Functional safety failure
Cause
Sensor or other hardware of
NIBP module is incorrect.
Communication with NIBP
module is failed.
Cuff is no properly wrapped
or no cuff exists.
Cuff, hose or connector is dama-
ged.
Stable pressure value is not avai-
lable. e.g. hoses are
tangled.
Cuff is too loose or patient pulse
is too weak.
specified upper limit.
Affected by arm motion, signal
noise is too large or pulse rate is
not regular.
Pressure has exceeded the
specified upper safety limit.
During pneumatic test, leak
is detected.
Operation of blood pressure
pump system is failed.
Cuff type does not comply
with the patient type.
Measuring time has exceeded
120 seconds (adult) or 90
seconds (neonatal).
Abnormal module reset
Problem happens when
measuring the curve. The system
cannot perform measurement,
analysis or calculation.

Alarm
Remedy
Level
HIGH
Stop using measuring function of NIBP
module, notify biomedical engineer
or Our service staff.
HIGH
If failure persists, stop using measuring
function of NIBP module, notify biome-
dical engineer or Our service staff.
LOW
Properly wrap the cuff
LOW
Check and replace the leaking parts,
if required, notify biomedical engineer
or Our service staff.
LOW
Check if the hoses are tangled, if failure
persists, notify biomedical engineer
or Our service staff.
LOW
Use other method to measure blood
pressure.
HIGH
Reset NIBP module, if failure persists,
stop using measuring function of NIBP
module, notify biomedical engineer
or Our service staff.

Measure again, if failure persists, stop
using measuring function of NIBP
module and notify biomedical engineer
or Our service staff.
LOW
Stop the patient from moving.
LOW
Check and replace the leaking parts,
if required, notify biomedical engineer
or Our service staff.
HIGH
Stop using measuring function of NIBP
module, notify biomedical engineer or
Our service staff.
LOW
Select appropriate cuff type
HIGH
Measure again or use other measuring
method.
HIGH
Reset again
HIGH
Check the cuff. Make sure that the
patient under monitoring is motionless.
Measure again.
