6. While visualizing under fluoroscopy, gently and slowly withdraw the
Torque Catheter past the Cordella Sensor, making sure not to disturb
the Cordella Sensor location. Leave the Stability Sheath in place near
the newly deployed Cordella Sensor. Once the Torque Catheter is fully
removed, separate the guidewire and discard the Torque Catheter.
WARNING: If the Torque Catheter engages the
Cordella Sensor, stop withdrawing the Torque
Catheter, rotate approximately 90 degrees and
resume slow, gentle retraction until clear of the
Cordella Sensor.
7. Use the Stability Sheath as a fluid-filled column to obtain a reference
pressure by attaching the side port to the pressure transducer, making
sure to:
Adjust the pressure transducer height to half of patient’s chest
height
Flush the catheter and fluid line to ensure there are no air bubbles
Zero the measurement
Check that the catheter tip is positioned within the PA and that
the catheter does not cross the Sensor.
8. Screw the tethered blue luer cap onto the Stability Sheath hub to
prevent back-bleeding through the hemostasis valve.
WARNING: Avoid torquing the Stability Sheath when
used as a fluid-filled column. Torquing can result
in kinks which inhibit accurate reference pressure
measurements for Sensor calibration.
4.7 Calibrating the Sensor
NOTE: During Reader operation, electromagnetic interference (EMI)
generating equipment may need to be temporarily moved away from the
Reader’s zone of operation. This may include temporarily repositioning
any ECG leads, pagers, or patient monitoring systems away from the
Reader.
WARNING: DO NOT USE 450MHz devices, such as
Walkie Talkies or intercom systems, near the Reader.
1. The CalEQ system will prompt
the user to zero the reference
pressure.
2. Enter the systolic and diastolic
values from the fluid-filled pressure
measurements on the patient
monitor. Press the “Next” button.
3. Undock the Reader when
prompted. CalEQ will proceed to
the Calibrate Sensor screen, where
it will show a live, uncalibrated
waveform. Adjust the position of
the Reader over the patient’s chest
until the signal percentage is as
high as possible (>75%). Once signal
percentage above 75% is achieved,
hold the Reader still for 20 seconds
and monitor the waveform in
preparation for calibration.
