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:
standard sphygmomanometer.
sterile 10cc syringe with heparinised solution.
3-way stopcock.
approximately 25 cm of tubing.
NOTE
Only reusable transducers must be calibrated.
Making the Pressure Calibration
WARNING
Never perform the invasive pressure calibration while a patient is being monitored.
1
Zero the transducer.
Connect the syringe and manometer.
2
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.
Corrective Action
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
transducer.
Make sure that the transducer is vented to air, not to the patient, and try
again.
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
Pressure menu, select the pressure's label.
