Note: Before setting flowmeters, ensure that the SureFlow station
is level, and that you are at the correct viewing angle to properly
read and adjust the settings. (See Figure 3.) Whether the flow
stations are mounted on a wall or located on a desk or table-top,
make sure that you are positioned in front of the flowmeters to
be adjusted (bending down to eye level as necessary), so that
when looking at the flowmeter, each of its back and front black,
horizontal line markings are in exact alignment (appear as just
one horizontal line per increment). Proper adjustment will appear
to split the flowmeter ball horizontally across the center of the
ball as just one line.
7. Set the desired flow on each flowmeter used at the
flow station. 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 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
STATION 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 SureFlow flow
station.
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.
WARNING: AIRSEP NEWLIFE INTENSITY
OXYGEN CONCENTRATOR MODELS REQUIRE A
MINIMUM FLOWRATE OF 2 LPM TO ACHIEVE
HIGH CONCENTRATION OXYGEN. WHEN
SUREFLOW IS USED WITH THE INTENSITY,
ENSURE THE COMBINED FLOWRATE IS AT LEAST 2 LPM. IF
COMBINED PATIENT USE IS BELOW 2 LPM, IT WILL BE
NECESSARY TO VENT SOME OF THE OXYGEN TO
ATMOSPHERE THROUGH AN UNUSED OXYGEN OUTLET ON
THE SUREFLOW IN ORDER TO ACHIEVE A TOTAL FLOWRATE
OF AT LEAST 2 LPM.
Oxygen from Dual Flow Concentrators
If the oxygen source for the SureFlow station(s) is
made available from an oxygen concentrator with two
flowmeters and two outlets, such as from the NewLife
Intensity, it is possible to use one of the flowmeters on
the concentrator for SureFlow and to use the second
flowmeter for another application.
For example, if the SureFlow is using a total combined
flow of 4 LPM from a NewLife Intensity 10 (which
has been set for its maximum capacity of 10 LPM),
the flowmeter corresponding to the outlet connected to
SureFlow reflects the 4 LPM flow in use. This allows
a maximum of 6 LPM to be set on the secondary
flowmeter for another oxygen application.
