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.
1Zero the transducer.
2Connect 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.
3Move the syringe barrel in and raise the mercury to 200mmHg (30kPa). 200mmHg is the
recommended calibration pressure.
