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 25 cm 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.
