Frequently Asked Questions
Question Answer
The pressure tracing
is damped—what
can I do to improve
it? Remember that the tubing fi lled with contrast will always result in a damped
pressure waveform. (You can save contrast by fl ushing forward into a
syringe.) If you need to see a better pressure tracing you will need to fl ush
the tubing with saline. This can be done in several ways.
•
Check that the disposable pressure transducer cartridge is properly
seated in the backplate sensor.
• Check the system for air bubbles.
• Aspirate fl uid from the catheter with a hand syringe attached to the
high-pressure stopcock and hand fl ush the catheter with saline.
• Press the Saline button on the hand controller to fl ush the entire tubing
with saline.
• Press the FLUSH button in the SELECT MODE box of the touchscreen.
The Status window will show the following message: Press and Hold
Flush to
fl ush tubing. While the FLUSH button is held down, the tubing
will be fl ushed with saline for a maximum of 10 seconds. If more fl ush is
desired, press and hold the FLUSH button again.
• Zero the in-line ACIST-supplied pressure transducer to the system.
The hand controller
is not working. What
should I do? Check the following items.
1. Check the hand controller connections on the bottom of the control
panel to be sure they are attached properly. You may need to tighten
them or disconnect them and then connect them again.
2. Check for kinks in the tubing.
3. If the hand controller still will not calibrate, replace it.
Functional Errors
Functional errors occur during a procedure and are displayed in the status window. Sensors within
the system are activated when functional errors occur. An error message will be displayed in the
Status window. Follow the directions given in the window to clear the problem.
Problem Corrective Action
Air column detect
messages are not
displayed when
expected (for example,
when there are air
bubbles present) Wetness on the exterior of the tubing may interfere with the air column
detect sensor’s ability to detect air bubbles. Fluids that are present on the
exterior of the tubing—such as contrast, normal saline, gels or cleaning
solutions—can present a “masking” barrier for the sensor. Be sure to
wipe the sensor and the exterior tubing dry before beginning a case.
Contrast empty
message is given in
error. Make sure the contrast sensor is clipped around the spike tubing and that
the sensor is clean. If contrast build up occurs on the sensor you may get
a false reading.
Contrast is leaking
from syringe or
contrast spike 1. Close the white contrast spike clamp before changing the patient kit.
2. Press the Standby button and check the connection of the contrast
spike.
