Depth of Anesthesia Monitoring (BIS): E-BIS-01 Module (M1127542) and BIS Module (6800-30-50851)
Monitoring the depth of anesthesia is one of the anesthesiologist's key tasks during general anesthesia. Anesthesia that is too light risks intraoperative awareness for the patient; too deep — delayed emergence and increased load on the cardiovascular system. BIS technology (bispectral index) allows the depth of sedation to be assessed objectively from the electroencephalogram.
In this guide we look at two hardware solutions from the BIS line in the MediAccessori catalog: M1127542 (E-BIS-01) — a depth of anesthesia monitoring module with a head box, and 6800-30-50851 — a BIS module. This is practical material for clinics servicing GE monitors and anesthesia machines.
1. What the bispectral index (BIS) is
BIS is a dimensionless index from 0 to 100 that is continuously calculated from electroencephalogram data:
- •100 — the patient is conscious.
- •80–100 — light sedation.
- •60–80 — moderate sedation/anesthesia.
- •40–60 — optimal depth of surgical anesthesia.
- •<40 — deep anesthesia, risk of delayed emergence.
The target range for most operations is 40–60. BIS monitoring is especially indicated for total intravenous anesthesia, when there is no way to judge depth from the concentration of the inhaled anesthetic.
2. How the BIS hardware loop is structured
A typical loop includes:
- Head box — connects to the patient (electrodes/sensors) and transmits the EEG signal.
- BIS module — installed in a slot of the monitor or anesthesia machine, processes the signal and calculates the index.
- Monitor/screen — displays the BIS number and trend.
In our catalog:
- •M1127542 (E-BIS-01) — depth of anesthesia monitoring module with a head box (as stated in the item name: "BIS bispectral index module with head box").
- •6800-30-50851 — BIS module (item "BIS Module").

4. Compatibility table
| PN | Item | Equipment type | Note |
|---|---|---|---|
| M1127542 | E-BIS-01, depth of anesthesia module with head box | monitor / anesthesia machine (BIS-compatible) | check the head box connector |
| 6800-30-50851 | BIS module | monitor / anesthesia machine (module slot) | check the model and slot |
Exact compatibility depends on the platform of your equipment. Before ordering, send us the device model — an engineer will confirm compatibility.
5. How to determine which module is needed
Step 1. Identify the platform The make and model of the patient monitor or anesthesia machine where the BIS will be used.
Step 2. Check the interface Whether there is a free slot for the module, what connector type it is, which head box is required.
Step 3. Verify the PN Match against the nomenclature M1127542 / 6800-30-50851. If in doubt, send a photo of the equipment.
6. Replacement and service
- •After installation, most platforms automatically recognize the module and run self-diagnostics.
- •Complex manual calibration is usually not required, but confirmation of version compatibility by an engineer is a mandatory step.
- •Periodically check the condition of the cables and contacts of the head box.
7. Common mistakes
- •Selection without the equipment model. BIS modules are tied to the platform.
- •Confusion between M1127542 and 6800-30-50851. These are different items (with and without a head box).
- •Ordering without confirming compatibility. Send the model and a photo before payment.
- •Ignoring the software version. Confirm whether the monitor software supports the specific module.
8. Delivery and procurement
MediAccessori supplies GE Healthcare modules (original and compatible) to Russia and the CIS countries:
- •Lead time is confirmed when the order is placed.
- •Rare items: lead time is confirmed when the order is placed.
- •We provide documentation and help with selection by PN.
