4. When you see the message Zero Ok, please close the stopcock to atmospheric pressure, and
open the stopcock to the patient.
15.7 Troubleshooting the Pressure Zeroing (Taking Art for
Example)
The status message lists the probable cause of an unsuccessful calibration.
Message
Corrective Action
Art ZERO FAIL
Make sure that the transducer is not attached to the patient
Art SENSOR OFF, FAIL
Make sure that transducer is not off, and then proceed
zeroing
IN DEMO, FAIL
Make sure that the monitor is not in DEMO mode. Contact
service technician if necessary
PRESSURE OVER RANGE,
FAIL
Make sure that the stopcock is vented to atmosphere. If the
problem persists, please contact service technician
PULSATILE PRESSURE
ZERO FAIL
Make sure that the transducer is vented to air, not connected
to a patient, and try again.
15.8 IBP Pressure Calibration
1. Mercury calibration should be performed by the biomedical engineering department either
whenever a new transducer is used, or as frequently as dictated by your Hospital Procedures
Policy.
2. The purpose of the calibration is to ensure that the system gives you accurate measurements.
3. Before starting a mercury calibration, a zero procedure must be performed.
If you need to perform this procedure yourself, you will need the following equipment: Standard
sphygmomanometer, 3-way stopcock and Tubing (approximately 25 cm long).
The calibration procedure is listed below:
1. Close the stopcock that was open to atmospheric pressure for the zero calibration.
2. Attach the tubing to the sphygmomanometer.
3. Ensure that connection to patient is off.
4. Connect the 3-way connector to the 3-way stopcock that is not connected to the patient
catheter.
5. Open the port of the 3-way stopcock to the sphygmomanometer.
6. Select the channel to be calibrated in the menu and select the pressure value to which the IBP
is to be adjusted.
7. Inflate to make the mercury bar rise to the setup pressure value.
8. Adjust repeatedly until the value in the menu is equal to the pressure value shown by the
mercury calibration.
