Issue Why It Happened What To Do
Excessive Warm Air Out of
Mask
The air out of the mask is
much warmer than usual.
The air lter may be dirty. Or,
the device may be operating
in direct sunlight or near a
heater.
Clean or replace the air lter as
described in Chapter 7.
The temperature of the air
may vary based on the room
temperature. Make sure the
device is properly ventilated.
Keep it away from bedding or
curtains that could block the
ow of air around the device.
Make sure it is away from direct
sunlight and heating equipment.
Ensure the cooling air vents
are not blocked. If the problem
continues, contact an authorized
service representative or Philips
Respironics to have the device
serviced. Please have the model
number and serial number ready
when you call.
Mask Discomfort
The mask feels
uncomfortable to wear, there
is signicant air leakage
around the mask, or the
patient experiences other
mask-related issues.
This could be due to
improper headgear
adjustment or improper mask
tting.
Make sure the patient is properly
tted with the correct size mask.
If the problem continues, try
tting the patient with a dierent
mask.
Runny Nose
The patient has a runny nose.
This may be caused by a nasal
reaction to the airow. This
only applies to non-invasive
therapy and will not occur
during invasive therapy.
Call the patient’s health care
professional.
