BIS Monitor
Q: How do I hook up the
BIS Monitor?
Click
here to see an illustrated example
A: This is a multi-step procedure:
1. Wipe the patient’s forehead off
with alcohol swab
2. Locate the pulse at the site of
the patient’s temple—place the number 3 lead of the BIS strip BELOW this
spot (do not place on pulse, it will throw off the BIS monitor).
3. Place number 4 lead parallel to
pt’s eyebrow
4. Place 1 and 2 leads at a slant on
pt’s forehead
5. Clip the blue rectangular box at
the patient’s bedside; keep it away from any electrical equipment
Q: What does HIGH on the
sensor check mean?
A: A HIGH means that the lead at the indicated
site needs to be moved to a different site on the patient’s forehead. The
number 3 lead is most commonly the one that is high and this is due to
placement at or near the site of the patient’s pulse.
Q: What if I can’t get
the monitor to work after several tries? Should I use a new strip?
A: Never use a new strip. If the monitor
doesn’t work after several tries of moving the leads around on the patient’s
forehead, it means that the patient’s physiology is incompatible with the
monitor. A small portion of patients will have this problem and there is
nothing to be done about it except remove the patient from the study.
Q: What does a hollow
number mean?
A: A hollow number on the monitor means that the
BIS monitor is not getting a “true” read, just an approximate one.
Approximate reads are acceptable for data collection.
Q: How do I do
another sensor check?
A: Find the menu button on the lower right hand
side of the monitor. The button is to the left of the set of up/down
arrows. Press the button. Use the down arrow to scroll to sensor check.
Press the “return button” to the right of the up/down arrows.
