Calibrating Reusable Transducers
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:
sterile 10cc syringe with heparinised solution.
approximately 25 cm of tubing.
Only reusable transducers must be calibrated.
Making the Pressure Calibration
Never perform the invasive pressure calibration while a patient is being monitored.
Zero the transducer.
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.
Make sure that the transducer is connected and try again. If this fails,
exchange the adapter cable and try again. If this fails, exchange the
Make sure that the transducer is vented to air, not to the patient, and try
Try pressing the Zero key again. If this fails, replace the transducer and
adapter cable and contact your service personnel.
Pressure measurement is switched off. To switch it on, in the Setup
