4.2.2 NIBP Functional Test
This test checks the function of the NIBP measurement. Tools required for this test are: a NIBP
simulator, a T-fitting, an extension tube and an artificial limb.
1. Connect the NIBP simulator to the monitor.
2. Switch on the monitor and the simulator. Perform calibration prior to using the simulator.
3. Set the patient type both on the monitor and in the simulator to adult; respectively set the
systolic pressure and diastolic pressure (mean pressure) to 255/195(215) mmHg (1
mmHg=0.133 kPa). Start a NIBP measurement.
4. Check for the display on the monitor. A difference within the range of ±8 mmHg is
reasonable.
4.2.3 NIBP Leakage Test
This test checks leakage of the airway and the performance of the NIBP system. See Figure 4-1
for details about tools required.
1. Connect the cuff securely with the socket for NIBP air hole.
2. Wrap the cuff around the cylinder with an appropriate size.
3. Make sure the patient type has been set to Adult.
4. Access Menu > User Maintain by inputting the password ABC. Start a leakage test by
selecting NIBP > Leak 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
pressure level again (P2). Safety circuitry on the module only allows the pressure in the
pneumatic system to remain above 10mmHg for 180 seconds. When this safety time limit is
exceeded, the valves will open releasing the pressure. Subtract P2 from P1 and this is the leak
rate per minute.
5. If the alarm information NIBP Leak appears, it indicates that the airway may have air leaks.
