Patient Monitor User Manual Monitoring IBP

NOTE:
The pressure option is only valid when the label is P1/P2 and does not take effect under
other labels.
16.3.2 Zeroing the Pressure Transducer
To avoid inaccurate pressure readings, the monitor requires a valid zero. Zero the transducer in
accordance with your hospital policy (at least once per day). You must perform a zero:
When you use a new transducer or tubing;
Every time you reconnect the transducer cable to the monitor;
If you think the monitor’s pressure readings are not correct.
When using a pressure module, the zero information is stored in the module.
The zeroing procedure is listed as below:
1. Turn off the stopcock to the patient.
2. Vent the transducer to atmospheric pressure, to compensate for the static and atmospheric
pressure exerted on the transducer.
3. In the setup menu for the pressure, select Zero Channel: XX or Zero All . ( XX stands for the
IBP label name). After confirmation, the user can zero the pressure of certain channel or
pressure of all channels. After zeroing, the interface displays the result and last calibration
time.
4. When you see the message Zero Ok , please close the stopcock to atmospheric pressure, and
open the stopcock to the patient.
16.3.3 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.
16.3.4 IBP Calibration
IBP is not user-calibrated. Calibration should be performed by a qualified service professional as
