5. Spectral Edge Frequency (SEF)
The SEF is the frequency below which 95% of the total power is measured.
6. Total Power (TP)
TP numeric which only monitors the state of the brain indicates the power in the
frequency band 0.5-30Hz. The useful range is 40-100db.
7. Burst Count (BC)
A burst means a period (at least 0.5 second) of EEG activity followed and preceded by
inactivity. The BC numeric helps you quantify suppression by measuring the number of
EEG bursts per minute. This parameter is intended for the BIS module with the Extend
Sensor only.
10.5 Prepare to Measure BIS
1. Connect the BISx model to the BIS module.
2. Use the attachment clip to secure the BISx model near, but not above the level of the
patient’s head.
3. Connect the BISx model to the patient cable.
4. Attach the BIS sensor to the patient following the instructions supplied with sensor.
NOTE
z
Make sure that the patient’s skin is dry. A wet sensor or salt bridge could result in
erroneous BIS and impedance values.
