13.8 Calibrating NIBP

NIBP is not user-calibrated. Cuff-pressure transducers must be verified and calibrated, if
necessary, at least once every two years by a qualified service professional. See the Service
Manual for details.

13.9 Leakage Test

Leakage test is used to detect the air tightness of the NIBP pump, valve, and trachea. If not, the
system will display NIBP leakage. NIBP leak detection should be performed at least once every
two years or when you think the measurement is inaccurate.
WARNING
This leakage test other than being specified in the ISO 81060-1 standard is to be used by
the user to simply determine whether there are air leaks in the NIBP airway. If at the end
of the test the system gives the prompt that the NIBP airway has air leaks, please contact
the manufacturer for repair.
Procedure of Leakage Test
1. Connect the cuff securely with the socket for NIBP air hole.
2. Wrap the cuff around the cylinder of an appropriate size; don't wrap the cuff around limbs.
3. Make sure the patient type has been set to Adult.
4. Access Menu > User Maintain.
5. Select Leakage Test in NIBP. Then the prompt Leak. Test Running will appear indicating
that the system has started the leakage test.
For EDAN module:
The system will automatically inflate the pneumatic system to about 180 mmHg. After 20
seconds to 40 seconds, if system leakage has detected, the system will automatically open the
deflating valve to stop the leak test and indicates NIBP Leak. If no system leakage is detected
when the pneumatic system is inflated to 180 mmHg, the system will perform a deflation to an
approximate value of 40 mmHg and subsequently perform the second phase leak test. After 20
seconds to 40 seconds, the system will automatically open the deflating valve and provide
corresponding indication based on the test result.
For SunTech module:
NOTE:
When applying high pressures; take special care to increase the pressure at a rate that
will not cause unwanted overpressure errors (300 mmHg).
Manually inflate the pneumatic system to approximately 250 mmHg. Start the timer and wait 60
seconds for the pneumatic system to reach its pressure equilibrium point. After the waiting period,
record the pneumatic pressure level (P1) and wait another 60 seconds and record the pneumatic
