BIS Window 19 Monitoring BIS

♦select Stop Cyclic Check in the BIS Impedance Check Window.

If you stop a Cyclic Impedance Check before the ground electrode has passed, a ground electrode impedance check will be started automatically. This cannot be switched off.

BIS Window

♦To open the BIS window, in the Setup BIS menu, select Show Sensor.

The window may look slightly different on your monitor. The graphic in the BIS Window automatically adapts to show the type of sensor you are using, showing three or four electrodes as required. Each symbol in the graphic represents an electrode and illustrates the most recently-measured impedance status of the electrodes. Although BIS may still be measured when the electrode status is red or yellow, for best performance, all electrodes should be green.

In addition, if the measured electrode-to skin impedance of any electrode or electrode combination is above the limit, or if disconnected electrodes are detected, an INOP will be issued, either BIS HIGH IMPEDANCE or BIS LEAD OFF.
