to the oxygen outlet,
open and close the
cannula port repeatedly
to discharge the water
droplets).
1) There is no safe ventilation
around the device, resulting in
working temperature too high.
1) Make sure that the device is at
least 20cm away from the wall or other
blockages and heaters.

water vapor.
5) The nasal oxygen cannula is
collapsed.
5) Straighten out the nasal oxygen
cannula.
6) The internal fan is not working
properly., resulting in high working
