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:

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 (AirSep Part No. TU056-074), 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).
