Intended Use

The Datex-Ohmeda S/5™ BIS Module, E-BIS and accessories are intended to be used with Datex-Ohmeda modular multiparameter monitors for monitoring neurophysiological status of hospitalized patients. The Datex-Ohmeda S/5TM BIS Module, E-BIS and accessories are indicated for monitoring the state of the brain by data acquisition of electroencephalograph (EEG) signals of all hospitalized patients. The Bispectral index (BIS), a processed EEG variable, may be used as an aid in monitoring the effects of certain anesthetic agents. The device is indicated for use by qualified medical personnel only.

Device Description

The Datex-Ohmeda S/5™ BIS Module, E-BIS and accessories is a single-width plug-in parameter module for a Datex-Ohmeda modular monitoring system. The S/5 E-BIS module, M-BIS can be used with the following Datex-Ohmeda modular monitors: S/5 Anesthesia Monitor (AM), S/5 Compact Anesthesia Monitor (CAM), S/5 Critical Care Monitor (CCM) and S/5 Compact Critical Care Monitor (CCCM) with main software L-(C)ANE02(A)..00 or L-(C)ICU02(A)..00 or newer version. The Datex-Ohmeda S/5™ BIS Module, E-BIS and accessories is a parameter module for monitoring the state of the brain by data acquisition of EEG signals of all hospitalized patients. The BIS, a processed EEG variable, may be used as an aid in monitoring the effects of certain anesthetic agents. The Datex-Ohmeda S/5TM BIS Module, E-BIS and its predicate M-BIS (K013389) are used in conjunction with Aspect Medical Systems, Digital Signal Converter-Expanded Performance, DSC-XP (K011534), Patient Interface Cable; PIC (K011534), and BIS Sensor Plus (K994330), BIS Sensor XP (K002734) or BIS Sensor Pediatric (K001980). The raw EEG signal can be displayed from one of the two monitored channels. The waveform size, color and sweep speed can be adjusted. Calculated parameters are: - Bispectral Index,BIS(Range=0-100),continuous processed EEG parameter correlating to the patient's level of hypnosis, where 100=awake and 0=comatose. - Suppression Ratio,SR,(Range=0-100%), the percentage of epochs in the past 63 seconds in which the EEG signal is considered suppressed. - . Electromyograph, EMG, the absolute power (in decibels) in the frequency range 70-110 Hz - Signal Quality Index, SQI (Range:0-100%), the percentage of good epochs in the last 60sec. that could be used to calculate the Bispectral Index and spectral variables. All the calculated parameters can be selected on the display, and trended. Alarms for E-BIS are taken care of by the host monitor and follow the user interface for alarms in Datex-Ohmeda $/5 patient monitors. There are auditory and visual alarms and user adjustable limits for E-BIS. The default is OFF, because it doesn't provide information to be used for treatment or therapy. The BIS Engine at BIS module dictates error messages displayed at Datex-Ohmeda's host monitor's message fields and service page. These error messages are related to the BIS measurement, but follow Datex-Ohmeda user interface rules,

AI/ML (Artificial Intelligence / Machine Learning)

No
The document describes the device as processing EEG signals to calculate specific, defined parameters (Bispectral Index, Suppression Ratio, EMG, Signal Quality Index) using established methods, not through AI/ML algorithms. There is no mention of AI, ML, training data, or complex pattern recognition beyond standard signal processing.

Therapeutic

No.
The device is indicated for monitoring neurophysiological status and brain activity by acquiring and processing EEG signals. It aids in monitoring the effects of anesthetic agents by providing processed variables like the Bispectral Index (BIS), but it does not directly perform any therapeutic action or treatment.

Diagnostic

Yes

The device is explicitly indicated for "monitoring neurophysiological status," "monitoring the state of the brain by data acquisition of electroencephalograph (EEG) signals," and "monitoring the effects of certain anesthetic agents," which are all diagnostic activities. It measures and processes physiological signals (EEG) to provide parameters like Bispectral Index (BIS), correlating to the patient's level of hypnosis.

SaMD (Software as a Medical Device)

The device is described as a "single-width plug-in parameter module" and mentions accessories, indicating it is a hardware component that integrates with a larger monitoring system, not solely software.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

IVDs analyze samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
This device directly monitors physiological signals from the patient's brain (EEG signals) using external sensors. It processes these signals to provide real-time information about the patient's neurological status and the effects of anesthetic agents.

The device's function is to acquire and process electrical signals from the brain, which is a direct physiological measurement, not an analysis of a sample taken from the body.
