Inaccurate C.O value
Some advices to reduce measurement errors:
● NIBP
When NIBP measurement is taken, it is an important factor to set the measurement unit on
mmHg and connect the pressure cuff to the patient properly and according to instructions of
this manual. The most likely reason that the system doesn't display NIBP value is cuff failure
or leakage, therefore when dealing with this problem, use an intact cuff to test the system and
check air hose connection and other connections. If the problem is not removed, contact the
manufacturer's after sale service.
