Using Your HELiOS Marathon H850 Portable Oxygen Unit
Note:
Make sure that the tips remain in your nostrils and do
not slide to one side.
Note:
Occasionally water droplets from condensed
exhalations may accumulate in the cannula. This may
disrupt the operation of the oxygen conserving device.
If this happens, replace the moist cannula with a dry
one. Allow the moist cannula to dry before using it
again.
