Mask problems
Sore on Nose Bridge From CPAP Mask: Causes and Treatment
A red, painful or broken spot on the bridge of your nose usually comes from a nasal or full face mask pressing too hard on thin skin. The fix is to take the pressure off: loosen the straps with your provider's help, change the mask size or style, keep the area clean, and protect it. An open sore or any sign of infection needs a call to your doctor.
Signs
- Red patch on the bridge of the nose that does not fade by midday
- Tenderness or burning when the mask touches the area
- Skin that is peeling, blistered or broken
- A scab forming where the cushion sits
Common causes
- Pressure on thin skin
- The skin on the nose bridge sits close to bone with little padding, so pressure from a mask concentrates there. Published case reports describe the nasal bridge as a common site of mask related skin breakdown.
- Straps too tight
- Straps that are too tight compress small blood vessels in the skin, which can lead to irritation and breakdown, according to the Sleep Foundation.
- Wrong size or poor fit
- A cushion that rides too high or is too small for your nose pushes the frame into the bridge.
- Moisture or dryness
- Trapped moisture under the cushion can speed skin breakdown, while very dry skin can crack.
Fixes to try, easiest first
Take pressure off tonight
Loosen the headgear slightly and reseat the mask with the air on so it seals with less force. Check that the cushion is not sitting too high on your nose.
Keep the spot clean
Wash the area gently with mild soap and water at least once a day and pat it dry. Clean your cushion daily so oil and bacteria do not sit on the sore.
Ask before using creams
Ask your provider before putting a moisturizer or ointment on the area. The Sleep Foundation notes that extra moisture can worsen a wound and petroleum based products can damage mask materials.
Add a protective layer
A mask liner can add a soft barrier. Some people use a gel or foam nasal pad designed for CPAP masks on the bridge. Use only products meant for CPAP use.
Switch to a mask that avoids the bridge with your clinician
Nasal pillows and under-nose full face masks do not rest on the bridge at all. The Sleep Foundation notes nasal pillows can reduce pressure on the nose bridge. Your provider can fit one while the sore heals.
Get refitted for a new size with your clinician
If you need to stay with your current style, ask your equipment provider to check the size. A properly sized cushion often seals with much less strap tension.
Call your doctor or equipment provider if the redness will not go away, if there is an open sore where the mask sits, or if you see signs of infection such as spreading redness, warmth, pus, increasing pain or fever. Skin breakdown from a mask should be treated early, and it is a reason to change your mask rather than push through.

Frequently asked questions
Can I keep using CPAP with a sore on my nose?
Usually yes, but you need to take the pressure off the sore. A mask that avoids the bridge, such as nasal pillows or an under-nose full face mask, lets the skin heal while you keep treating your sleep apnea. Ask your provider for a temporary switch.
What can I put on a CPAP sore on my nose?
Keep it clean with mild soap and water and ask your provider before applying any cream. Petroleum based products can damage mask silicone, and too much moisture can slow healing. A CPAP nasal pad or liner can protect the area.
Why does my nose bridge hurt from my CPAP mask?
The skin there is thin and sits right on bone, so the mask's pressure concentrates on it. Tight straps, the wrong cushion size or a cushion sitting too high are the usual causes. Loosening and refitting often helps quickly.
