4.4 NIBP Error Message and Explanations
4.5 Maintenance and Cleaning
Warning
• Do not squeeze the rubber tube on the cuff.
• Do not allow liquid to enter the connector socket at the front
of the equipment.
• Do not wipe the inner part of the connector socket when cleaning
the equipment.
Reusable Blood Pressure Cuff
The cuff can be sterilized by means of conventional autoclaving, gas,
or radiation sterilization in hot air ovens or disinfected by immersion
in decontamination solutions, but remember to remove the rubber bag
if you use this method. The cuff should not be dry-cleaned.
The cuff can also be machine-washed or hand-washed, the latter method
may prolong the service life of the cuff. Before washing, remove the latex
rubber bag, and for machine-washing, close the Velcro fastening.
Allow the cuff to dry thoroughly after washing, then reinsert the rubber bag.
Explanation
Cause
Self-test failure
A/D sampling error
Loose cuff
Cuff is not connected correctly
Air leakage
Air leakage in the valve or airway
Atmospheric pressure error
Valve cannot be open.
Signal is too weak
Object measuring the pulse is too weak or the cuff
is loose
It is over the range
Object measuring blood pressure is over the
measurement range
Excessive movement
When measuring, signal the presence of excessive
movement or pseudo-differential interference
Overpressure
Cuff pressure is over the scope, ADU 300 mmHg,
Newborn: 150mmHg
Saturated signal
Movement or other factors lead to too big signal
amplitude
Air leakage
There is air leakage in the airway
System failure
There is something wrong with NIBP module, A/D
sampling or soft of system after turning on the device
It spends too much time
Adult: When cuff pressure is 2KPa (15mmHg,)
it may spend 3 minute (180S)
Newborn: When cuff pressure is 0.67KPa (5mmHg,)
it may spend 90S
