Chapter 12: IBP Monitoring
■
Mercury calibration should be performed by the biomedical engineering department either
whenever a new transducer is used, or when system accuracy is in doubt.
■
The purpose of the calibration is to ensure that the system gives you accurate measurements.
■
Before starting a mercury calibration, a zero procedure must be performed.
Warning
You must never perform this procedure while patient is being monitored.
Transducer calibration:
1. Attach the tubing to the sphygmomanometer.
2. Ensure that connection that would lead to patient is off.
3. Connect the 3-way connector to the 3-way stopcock that is not connected to the patient
catheter.
4.Open the port of the 3-way stopcock to the sphygmomanometer.
5. Raise the sphygmomanometer to set value that you adjusted in CALIB WINDOW menu.
6. Choose a CAL-> in the CALIB WINDOW menu.
7. Press the rotary knob to start the calibration.
The message "PLEASE WAIT" will be displayed during the procedure. "IBP1/IBP2
CALIBRATION OK" indicates that the calibration procedure is completed successfully.The last
calibration time will be saved and displayed in its corresponding place.
The following messages may prompt up in CALIB WINDOW:
■
"IBP1/IBP2 NO SENSOR, UNABLE TO CALIBRATE"
Make sure that the transducer is connected or not, then start calibration procedure.
■
"IBP1/IBP2 OVERANGE, UNABLE TO CALIBRATE"
Verify that adjusted pressure in the menu and sphygmomanometer pressure are equal.If the
problem still exists, contact after sale service.
■
"IBP1/IBP2 UNSTABLE PRESSURE, UNABLE TO CALIBRATE"
Make sure that the transducer is not attached to the patient or perhaps the tubing system is
hit accidentally .If the problem persists, contact after sales service.
8. Remove the sphygmomanometer tubing and extra connector.
