2. The H300-50 Portable has two delivery modes:
continuous and demand. Turn the flow control
knob on the top of the H300-50 Portable
clockwise from 0 to .75 for continuous flow and,
continuing clockwise, from 1-4 for demand flow.
(Figure 9).
Figure 9: Setting the flow rate
Set your rate to the setting prescribed by your
physician. The flow setting value should be
clearly 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 set-
tings.
When a demand mode setting is selected, oxygen
will be delivered only while you inhale. You
should notice a small pulse at the beginning of
each breath. Oxygen is delivered during this
pulse, and continues as long as you inhale.
