Pressure tracing is damped. How can this be improved?
• When the patient tubing and catheter are lled with contrast, the pressure
waveform will always be damped. A saline ush may provide a better
pressure tracing.
• Make sure that the pressure transducer is securely attached to the backplate.
• Check the system for air bubbles.
• Zero the pressure transducer.
Why are air column detect messages not being displayed when
expected?
Wetness (for example, contrast, saline, gels, cleaning solutions) on the exterior
surface of the patient tubing may interfere with the air column detect sensor.
e sensor's eectiveness can also be reduced if it is not cleaned.
Clean the sensor with warm water. Wipe dry both the sensor and the tubing's
exterior surface.
Note
The air column detect sensor is not a substitute for user vigilance.
A contrast empty error is displayed when the contrast container is
not empty. Why?
• Make sure the white slide clamp is open.
• Make sure that the contrast tubing is secured in the contrast sensor.
• Make sure that the contrast sensor is clean.
Contrast is leaking from the syringe or contrast spike. Why?
• Close the white slide clamp before changing a patient kit.
• Press the Standby button and check the connection of the contrast spike.
