How To Use Your H850 Personal Oxygen System
Notes:
• Make sure that the tips remain in your nostrils
and do not slide to one side.
• Occasionally water droplets caused by exhaled
humidity 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.
• Currently, there are two dual-lumen cannula
designs available for use with the H850. One
cannula provides sensing and delivery of
oxygen in each nostril. This is the best one to
use when experiencing a blocked nasal
passage. The other provides oxygen only to one
side of the nose and senses when to provide
oxygen on the other. Also, the tips are slightly
smaller and softer.
4. The contents indicator will show approximately how
much liquid oxygen remains in the H850 Portable.
To ensure you have enough oxygen to meet your
needs, check the indicator periodically. When
checking the contents, remove any carry accessories
and make sure your nasal cannula is not pulling on the
H850 Portable.
