  Molly Wilkinson DDSAug 18, 2025
  If you're experiencing a dry mouth and throat while using 3B Medical Equipment, it's likely because you're sleeping with your mouth open. The pressurized air escapes through your mouth, leading to dryness. To address this, consider using a chin strap to keep your mouth closed during sleep or switch to a full-face mask. For more detailed advice, it's best to contact your physician.

  If you're experiencing eye irritation with your 3B Medical Equipment, it could be due to an improper mask fit or incorrect positioning, leading to air leakage. Try narrowing the distance between the forehead support and your forehead, but be careful not to overtighten the mask to avoid facial markings. You might also want to add extra filling to ensure a better seal. If the issue persists, consider contacting your equipment supplier to explore alternative mask options or add more filling.

  If you notice facial reddening while using your 3B Medical Equipment, it could be due to several reasons related to mask fit. First, try loosening the headgear, as the mask may be too tight. Also, adjust the distance between the forehead support and your forehead, experimenting with different positions since the angle and size vary by mask type. Finally, ensure you're using the correct mask size; if not, contact your equipment supplier to get the right one.

How to prevent water in the mask with 3B Medical Equipment?
- A
  Angela FisherAug 26, 2025
  If you find water in your mask while using your 3B Medical Equipment, it's likely due to condensation of humidified air in the tube and mask when the room temperature is low. To resolve this, try turning down the humidity setting or raising the room temperature. You can also place the tube under your quilt, use a tube cover, or hang the tube loosely, ensuring the lowest part is below your head.

Why do I have a cold or runny nose using 3B Medical Equipment?

  Ryan LawrenceAug 28, 2025
  If you are experiencing a dry, cold, runny, or blocked nose, or feel like you're catching a cold while using your 3B Medical Equipment, it's likely a reaction to the airflow and cold air. The fast airflow can cause the air to become cold, irritating the nasal mucosa, leading to dryness and swelling. To alleviate this, increase the humidity setting on your device. Additionally, it's advisable to contact your physician, but continue the treatment unless they advise otherwise.

  If your 3B Medical Equipment isn't turning on, there are a few things to check: * If the Auto On/Off feature is enabled, try taking a few deep breaths with the mask on to automatically start the device. * Ensure the power cord, adapter, and device are properly connected. * Verify there's no power outage by testing a light or other device. If you suspect a blown fuse, contact your equipment supplier for assistance.

Why am I uncomfortable with the pressure on my 3B Medical Equipment?
- J
  Joshua WhiteSep 2, 2025
  If you feel discomfort adapting to the treatment pressure with your 3B Medical Equipment, it's likely because the pressure is higher than 13 cmH2O. While this pressure is set according to your specific needs and shouldn't be lowered too much to effectively treat sleep apnea, it typically takes up to four weeks to adjust to pressurized air. Try to relax and breathe through your nose. If the problem persists, consult your physician.

Why is my 3B Medical Equipment producing very low pressure?
- S
  simonjeffreySep 4, 2025
  If your 3B Medical Equipment is producing very low pressures, it could be due to a few reasons. First, check if the air inlet is blocked and replace the air filter, ensuring the inlet is clear. Another possibility is that the treatment pressure has been accidentally changed, in which case you should contact your physician. Lastly, if the Ramp feature is enabled, remember that it takes time for the pressure to reach the set level; if needed, disable the Ramp feature or shorten the ramp time.

Why are my sleep apnea symptoms recurring with 3B Medical Equipment?
- J
  James WatersSep 7, 2025
  If your obstructive sleep apnea symptoms return while using 3B Medical Equipment, it's possibly because you're sleeping with your mouth open, causing pressurized air to escape and leading to respiratory tract blockage. To address this, consider using a chin strap to keep your mouth closed during sleep, or switch to a full-face mask. For further guidance, contact your physician.

- J
  Jason RoweSep 9, 2025
  If your 3B Medical Equipment is running but the pressure inside the mask doesn't match the set treatment pressure, start by checking that the tube is properly connected. If the issue continues, there might be holes in the mask or pressure sensing tube, in that case contact your equipment supplier. It's also possible the device itself is faulty, so contact your equipment supplier.
