NIBP SELF TEST
ERROR
Transducer or other
hardware of NIBP module is
incorrect.
HIGH
Stop using measuring function of NIBP
module, notify biomedical engineer or Our
service staff.
NIBP COMM ERR
Communication with NIBP
module is failed.
HIGH
If failure persists, stop using measuring
function of NIBP module, notify
biomedical engineer or Our service staff.
NIBP LOOSE CUFF
Cuff is no properly wrapped
or no cuff exists.
LOW
Properly wrap the cuff.
NIBP AIR LEAK
Cuff, hose or connector is
damaged.
LOW
Check and replace the leaking parts, if
required, notify biomedical engineer or Our
service staff.
NIBP AIR PRESSURE
ERROR
Stable pressure value is not
available. e.g. hoses are
tangled.
LOW
Check if the hoses are tangled, if failure
persists, notify biomedical engineer or Our
service staff.
NIBP WEAK SIGNAL
Cuff is too loose or patient
pulse is too weak.
LOW
Use other methods to measure blood
pressure.
NIBP RANGE
EXCEEDED
Measurement range exceeds
the specified upper limit.
HIGH
Reset NIBP module, if failure persists, stop
using measuring function of NIBP module,
notify biomedical engineer or Our service
staff.
NIBP EXCESSIVE
MOTION
Affected by arm motion,
signal noise is too large or
pulse rate is not regular.
LOW
Make sure that the patient under monitoring
is motionless.
NIBP OVER
Pressure has exceeded the
HIGH
Measure again, if failure persists, stop using
