I bought the P30i and have used that last 6-7 nights. It seems to be a bit better, less mask off instances, but now, my nose is suddenly breaking out, the inside and outside edges of nostrils are raw and hurt throughout the day because of it. I’ve not returned the N30i until I know this P30i one works…but little bumps around my nose and raw, scabby irritation is now even more disruptive to my sleep and during the day.

    My score is averaging 90 and majority of point loss is from adjust and mask off. I’m getting 7+ hours of sleep, my events are down from 8.2 baseline to under 2 consistently. What masks will benefit my sleep habits and not cause irritation. I’m confident the sizes are right but I’m open to suggestions.
