3.2.4.7 Testing the lead fail detection
Reset HR on the simulator to 60.
Reactivate monitoring with the silence audible alarm button (8) , yellow LED goes off.
Select lead V for channel 1.
Detach the electrodes LA, LL, RA and C one after the other but only one. After detaching
each separate electrode the message “Lead Fail” appears and an intermittent alarm
signal can be heard.
3.2.5 NI blood pressure performance check
3.2.5.1 Leakage test
Cuff, pressure manometer, tubing, T-piece and pumpball are to be connected up as
shown in diagrams “Pneumatic Circuit for NBP Performance Check”.
The cuff should be rolled up tightly, preferably around a piece of PVC tubing of external
diameter 12cm.
Press F1 and F5 simultaneously.
Press F3 and F4 simultaneously. Ensure the bulb control is open.
Keep F5 depressed until mano mode is displayed on the screen.
Using the pumpball inflate to 220 mmHg and wait for about 30 s. From now on, the drop
down of pressure must be less than 4 mmHg/min.
3.2.5.2 Testing display errors
Increase pressure and then deflate. Test the tolerance of the displayed values with the
following pressures:
50 mmHg, 100 mmHg, 150 mmHg, 200 mmHg, 250 mmHg
The displayed value for the Eagle 1000 has to be within the tolerance limits of +/- 3 mmHg.
When using a pressure manometer other than the one recommended its error tolerance
limits are to be taken into account.
