V Series Operating Instructions 19 - 11
Bispectral Index (BIS) (Optional) Measuring BIS
19.3 Measuring BIS
1. Connect the BISx or BISx4 module to the BIS module with the monitor cable.
2. Use the attachment clip to secure the BISx or BISx4 module near, but not above the level of the
patient’s head.
3. Connect the BISx or BISx4 module to the patient interface cable (PIC).
4. Attach the BIS sensor to the patient following the instructions supplied with sensor.
WARNING: The conductive parts of the BIS sensors and connectors should not
come into contact with other conductive parts, including earth ground.
WARNING: To reduce the hazard of burns in the high-frequency surgical neutral
electrode connection, the BIS sensor should not be located between
the surgical site and the electro-surgical unit return electrode.
WARNING: The BIS sensor must not be located between defibrillator pads when a
defibrillator is used on a patient connected to the patient monitor.
WARNING: To reduce the hazard of burns during use of brain-stimulating devices
(e.g. transcranial electrical motor evoked potential), place stimulating
electrodes as far as possible from the BIS sensor and ensure that the
sensor is placed according to package instructions.
NOTE: Make sure the patient’s skin is dry. A wet sensor or a salt bridge could
result in erroneous BIS and impedance values.
5. Turn on the V 12/V 21.
6. Connect the BIS sensor to the interface of the patient interface cable (PIC).
CAUTION: Do not use if the BIS sensor is dry. To avoid dry out, do not open pack
until ready for use. Due to intimate skin contact, reuse may pose risk of
infection. If skin rash or other unusual symptoms develop, stop use and
remove. Limited to short-term use (maximum of 24 hours). Do not cut
sensor components, as this can result in improper operation.
