Problems with CPAP or BiPAP

The most common problems are:

  • Mouth air leaks:

    • Dry mouth is the main symptom
    • Causes poor sleep quality, morning tiredness
    • Difficult to treat, treatments are:
      Full face masks, chin straps, or lowering the pressure
  • Mask discomfort:

    • Any discomfort will wake you up!
    • Try to make the mask comfortable with adequate air seal before you fall asleep
    • May need to exchange your mask
  • Claustrophobia:

    • Certain masks cause less claustrophobia, i.e nasal pillows
    • Ask your doctor or the sleep center regarding CPAP desensitization
  • Excessive pressure or difficulty exhaling:

    • Your doctor may temporarily lower the pressure to make it more tolerable. This may be increased later.
    • Certain machines have a pressure release technology to make it more comfortable.
    • BiPAP machines lower pressures for easier exhalation. They require your insurance's approval. But, these machines may be louder, heavier, or more expensive.
  • Water condensation inside the CPAP tubing:

  • This is a winter's problem, it should resolve when the room temperature gets warmer in spring and summer.
  • Use an insulation or a cover for the CPAP tubing.
  • Decrease the temperature of the heated humidifier.
  • Put the machine at a lower level than the bed.
                       Water should drain back to the humidifier chamber.
  • Use a longer hose and leave it next to your body. Your body will keep the tube warm.
