However, there are some troubleshooting steps that
you can take if you experience problems with your
CAIRE Companion 5. They are outlined in the
following table. You can use this chart by following
the checks for your problem in numerical order.
Your Action
1. Plug in the electrical cord.
2. Check your household fuse and circuit. Try a
different outlet.
3. Connect to a back-up oxygen supply. Contact your
healthcare provider immediately.
1. Verify that the flow control knob is set on your
appropriate Liter Per Minute (LPM) setting prescribed
by your doctor.
2. Verify that the tubing is tight at all connections
(outlet barb, humidifier bottle, water trap, etc). Re-
secure any connections if necessary.
3. Check for kinks or blockages in your tubing. Repair
if needed.
4. Inspect all tubing and the cannula for leaks. You
can do this by either listening or feeling for escaping
air. Replace leaky tubing or cannula.
5. Verify that nothing is blocking the inlets of the
concentrator. Be sure it is at least 12 inches (30 cm)
away from furniture, walls, or other obstructions.
6. Connect to a back-up oxygen supply. Contact your
healthcare provider immediately.
