Brain monitoring OEM solutions
BIS™ LoC OEM module
<p>The Bispectral Index (BIS™) level of consciousness (LoC) module uses the BIS™ algorithm to process EEG data displayed as the BIS™ index.</p>
Features
BIS™ technology:
- Indicates hypnotic effect through the easy-to-read BIS™ index
The BIS™ LoC two-channel OEM module delivers a full array of BIS™ brain monitoring parameter data, including:
- BIS™ value — 0 to 100
- Signal quality indicatory (SQI) — 0 to 100
- EMG (electromyograph) indicator bar — indicative of muscle activity and other high-frequency artifact
- EEG waveform display — one or two channels of filtered electroencephalogram (EEG) waveforms
- Suppression ratio (SR) — 0% to 100% of time over the last 63-second period that the signal is considered to be in the suppressed state, indicating when an isoelectric (flatline) condition may exist
- Burst count (bursts per minute) — used with BIS™ extended use sensor
- BIS™ trend graph — plots the value of the Bispectral Index™ over time
- Automated BIS™ sensor check — helps provide a faster sensor check
The BIS™ LoC four-channel OEM module system provides all the BIS™ technology performance advantages and clinical benefits, plus additional advanced BIS™ brain monitoring features:
- The ability to acquire and display up to four channels of raw EEG with waveform display, including two channels collected from the right and two channels from the left.
- BIS™ is available for either side of the brain to monitor levels of consciousness, offering both BIS-L and BIS-R values.
- New parameter tools can assess hemispheric differences, including the density spectral array and asymmetry indicator.
- The density spectral array (DSA) provides a graphical representation of a patient’s EEG frequency and power differences between the two brain hemispheres
- The asymmetry (ASYM) indicator is a proprietary BIS™ parameter, in black and white graph form, that provides a simple, quick, and easy-to-assess depiction of hemispheric differences in total power of the EEG between the left and right hemispheres.
Specifications
The following information is provided to the patient monitor by the BISx™ system.
| Bispectral Index (BIS™) | 0 to 100 |

| Signal quality index (SQI) | 0 to 100% |
| Suppression ratio (SR) | 0 to 100% |
| Spectral edge frequency (SEF) | 0.5 to 30.0 Hz |
| Total power | 40 to 100 dB (where 1 μV2 = 40 dB) |
| Burst count | 0 to 30 (with an extend sensor only) |
| EEG (continuous, two-channel, real-time EEG waveform) | |
| EEG scales — two or four channel display | 50 μV/div (+/- 50 μV per waveform) |
| Noise (EEG waveform) | < 0.3 μV RMS (2.0 μV peak-to-peak): 0.25 Hz to 50 Hz |
| BIS™ numeric update frequency | Once per second |
| EEG bandwidth | 0.25 Hz to 100 Hz (-3 dB) +/- 10% |
| Electrode to skin impedances are continuously measured. | |
| Filters | |
| Users can select from a range of low-pass and high-pass filters that are available for artifact rejection. The low-pass filters allow the rejection of muscle artifacts. The high-pass filters allow the rejection of ECG signal interference. In addition, a notch filter suppresses line frequency interference. | |
| The BIS™ XP technology built into the BISx™ system suppresses interference from electrocautery, EMG, and other high frequency noise sources. | |

| Safety specifications | |
The BISx™ system complies with the essential requirements of the Medical Devices Directive 93/42/EEC, as amended by Directive 2007/47/EC, as well as IEC 60601-2 26:2002 and IEC 60601-1-2003. It is a Type BF applied part. It has internal optical coupling and an isolation transformer for patient isolation. It is protected against damage from defibrillation as long as the sensor is not located between the defibrillator pads and is resilient to artifacts from electrosurgery.
