Operating Instructions –
Breathing From the Portable
1. Attach both ends of a dual-lumen cannula to the
connection ports on the H300/H850. Either end
of the cannula may be attached to either connec-
tion port on the portable.
2. Position the nasal cannula properly on your face
so that you will be able to breathe comfortably.
3. Turn the flow control knob until the setting pre-
scribed by your physician is fully visible in the
window on top of the H300/H850.
4. Breathe normally, inhaling through your nose.
Oxygen delivery will not begin until you inhale
through the nasal cannula.
NOTE: If the unit is on a demand (pulse) setting,
you will notice a small pulse at the beginning of
each inhalation. Oxygen is delivered during this
pulse, and continues as long as you inhale. Oxygen
flow stops when you stop inhaling.
NOTE: If the unit is in continuous flow, the H300/
H850 will deliver a steady stream of oxygen. You
must continue to breathe through the nasal cannula
normally to continue receiving continuous flow.
Note: Due to the possibility of excessive moisture/
ice build up it is recommended that the H300/
H850 remain idle for 1 hour after use to decrease
moisture buildup.
5. You should be receiving oxygen flow now.
Verify that you feel oxygen delivery.
6. Use the duration charts available at www.
CAIREmedical.com as a guideline to determine
the length of time the H300/H850 will operate.
7. Under certain conditions (especially continuous
use when the portable is not moved) the H300/
H850 may develop frost on the case. You may
reduce this frost by wiping any accumulated
frost off the case.
8. To stop the flow of oxygen, turn the flow control
knob to the off (0) position.
Caution:
Always turn the flow con-
trol knob off (0) when not in use.
NOTE: Do not open the vent valve
during normal operation.
NOTE: The H300/H850 may be oper-
ated in an upright position, flat on
its back, or any position in between
these two locations.
