Measurement Alarm message L I Cause and solution
SpO2 Weak Signal L C
SpO2 Weak Pulse L C
SpO2 Low Perf L B
the patient’s condition and change the sensor
application site. If the error persists, replace the
sensor.
SpO2 Interference L C The SpO2 signal has been interfered. Check for
any possible sources of signal noise around the
sensor and check the patient for great motion.
SpO2 Board Fault L C There is a problem with the SpO
2
measurement
board. Do not use the module and contact your
service personnel.
SpO2 Non-Pulsatile L C The pulse signal was so weak that the monitor
cannot perform pulse analysis. Check the patient’s
condition.
NIBP Loose Cuff L C
NIBP Air Leak L C
The NIBP cuff is not properly connected, or there
is a leak in the airway.
NIBP Pneumatic
Leak
L C Check the NIBP cuff and pump for leakages.
NIBP Cuff Type
Wrong
L C The cuff type applied mismatches the patient
category. Verify the patient category and replace
the cuff.
NIBP Air Pressure
Err
L C An error occurred to the air pressure. Verify that
the monitor application site meets the
environmental requirements and check if there is
any source that affects the air pressure.
NIBP Weak Signal L C The patient’s pulse is weak or the cuff is loose.
Check the patient’s condition and change the cuff
application site. If the error persists, replace the
cuff.
NIBP Signal
Saturated
L C The NIBP signal is saturated due to excess motion
or other sources.
NIBP Overrange L C The measured NIBP value is not within the
specified range.
NIBP Excessive
Motion
L C Check the patient’s condition and reduce the
patient motion.
NIBP Cuff
Overpress.
L C The NIBP airway may be occluded. Check the
airway and measure again.
NIBP Equip Err H C
NIBP Timeout L C
NIBP
NIBP Measure
Failed
LC
An error occurred during NIBP measurement and
therefore the monitor cannot perform analysis
correctly. Check the patient’s condition and NIBP
connections, or replace the cuff.
