b)
If FlowTrax is mounted to an IV pole, turn it 90 degrees or remove from pole clamp and lay it on its back on
flat/level surface.
c)
Run the pump being tested using its maximum rate it can be programmed for while observing the glass tubes.
Make sure that there are no tiny bubbles in the front glass tube that are not travelling at the same speed as the
primary tracking bubble. These tiny bubbles can interfere with the FlowTrax measurements, and it may be
necessary to momentarily tilt the FlowTrax in order to cause the tiny bubble to attach to the primary /
tracking bubble before starting a low rate test.
d)
Verify FlowTrax does NOT display a “TILT” message before starting a test.
e)
FlowTrax should be used in an upright (vertical) position rates above 20ml/hr and for priming.
7)
Trending:
NOTE: The Trend screen can be used to determine Pass or Fail data from the last test performed. This is
particularly helpful for unattended tests where the user was not able to see the final results before, for example,
KVO started.
•
Press the FUNCTION button, then TREND button.
•
The FlowTrax captures and displays accumulated Volume and average Flow Rates at one minute
intervals for up to 14 minutes.
•
Pressing RESET FLOW button will clear all trend data from previous test.
8)
Occlusion Testing:
NOTE: It is not normally necessary to ZERO pressure repeatedly throughout the day with FlowTrax. In fact, if
an IV Set is attached and the output hose is above FlowTrax at the time zero is pressed, an error may be
introduced to the zero offset and subsequent occlusion measurement. Performing a pressure ZERO is
recommended at the beginning of each day unless a) there is a substantial shift in barometric pressure or b)
FlowTrax is being moved from one location to another where there is a substantial change in altitude.
a)
If pressure ZERO is needed, remove input line from FlowTrax input fitting, press FUNCTION, then CLEAN
GLASS. Press ZERO button on FlowTrax. It may take a few seconds for pressure to zero. Reinstall Input
line, FLUSH and PRIME to start fluid measurements / occlusion tests.
b)
Connect (if not already) IV set to FlowTrax input (left side) fitting.
c)
Select desired units of measure by pressing UNITS button on FlowTrax.
d)
Press RESET FLOW to zero the MAX pressure value.
e)
Program infusion device for desired rate and start infusion device.
f)
Slowly turn occlusion knob on front of FlowTrax clockwise until the infusion device alarms or the occlusion
knob is flush with front of FlowTrax (do not over tighten).
UNITS WITH ELECTRONIC OCCLUSION (E-OCCLUDE) FEATURE:
i)
Press FUNCTION key
ii)
Press 40PSI Occlude soft key at bottom of screen.
iii)
Program infusion device for desired rate and start infusion device.
iv)
Electronic Occlusion Screen will display the maximum pressure at the top of the screen and graph
the results as the pressure in the IV pump rises, until the unit under test reaches the occlusion alarm
threshold, as shown in the figure below. MAX AT equals the total elapsed time to achieve
Occlusion. The pressure value below MAX AT is the real time pressure.
g)
Document “MAX” pressure indicated on FlowTrax.
h)
The last “MAX” pressure will remain on the display for 2 hours, or until “RESET FLOW” is pressed.
