7. Set the desired flow on each flowmeter used
at the flow stations. The maximum flow will
be dependant on the capacity of the oxygen
concentrator used. The sum of the flow settings on
the flow station's flowmeters must not exceed the
total capacity of the oxygen concentrator.
WARNING: IT IS VERY IMPORTANT TO RE-ADJUST
THE FLOWS AS NECESSARY ON ALL
FLOWMETERS BEING USED ON THE FLOW
STATIONS EACH TIME ADJUSTMENT OR
DISCONTINUED USE TO ONE OR MORE OF THE
FLOWMETERS IS MADE TO ENSURE ACCURATE PRESCRIPTIONS
ARE ADMINISTERED THROUGH ALL OXYGEN OUTLETS ON THE
UNIT. IT MAY TAKE SEVERAL ADJUSTMENTS TO STABILIZE THE
FLOW ON THE SUREFLOW FLOWMETERS.
8. Observe that the flowmeter on the oxygen concentrator
now indicates the total combined amount of flow in use at
the flow stations, which are connected.
CAUTION: It is desirable to establish a
protocol to monitor and verify flows at all
SureFlow outlets as well as from the oxygen
concentrator on a periodic basis.
Units Equipped with Barb Fitting Oxygen
Outlets
When connecting oxygen concentrators with a barb
fitting as the oxygen outlet the oxygen hosing will not be
needed.
Instead, securely connect standard oxygen tubing to the
barb fitting on the oxygen concentrator and then using
an oxygen adapter (part number F0025-1) on the inlet of
the SureFlow flow station, connect the other end of the
tubing. (See Figure 5.)

Cleaning
Do not use abrasive powders or chemicals. Clean only the
exterior of the SureFlow unit, which can be disinfected
with either a common chemical disinfectant or a diluted
solution* of household bleach (sodium hypochlorite
5.25%). To use effectively, mix a solution of 1:100
parts of bleach to water. Wear eye and skin protection
and allow the solution to remain on the surface for 10
minutes. After using the disinfecting solution, rinse with
water and wipe dry. Make sure unit is completely dry and
then retest it before you return it to inventory.
* The manufacturers of sodium hypochlorite products recommend
various strengths of a bleach solution for killing bacteria, etc.,
based on the type of germ to disinfect; however, a generally
recommended solution is ¾ cups (237 ml) of household bleach per
gallon (3.79 L) of water.
