Set your rate to the setting prescribed by yourphysician. The flow setting value should beclearly readable in the center of the window. The
H300-50 Portable will not deliver oxygen to you
if the flow control knob is set between flow settings.
When a demand mode setting is selected, oxygen
will be delivered only while you inhale. You
should notice a small pulse at the beginning ofeach breath. Oxygen is delivered during thispulse, and continues as long as you inhale.

25

How To Use Your H300-50 Personal Oxygen System

Oxygen flow stops when you stop inhaling. It is
normal for the device to occasionally skip abreath or to pulse twice in one breath.
When continuous mode is selected, oxygen isdelivered continuously at the rate displayed on
the flow control knob. For example, the .75 setting delivers continuous flow oxygen at .75 L/
min.

Notes:• Make sure that the tips remain in your nostrils
and do not slide to one side.
• Occasionally water droplets caused by exhaledhumidity may accumulate in the cannula. This
may disrupt the operation of the oxygenconserving device. If this happens, replace themoist cannula with a dry one. Allow the moist
cannula to dry before using it again.
• Currently, there are two dual-lumen cannuladesigns available for use with the H300-50.
One cannula provides sensing and delivery ofoxygen in each nostril. This is the best one touse when experiencing a blocked nasal
passage. The second provides oxygen only to
one side of the nose and senses when to provide
oxygen on the other. Also, the tips of thissecond type are slightly smaller and softer.

29

How To Use Your H300-50 Personal Oxygen System

The following information is intended to help you
troubleshoot and solve simple operational problems
that you may experience when using your H300-50
Portable.
1. The H300-50 Portable does not pulse after
filling.
If during the filling process, the H300-50 Portable is disengaged with the vent valve lever down,pressure may be reduced within the H300-50 Portable causing a delay in the conserving device
function. It may require as much as 60 minutes torestore adequate pressure for proper oxygen flow.
Additionally, improper filling or lower than normal operating pressure in the Reservoir will contribute to the H300-50 Portable not pulsing.
2. The H300-50 Portable makes a hissing sound.
Hissing can occur to maintain the correct operating pressure within the H300-50 Portable. It is
most likely to hiss after filling or when the position of the H300-50 Portable is changed. Hissing
can last for approximately 10 minutes after filling. Additionally, it can occur when the flow control valve is at a low setting.

35

Troubleshooting

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, combinedwith 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 yourHomecare Provider for service.

4. The H300-50 Portable stops pulsing during
use.

36

•

Ensure that both connections of the duallumen cannula are firmly attached to the
Oxygen Outlet and Sense connectors.

•

Change the cannula if water droplets arepresent from humidified exhaled gas.
Replacing the cannula with a dry one
enhances the ability of the H300-50 Portableto pulse.

•

Ensure that the cannula is not kinked or
pinched.

•Ensure that the cannula tips remain in yournostrils and do not slide to one side.

•

Ensure that there is oxygen in the H300-50
Portable.

H300-50 Home Use Guide

Troubleshooting•

With the cannula on, close your mouth andbreathe only through your nose to verify thatthe H300-50 Portable has stopped pulsing.

5. The H300-50 Portable does not fill.
•

Verify that there is oxygen in the Reservoir.
If the Reservoir has a pressure gauge, makesure it reads between 47-psi and 58-psi.

•

Ensure that the H300-50 Portable andReservoir fill connectors are fully engaged
throughout the filling process.

6. The H300-50 Portable vent valve does not
close properly at the end of the filling process.
If the vent valve fails to close and the hissing
sound and oxygen vapor cloud continue, carefully remove the H300-50 Portable by gently
rotating the Portable counter-clockwise and lifting from the Reservoir. Venting from the bottomof the H300-50 Portable will stop in a few minutes. Keeping the H300-50 Portable upright,
allow it to warm until you can close the ventvalve. The H300-50 Portable may require as
much as 60 minutes to restore adequate pressure
for proper oxygen flow.

37Troubleshooting

7. The H300-50 Portable does not disengage
easily from the Reservoir after filling.
WARNING: Do not bend over the Reservoir fillconnector when disengaging the Portable. Contact
with liquid oxygen can cause personal injury.

The H300-50 Portable and Reservoir fill connectors may have become frozen. Do not use force.
Allow a few minutes for the frozen parts towarm, then disengage the H300-50 Portable
when the ice has melted. To prevent the Reservoir and H300-50 Portable from freezing
together, always wipe the female fill connector
on the Reservoir and the male fill connector on
the H300-50 Portable with a clean, dry, oil-free
cloth before filling.
