How To Use Your H850 Personal Oxygen System
30
The H850 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 of each breath. Oxygen
is delivered during this pulse, and continues as long as
you inhale. Oxygen flow stops when you stop inhal-
ing. It is normal for the device to occasionally skip a
breath or to pulse twice in one breath.
When continuous mode is selected, oxygen is deliv-
ered continuously at the rate displayed on the flow
control knob. For example, the 1 setting delivers con-
tinuous flow oxygen at 1 L/min.
