Directions for use
IBP zero set
•
Zero Set must be carried out before every application.
•
To prevent incorrect measurement readings due to the sensor's physical null drift,
calibrate the sensor every 24 hours.
Note
1.
Move to the desired IBP measurement field (P1, P2) using the trim knob.
2. Press the trim knob to display the IBP menu.
3. Select Zero Set with the trim knob and press to carry out the zeroing.
4. A straight line is displayed in the IPB waveform.
IBP alarms and messages
Message
IBP needs service
IBP needs calibration Zero-point sensor too high/low
IBP artifact
Incorrect IBP value
displayed
IBPs < [lower limit]
IBPs > [upper limit]
IBPm < [lower limit]
IBPm > [upper limit]
IBPd < [lower limit]
IBPd > [upper limit]
Ensure the sensor is kept still during zero set. If the pressure sensor's position is
moved during zero set, this can lead to incorrect values.
Possible cause
No IBP module detected
by more than ± 30 mmHg or
unsteady pressure
Loose sensor contact
A manipulation at the sensor,
such as rinsing, has caused
variation peaks of ± 150 mmHg
Constant pressure (± 30 mmHg)
during the calibration in the
system
Systolic pressure too low
Systolic pressure too high
Mean pressure too low
Mean pressure too high
Diastolic pressure too low
Diastolic pressure too high
Monitoring and Measurements
Suggested action
Switch off/on.
Replace monitor.
Check tube system, sensor and valves.
Re-calibrate the sensor.
Inspect the sensor and cable connection.
After rinsing, calibrate the sensor.
Check tube system, sensor and valves. Set
three-way valve to ambient pressure.
Re-calibrate the sensor.
