Problem Possible Cause Solution (s)
Facial reddening
Wrong mask size.
Contract your equipment supplier
for a correct-size mask.
The patient is allergic to the
materials of the mask.
Contact your physician and
equipment supplier.
Use a mask which is not made of
natural rubber latex.
Place a lining between the skin and
mask.
Water in mask
When the humidifier is used,
the humidified air tends to
condense in the cold tubing
and mask if the room
temperature is low.
Turn the humidity setting down, or
raise the room temperature.
Place the tubing under the quilt, or
use the tubing cover.
Hang the tubing loosely, and make
sure that the lowest part of the
tubing should be lower than the
patient's head.
Nasal, sinus, or
ear pain
Sinus or middle ear
inflammation.
Contact your physician
immediately.
Discomfort due to
inability to adapt
to the treatment
pressure
The patient will feel
uncomfortable when the
treatment pressure is higher
than 13 hPa. However, the
treatment pressure is
determined by the patient's
conditions, and the device will
not be able to treat sleep
apnea if the treatment
pressure is set too low.
It takes a maximum of four weeks
for the patient to adapt to
pressurized air.
Relax and breathe through the
nose. If the problem still exists,
contact your physician.
Obstructive sleep
apnea symptoms
recur
It may be because the patient
sleeps with the mouth open,
and the pressurized air flows
out through the mouth,
causing a blockage in the
respiratory tract.
Use a chin strap to prevent the
mouth from opening during sleep,
or use a full-face mask. Contact
your physician for details.
The device is too
noisy
The tubing is not connected
properly.
Reconnect the tubing properly.
Air delivered from
the device is
abnormally hot
The air inlet of the device may
be partially blocked, leading to
insufficient airflow into the
device.
Replace the air filter (see 18.7
Replacing the Air Filter / PM2.5
Filter), and clean the air inlet.
Place the device in an area where
air flows freely, and make sure
that the device is at least 20
centimeters away from the wall,
curtain, or other things.
