Knights to the Rescue Troubleshooting Guide: An Odyssey

Never fear, your valiant Knight is here.

I get water in my tubing. It feels like i am sleeping in a moat.

Water collecting in the tubing is a common problem. It is caused by condensation, a result of the air flowing in the tube being warmer than the air temperature of the room. There is an easy fix to this problem:

·       You can simply lower the temperature of your humidifier

·       You can also try insulating your tubing with one of our tubing wraps or switching to heated tubing (tubing wraps are not covered by most insurance but heated tubing is).

Recommendation: First, turn your humidifier down one degree. If that makes you too dry, insulate the tubing or ask our Knights for heated tubing.


The loud noise you’re hearing could be either the cushion or pillows of your mask beginning to wear out, or because your mask doesn't fit properly. This noise is caused by a leak in the seal, allowing air to escape between the mask and your skin. To fix this problem:

  • Try another mask. Check out our Mask Trial Program!

Recommendation: Replace your nasal cushion every two weeks and your full face cushion once a month. Replace the whole mask every 90 days.

My mask won't stay in Place or Doesn't fit like it used to.

Masks and headgear stretch out over time causing the mask and straps to slip, leading to shifting and rubbing. This can cause skin irritations, forcing the wearer to pull the headgear too tight to maintain a good seal. This can lead to skin sores or indentations. We can fix that:

  • Replace your mask and headgear at the recommended frequency by signing up here, for our Automatic Resupply Program, and you’ll never have to think about replacing your equipment again!
    • Most insurance allows replacement every 6 months

Recommendation: Replace your cushions every 2 weeks (nasal) or monthly (full face) and the entire mask every 90 days.

It is our quest to figure this out,

  • You may be a mouth breather using a nasal style mask, while a full face mask is more suitable. Our trusty Knights can adjust the comfort features (Cflex, Biflex, EPR, or Sense Awake) on your machine
  • It could also be that you should be using a BiPAP machine instead of a CPAP machine. Talk to one of our Knights if you have questions.
  • You may be suffering from having an ill-fitting mask, this can be fixed by replacing or re-fitting you with a new mask
  • The ramp feature on your machine may need to be adjusted or turned off

Recommendation: raise your humidifier one degree. If the problem persists, call one of our Knights. They can help you determine if you need some changes made to your machine.

I WAKE UP REGULARLY WITH A DRY MOUTH OR THROAT, like a fire-breathing dragon.

Here are some tips to cure your dragon mouth,

  • You may need to increase your humidity by turning up the heat setting on the humidifier
    • The higher the heat, the more moisture you will get
  • Heated tubing would also give you better control of the humidity
  • Add an additional humidifier to your room
  • You may be a mouth breather and a full faced mask would be more suitable for you

Recommendation: Turn up that humidity.

Wearing the mask makes me feel CLAUSTROPHOBIC, like i am trapped in a dungeon.

It is normal for patients to feel some anxiety when first wearing a PAP device, the easiest fixes to this problem are:

  • Taking time to adjust to your machine, by wearing it when you are reading or watching TV before committing to wearing it an entire night
  • Being flexible to what style of mask you wear, it is common that those who feel claustrophobic are most comfortable with full faced masks
    • For more information about our Mask Trial Porgram, contact us

Recommendation: Stick it out! There is light at the end of the tunnel.

I WAKE UP WITH my helmet feeling two sizes too small causing SINUS PRESSURE OR CONGESTION.

This is usually fixed by trial and error from the following suggestions:

  • Adjust the temperature of the humidifier
  • Eliminate the humidifier all together
  • Add heated tubing
  • Switch from a CPAP machine to a BiPAP machine

Recommendation: First, adjust your humidity settings up or down until you find the most comfortable setting. If that doesn’t help, call on one of our Knights. We will get you through this.

MY MASK IS CAUSING IRRITATION OR SORES, like a chainmail under my armor.

good knight liftIt is not uncommon to experience some irritation initially, especially around the nostrils if using the nasal pillow system. Irritation is usually mild and doesn’t take very long to go away.

  • Try using a water based-lubricant like KY Jelly as a barrier between your skin and the cushion or pillows
    •  We do NOT suggest using Vaseline or other greasy petroleum-based items. Water-based lubricants are more natural, safer and better moisturizers
  • If you were not experiencing irritation before from your mask and after a few months you suddenly were, then you simply need to change your mask pillows or cushion
    • The problem is oil often build ups on the the headgear. If you are not cleaning your cushion daily then the oil from your skin will build up on the cushion, causing breakouts
  • For severe or persistent irritation, it may be the mask size or style and you may need to be refitted
  • If the irritation on your skin is an actual sore or a breakdown of the skin, it is recommended that you stop using the mask until you can be evaluated by a Knight and fitted into a different size or style

Recommendation: Change out your cushions every 2 weeks or once a month, depending on the sort of mask you have. Adjustments can also be made by lubricating the cushions with a water-based lubricant, or fitting the cushions with a cloth barrier. This is only a minor hiccup on your quest to sleep freedom.


  • This is as normal as a Knight slaying a dragon. It especially occurs if you tend to roll around a lot in your sleep. We suggest making sure you have a good fitting mask. You could also try adding a heated humidifier or even a chin strap.


  • Try focusing on your breathing while wearing your CPAP mask before bed.
  • Take advantage of your ramp feature which provides automatic, gradual increase in air pressure while you sleep. Make sure you get in the habit of a regular night time routine.

  • Your problem could come from your mask not being the correct fit. Our Knights will work with you to find the perfect fit!
