Introduction to the SureFlow Oxygen Flow Station
SureFlow™ is a uniquely engineered flow station developed by AirSep®
Corporation for economically administering medical-grade oxygen to
multiple patients from an oxygen concentrator or other oxygen source(gas or liquid).
This product enables clinicians and medics around the world tomanage and redirect the flow from a single oxygen source to a simple
flow station to serve up to five individuals per SureFlow unit.
Two or more SureFlow units can be connected together to serve evenmore individuals simultaneously. Each flowmeter is adjusted separately
to ensure precise control with a visual indication of flow for safety andcomfort.
Dual flow models of NewLife® Intensity 8 and 10 LPM concentrators
provide greater flexibility in delivering oxygen by allowing SureFlow tooperate connected to one of the concentrator’s flowmeters while thesecondary flowmeter can supply oxygen for a nebulizer treatment or ahigher flow patient.
SureFlow units also meet the low flow oxygen needs of pediatricpatients in a critical care nursery in developing countries around theglobe. The standard SureFlow is configured with 5 low flow flowmeters,
which display in 0.10 increments, and can be used in a wide range ofsettings from 0.10 to 1.0 LPM. SureFlow can also be specially orderedwith a combination of 1 LPM and 5 LPM flowmeters, or with five 2 LPM
flowmeters which display in 1/8 LPM increments.
The SureFlow is a simple device that will not require a regular service
schedule.
Two procedures, one for flowmeter replacement and one for inlet
valve replacement, are included in the unlikely event that a repair isneeded. The flowmeter or inlet/outlet valve may need replacement if it
becomes damaged, or begins to leak.

9. Leak Testing
After any servicing is complete, the SureFlow should be checked
for leaks, Attach to oxygen source and using soapy water or aleak test solution, check all tubing connections before closing.
Another aid in determining the source of a leak(s) is to put yourthumb over each outlet at the SureFlow station, on at a time. Theflowmeter ball must drop to zero on each test, indicating no leakwithin the SureFlow.
10. Replace the back cover after leak testing, and use three screws
to complete the flowmeter replacement.

Oxygen Flow Station Provider Technical ManualCleaning
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 thedisinfecting solution, rinse with water and wipe dry. Make sure unit iscompletely 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.
