NIBP Monitoring
Procedure of the air leakage test:
Connect the cuff securely with the socket for NIBP air hole.
Wrap the cuff around the cylinder of an appropriate size.
Access the NIBP SETUP menu.
Turn the knob to the PNEUMATIC item and press the knob. Then the prompt "Pneum
testing^" will appear on the bottom of the NIBP parameter area indicating that the
system has started performing pneumatic test.
The system will automatically inflate the pneumatic system to about 180mmHg.
After about 20 seconds, the system will automatically open the deflating valve, which
marks the completion of a pneumatic measurement.
If no prompt appears on the bottom of the NIBP parameter area, it indicates that the
airway is in good situation and no air leaks exist. However if the prompt "PNEUMATIC
LEAK" appears in the place, it indicates that the airway may have air leaks. In this case,
you should check for loose connection. After confirming secure connections, you should
re-perform the pneumatic test. If the failure prompt still appears, please contact the
manufacturer for repair.

13.4 NIBP Alarm Message
Among physiological alarms, those belonging to the type that the parameter has exceeded
the limits may activate the recorder to automatically output the parameters and related
measured waveforms when the alarms occur under the condition that the alarm record switch
in the related menu is ON.
Tables below describe the possible physiological alarms, technical alarms and prompt
messages occurring during NIBP measurement.
Physiological alarms:
Message Cause Alarm Level
NS TOO HIGH NIBP SYS measuring value is User-selectable
above upper alarm limit.
NS TOO LOW NIBP SYS measuring value is User-selectable
below lower alarm limit.
ND TOO HIGH NIBP DIA measuring value is User-selectable
above upper alarm limit.
ND TOO LOW NIBP DIA measuring value is User-selectable
below lower alarm limit.
NM TOO HIGN NIBP MAP measuring value is User-selectable
above upper alarm limit.
