Condition
NIBP
The non-invasive blood pressure
mean measurement has violated an
alarm limit setting.
NIBP
The non-invasive blood pressure
diastolic measurement has violated
an alarm limit setting.
NIBP
The non-invasive blood pressure
data, once present, can no longer
be produced.
What to Do
An ECG lead (or electrode) required to measure the lead view is faulty or disconnected:
• Ensure that the ECG lead cable is connected to the wECG module, and that the wECG module
has sufficient battery power.
• Ensure that each ECG lead cable clip is connected to the Quadtrode electrode contact.
(Examine the ECG VS box for indications of a contact problem, where LL = left leg, LA = left
arm, and RA = right arm, and LL, LA, RA, = RL [right leg] or all leads.)
• Replace the ECG lead cable.
• Replace the Quadtrode electrode.
Notes
The error message can be displayed for trace A and/or for trace B.
May also be displayed when high DC offsets are present on an input lead.
Indication
Flashing yellow mean numeric in the NIBP VS
box, yellow alarm light, medium priority alarm
tone, where OVR displayed if the value is
greater than the highest specified or UND if
the value is less than the lowest specified
Flashing yellow diastolic numeric in the NIBP
VS box, yellow alarm light, medium priority
