Respiration
“0” is displayed for respiration rate.
Cause : The respiration waveform amplitude is below the automatic detection level (0.2 Ω ).
Solution : Change the electrode site where large ECG amplitude can be acquired.
As the respiration detection by impedance method shares the same ECG electrodes,
RR value will not be properly displayed when in “lead off” condition or when
electrode condition is unstable.
NIBP
The cuff is not inflated although the pump is operating.
Cause 1 : The air hose is not firmly connected, and the air is leaking.
Solution : Check if the air hose is properly connected.
Cause 2 : The cuff size is not corresponded to the selected patient type.
Solution : Check if the cuff size is corresponded to the selected patient type.
Cause 3 : The air hose or cuff may be damaged causing air leakage.
Solution : Check that there is no damage (fracture, etc.) on the air hose and cuff.
Cause 4 : Malfunction of the pump, quick exhaust valve, or constant exhaust valve can be
considered.
Solution : Perform NIBP function test, and check that NIBP unit properly operates.
Reference For details of the NIBP function test, refer to “5. Function Test”.
“ERROR” message is displayed and the measurement is ceased.
Cause 1 : The measurement accuracy is not reliable due to body motion artifact.
Solution : Have the patient stay still as much as possible during the measurement.
Cause 2 : The pulse is too small to acquire reliable measurement accuracy.
Solution : Check if the cuff application is proper, and if the cuff size is corresponded to the
selected patient type.
Cause 3 : The applied pressure to the cuff has exceeded the maximum limit.
Solution : Check if the cuff application is proper, if the cuff size is corresponded to the selected
patient type, or if the air hose is not bent. After checking the above, perform the
measurement again.
If the “ERROR” message is displayed again, a failure of the equipment can be
considered. Cease the measurement, and perform NIBP function test on the test
menu.
Reference For details of the NIBP function test, refer to “5. Function Test”.
Solution : Check if the cuff application is proper, or if the cuff size is corresponded to the
selected patient type. Also, a body motion may extend the measurement duration.
Perform the measurement again.
If the “ERROR” message is displayed again, a failure of the equipment can be
considered. Cease the measurement, and perform NIBP function test on the test
menu.
