LOOSE CUFF 1. Cuff is completely unwrapped.
2. The cuff is not connected.
3. Adult cuff used in neonate mode.
AIR LEAK Air leak in pneumatics, hose, or cuff.
ERROR
Unable to maintain stable cuff pressure,
e.g. kinked hose.
WEAK SIGNAL Very weak patient signal due to a loosely
wrapped cuff. The pulse of patient is too
weak.
RANGE EXCEEDED Measurement range exceeds module
specification.
EXCESSIVE MOTION
1.Too many retries due to interference of
motion artifact.
2.
Signal is too noisy during measurement,
e.g. patient has severe tremor.
3.Irregular pulse rate, e.g. arrhythmia.
OVERPRESSURE
SENSED
Cuff pressure exceeds the specified high
safety limit. Could be due to rapid
squeezing or bumping of cuff.
Medium
SIGNAL SATURATED
Large motion artifact that saturates the
BP amplifier’s amplitude handing
capability.
Low
PNEUMATIC LEAK
Module reports Air Leakage failure while
in the Pneumatic Test mode.
SYSTEM FAILURE Module occurs abnormal processor event.
TIME OUT Measurement took more than 120
