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 AirSep’s
NewLife Intensity or NewLife Intensity 10, 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.
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.
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.
