Calibrating Reusable Transducer CPJ840J6
Depending on your monitor’s configuration, you may be able to perform a calibration in monitoring
mode. Perform a mercury calibration when you use a new transducer, and at regular intervals according
to your hospital policy. You require:
• standard sphygmomanometer.
• sterile 10cc syringe with heparinised solution.
• 3-way stopcock.
• approximately 25cm of tubing.
Making the Pressure Calibration
WARNING Never perform the invasive pressure calibration while a patient is being monitored.
1 Zero the transducer.
2 Connect the syringe and manometer.
a. Attach the tubing to the manometer.
b. Connect the 3-way stopcock to the stopcock that is not connected to the patient catheter when
you measure a patient.
c. Attach the syringe to one port and the manometer tubing to the other port.
d. Open the port to the manometer.
3 Move the syringe barrel in and raise the mercury to 200mmHg (30kPa). 200mmHg is the
recommended calibration pressure.
4 In the Setup Pressure menu, select Cal. Press.
