Learn how to troubleshoot and fix the most common technical problems associated with CPAP/BiLevel PAP sleep apnea devices

The success of your CPAP therapy depends on your CPAP/BiLevel PAP equipment working properly. If you’re having issues with your machine, be sure to check it at home right away and/or take it to your clinic so that you don’t have to sleep without it.

These are a few of the easiest and most effective solutions for common technical problems associated with sleep apnea devices.

Air blowing in your face

  • Possible solutions:
  • Tighten the straps evenly on your mask from one side to the next. 
  • If your mask has a swivel exhalation port, make sure it is turned away from your face. 
  • Check the mask or nasal pillows for obvious tears or holes. 
  • Pull the mask directly out/away from your face and then reposition, allowing the mask to create a new seal.
  • Check the connection of the tubing to the mask.
  • If applicable, lower or tighten the forehead adjustment on the top of the mask. This will distribute more pressure from the chin area to the bridge ofyour nose, preventing air from blowing in your eyes. 

A “whistle” noise from the mask

Possible solutions:

  • Be sure the exhalation ports are not partially blocked. 
  • If you are using a humidifier along with your CPAP/sleep disorder device, be sure there is no excess water accumulated in the tubing.

Condensation in your tubing or mask

Possible solutions:

  • Increase the temperature of your bedroom. 
  • Decrease the setting of the heater on your humidifier. 
  • Use a cloth wrap to insulate your tubing, or tuck the tubing under the covers with you.

These suggestions are designed to equalize the temperature difference between the room air and the air being warmed through your tubing; it’s the difference between the two that causes condensation.

Machine does not turn on. No air is coming out of the machine. Machine runs intermittently.

Possible solutions:

  • Be sure the power cord is firmly attached to the back of the machine as well as the wall outlet. 
  • Make sure the power cord is connected to an outlet that has power. You can verify this by plugging in another appliance to that outlet.

The air from the machine seems hotter than normal.

Possible solutions:

  • Check the filters. They may need to be cleaned in order to allow air to cool the unit. 
  • Be sure there is at least one foot of air space around the entire machine, and no vents are obstructed.

Some of these troubleshooting solutions will require a process of trial and error. If you need help with any of these tips, please contact your clinic or contact us. At Graymark, your sleep health is our number one concern.
