3. Excessive frost and hissing.
•
Some hissing and frosting on the H300-50
Portable is normal. If, however, the hissing
sound from the H300-50 Portable continues
after a fill or anytime during usage, combined
with excessive frosting on the H300-50
Portable, stop using the H300-50 Portable
and contact your Homecare Provider.
•
Excessive frost formation on the H300-50
Portable 30 minutes after a fill while the Flow
Control knob is in the OFF position may be a
result of possible system malfunction. Stop
using the H300-50 Portable and contact your
Homecare Provider for service.
4. The H300-50 Portable stops pulsing during
use.
•
Ensure that both connections of the dual-
lumen cannula are firmly attached to the
Oxygen Outlet and Sense connectors.
•
Change the cannula if water droplets are
present from humidified exhaled gas.
Replacing the cannula with a dry one
enhances the ability of the H300-50 Portable
to pulse.
•
Ensure that the cannula is not kinked or
pinched.
•
Ensure that the cannula tips remain in your
nostrils and do not slide to one side.
•
Ensure that there is oxygen in the H300-50
Portable.
