Note: The combined flows from the SureFlow flow station and
the secondary flowmeter cannot exceed the total capacity of
the oxygen concentrator. If adjustments to any of the SureFlow
flowmeters is made to increase or decrease the amount of flow,
the result will be that more or less flow will be available for the
secondary flowmeter application.
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.
Using Multiple SureFlow Oxygen Flow
Stations
Two or more SureFlow flow stations can be connected
together to divert the flow from a single oxygen
concentrator or other oxygen source to even more oxygen
outlets to serve additional patients. The maximum
capacity of flow that can be set from all flowmeters
combined from the flow stations must not exceed the
capacity of the oxygen source used.
To supply oxygen to the SureFlow units:
Note: During set-up, nothing is initially connected to the
oxygen concentrator at this time. This is important to prevent
the concentrator from being overdrawn when using with the
SureFlow units.
1. Supply power to the oxygen concentrator, and set
the I/O switch to the I position to turn it on.
2. Set the flowmeter on the oxygen concentrator to
the maximum capacity of the unit (for example
5 LPM, 8 LPM, or 10 LPM, depending on
concentrator model).
3. Use a second 7 ft (2.1 m) oxygen hose (Part No.
CU004-2), to connect the available end of the first
flow station to an inlet fitting on the second flow
station. (See Figure 4.)

4. If more than two flow stations are to be used,
repeat step 3 with additional oxygen hosing and
flow stations.
5. As necessary, test for leaks at all ends of the hose
by applying soapy water to each of the connection
points. If bubbling occurs, then leaks are present,
and the connection must be tightened properly
until leaks are eliminated.
It may be more apparent if there is a leak(s)
by allowing the concentrator to run with all
flowmeters turned off at the flow station. If no
leak is present, the flowmeter on the concentrator
should read zero.
Another aid in determining the source of a leak(s)
is to put your thumb over each outlet at the
SureFlow station, one at a time. The flowmeter
ball must drop to zero on each test, indicating no
leak within the SureFlow station.
6. Attach up to five (5) cannulas per flow station,
depending on how many patients will be receiving
oxygen therapy. Cannula length for each outlet can
be a maximum of 50 feet (15 meters).
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 perfect 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.
