Device Description Lifelines iEEG is a software system used to manage and review EEG examinations. It works on data acquired by the Lifelines iEEG acquisition software as well as data from some third party EEG equipment that is imported into the system. The EEG is presented in a conventional way and conventional signal processing is applied such as re-montaging and band pass filtering. The system is also capable of presenting digital video synchronized to the EEG if this is available. Some advanced analysis methods are provided as an aid: FFT analysis and Artifact Removal. The software is designed using service oriented architecture enabling the possibility of reviewing data over WAN without the use of additional remote desktop software solutions. Lifelines iEEG comprises two main software components: The iEEG Centrum client is the main patient and user administration area. It is used to manage patient demographics, keep track of exams and manage user access to clinical data. The system can be configured to allow access from the internet using encrypted communication. The iEEG Review client is used for review and analysis of EEG data by clinical experts. The user can navigate within the EEG that can be many hours long, filter and re-montage as desired. Furthermore, the artifact removal feature can be used to automatically filter artifacts from the EEG. If video data is available, it can be shown synchronized to the EEG traces. Sections of relevance are manually marked by the user and the relevant sections are archived for longterm storage.
Essential Performance The medical device is intended to be used as a tool to aid diagnosis of neurological diseases such as epilepsy. It does not provide life-support functions or monitoring of vital physiological signs. The symptoms to be diagnosed and treated are not acute in the sense that delay in the measurement will not result in harm to the patient. However incorrect output from the device could lead to an inappropriate treatment that would present an unacceptable risk to the patient. Therefore, the Essential Performance of the device is to deliver accurate data in the following ways:
Correct analog processing, analog to digital conversion, digital processing and host communication. Correctly interface to the EEG amplifier and write the data to file. Correctly read the data from the previously written file.
Lifelines iEEG Client User Manual, revision 7.0, Software version 2.3
Correctly process the data according to the specification given by the operator. Correctly display the data according to the specification given by the operator. Associate the data with the correct patient.

Concepts Before delving into the details of each feature of Lifelines iEEG, here is a short description of some of the concepts and terms we will be referring to. Some of these are user interface items you will see as you begin using the software.
Visits Patient Visits are managed automatically by the system. Users cannot specifically add, update or delete visits. When a patient is admitted into the system, a new Visit is created and a new exam is initiated. Subsequent exams are added to the current visit if the user creating or importing them has full access to the visit. Otherwise a new visit is created. A visit is considered completed once all the exams contained in the visit have been archived. If the patient is readmitted after the visit has been closed, a new visit is created. In short, each patient in the database can be associated with more than one visit, and each visit can contain several exams.
Patient Database The Patient Database includes all available patients in the system, past and present plus their demographics. Patients are identified by a distinct Patient ID. The Patient Database is 11
Lifelines iEEG Client User Manual, revision 7.0, Software version 2.3
automatically searched when admitting a patient to the system, when importing an exam, and when reassigning an exam to another patient.
Exams All information and collected data associated with a clinical test make one exam, including reports, external files and workflow state. Each exam is identified by a distinct Exam ID.
Workflow Each exam type is associated with a customizable Workflow, which includes several stages beginning with Initiate and ending with Archive. The Workflow State refers to the step in the workflow that is in progress or most recently completed.
Permissions Permissions are granted to patient visits by user group. Individual users can belong to more than one group. When a user admits a new patient or creates a new exam where a new visit is created, the current user’s default group is given full access to the new visit. Users are only aware of groups they are members of, while administrators have access to all groups.
