What to do if I have eye irritation using BMC Medical Equipment?

  Crystal CraneAug 10, 2025
  Eye irritation with BMC Medical Equipment can occur if the mask doesn't fit well, leading to air leaks. Try narrowing the distance between the forehead support and your forehead, but be careful not to overtighten it. You can also add filling to the mask to prevent leaks. If the mask cushion hardens, replace it. If problems persist, contact your equipment supplier for a more suitable mask.

Why do I have a dry mouth and throat using BMC Medical Equipment?

  Paul MartinAug 18, 2025
  If you experience a dry mouth and throat while using BMC Medical Equipment, it's likely because you're sleeping with your mouth open, causing air to escape and leading to dryness. Consider using a chin strap to keep your mouth closed during sleep, or switch to a full-face mask. Contact your physician for more advice.

How to fix facial reddening caused by BMC Medical Equipment?
- A
  Anthony MaloneAug 25, 2025
  If you're experiencing facial reddening with your BMC Medical Equipment, it could be due to several reasons related to the mask fit. First, try loosening the headgear, because the mask might be too tight. Also, adjust the distance between the forehead support and your forehead, trying different settings, as the angle and size vary by mask type. If neither of these adjustments helps, the mask size may be incorrect; contact your equipment supplier for the right size.

What to do if I have a cold using BMC Medical Equipment?
- C
  Cheyenne HillSep 2, 2025
  If you have a dry, cold, runny, or blocked nose, or are experiencing a cold while using BMC Medical Equipment, it may be 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. Try increasing the humidity setting of the humidifier. Also, consult your physician and continue any prescribed treatment unless they advise otherwise.
