22.1 Common Problems in Patients and Corresponding
Solutions
Problem
Possible Cause
Solution(s)
Dry, cold, runny,
and
blocked
nose; having a
cold
The nose reacts to the
airflow and cold. Due to
fast airflow, the air
becomes cold, leading to
nasal mucosa irritation and
subsequent dryness and
swelling
Increase the humidity setting of
the device.
Contact your physician, and
continue treatment unless the
physician suggests the opposite
Dry mouth and
throat
Probably because the
patient sleeps with his or
her mouth open, and the
pressurized air goes out via
the mouth, leading to nasal
and throat dryness
Use a chin strap to prevent the
mouth from opening during
sleep, or use a full-face mask.
Contact your physician for
details
Eye irritation
The mask size or model may
not be correct, or the mask
is not positioned correctly,
thereby leading to air
leakage
Narrow the distance between
the forehead support of the
mask and the forehead. Note
that adjusting the mask too
tight may leave markings on
the patient’s face.
Add additional filling to the
mask so it does not leak.
Contact your equipment
supplier for an appropriate
mask. Add additional filling to
the mask if necessary
Mask cushion (the soft part
of the mask) hardens
Replace the mask or mask
cushion
Facial
reddening
The mask is too tight
Loosen the headgear
The distance between the
forehead support of the
mask and the forehead is
not correct
Try a different distance. The
angle and size of the forehead
support differ according to the
type of masks
Wrong mask size
Contract your equipment
supplier for a correct-size mask
