2. Vent the transducer to atmospheric pressure by turning on the stopcock to the air.
3. Press the
hardkey on the module, or, in the setup menu for the pressure (e.g. Art),
select [Art Zero >>]→[Zero]. During zero calibration, the [Zero] button appears
dimmed. It recovers after the zero calibration is completed.
4. After the zero calibration is completed, close the stopcock to the air and open the
stopcock to the patient.
NOTE
z Your hospital policy may recommend that the ICP transducer is zeroed less
frequently than other transducers.
11.7 Making the Pressure Calibration
A calibration ensures accurate pressure readings. Perform a calibration when you use a new
transducer, and at regular intervals according to your hospital policy. You require:
Standard sphygmomanometer
Balloon pump
Tubing
T-shape connector
WARNING
z Never perform the invasive pressure calibration while a patient is being monitored.
