Intended Use
The RemLogic software is intended for Polysomnography studies and allows recording, displaying, and storage of physiological signals to assist in the diagnosis of various sleep related respiratory disorders. The RemLogic software allows: Automated analysis of physiological signals that is intended for use only in adults; An optional audio/visual alert for user defined threshold on calibrated DC input. These alerts are not intended for use as life support such as vital signs monitoring or continuous medical surveillance in intensive care units. Sleep report templates which summarize recorded and scored sleep data using simple measures including count, average, maximum and minimum values as well as data ranges for trended values; The RemLogic software does not provide any diagnostic conclusion about the patient's condition and is intended to be used only by qualified and trained medical practitioners, in research and clinical environments.
Device Story
RemLogic is a Windows-based software application for desktop/laptop computers used by trained medical professionals in clinical/research environments to investigate sleep disorders. It collects/digitizes physiological signals (EEG, EOG, EMG, ECG, airflow, respiratory effort, pulse oximetry, body position, snoring) via external proprietary amplifiers. The software provides tools for real-time acquisition, manual/computer-assisted scoring, and report generation. Computer-assisted analyzers automatically detect respiratory events (apneas, hypopneas), arousals, limb movements, and snoring. Users review these outputs alongside raw data to form clinical diagnostic conclusions. The software does not control life-sustaining functions or deliver energy/drugs. It benefits patients by streamlining the analysis of large volumes of polysomnography data, aiding clinicians in identifying sleep-related respiratory disorders.
Clinical Evidence
Clinical validation study of 51 adult PSG studies (>47,113 epochs). Performance of RemLogic assisted-scoring analyzers compared to a reference standard (majority rule of three expert scorers). Results (Mean PPA/95% CI): Central Apnea (98%/96-99%), Mixed Apnea (98%/96-99%), Obstructive Apnea (94%/91-95%), Hypopnea (86%/83-87%), Arousal (83%/81-85%), Limb Movement (86%/84-88%), Snore (85%/83-88%). False detection rates per hour were also reported. Study concludes RemLogic performance is clinically equivalent to the reference standard and comparable to commercially available predicate devices.
Technological Characteristics
Software-only device; runs on standard Windows desktop/laptop hardware. Digitizes physiological signals via external proprietary amplifiers. Features include real-time acquisition, manual/automated scoring, and report generation. Connectivity: local or remote hard disk storage. No electrical/EMC requirements as it is software-only. Algorithms: rule-based/threshold-based automated event detection for respiratory, arousal, limb movement, and snoring events.
Indications for Use
Indicated for adult patients undergoing polysomnography studies to assist in the diagnosis of sleep disorders and sleep-related respiratory disorders. Not for use as life support or continuous medical surveillance in intensive care units.

#### Description:
#### 1. Overview RemLogic Software
The RemLogic Application is a software product that runs on a desktop or laptop computer and requires no specialized hardware. It is a Windows based application used by trained medical professionals to investigate sleep disorders.
#### 2. Main Functional Areas
The RemLogic application collects and digitizes the electrical voltages of patient physiological signals. After collecting and saving the signals, it provides tools and analyzers to analyze the signals, which aid in the interpretation of a sleep study. The software consists of three main functional areas:
- Acquisition Real time collection of EEG and other physiological . parameters.
{4}------------------------------------------------
Image /page/4/Picture/1 description: The image contains the logo for Natus Neurology. The word "natus" is in a teal color and a sans-serif font. Below that, the word "neurology" is in a smaller, black, italicized font.
- . Scoring & Review - Includes functions providing the user with tools to quickly review PSG studies, either during real time collection of data or after the recordings are complete
- . Reports - Once the digital polysomnography data has been acquired scored and reviewed by both a polysomnographic technologist and a sleep physician the RemLogic software is used to generate a summary report of the sleep study which includes summary statistics of sleep staging describing the patients sleep architecture, summary of sleep events including maximum, minimum counts, indexes, duration, and range based data as well as graphical representations of each (trends). The generated sleep reports are part of the digital polysomnography and the RemLogic software also includes tools to customize report templates to conform to individual sleep center standards/policies and graphic norms.
## 3. Typical work flow using the RemLogic Application software
During the Acquisition phase, the software collects data based on user selected sampling rates, amplifier set-up, and amplifier calibrations. These three factors define how the software collects and displays the data in real-time. The recording is saved on the hard disk of the user's computer in a raw data format. The user can customize displays, observations, event markers, and tags.
## 4. Computer-assisted scoring analyzers
The RemLogic application software contains a number of computer-assisted scoring analyzers. All computer assisted-scoring analyzers are provided to assist trained medical practitioners in the review and analysis of vast amounts of polysomnography data. The computer assisted-scoring analyzers are for analysis of adult patient data only. Each computer-assisted scoring analyzer runs a specific type of event scoring on the patient file. The scoring rule parameters used in the computer-assisted scoring analyzers depend on the montage type associated with the study.
The eight computer-assisted scoring analyzers are:
- Arousal Analyzer
- Respiratory Analyzer
- Limb Movement Analyzer
- Snoring Analyzer
- Desaturation Analyzer
- Heart Rate Analyzer
- · Associations Analyzer
- XactTrace module

## 5. Diagnosis
The RemLogic application software is intended for use by qualified and trained medical practitioners in research and clinical environments, who evaluate the software output with their clinical experience and judgement to provide diagnostic conclusions about the patient's condition. The RemLogic software does not control the delivery of energy, the administration of drugs, or any form of life sustaining function to the patient.
## Indications for Use:

- Automated analysis of physiological signals that is intended for use only in ● adults:
- An optional audio/visual alert for user defined threshold on calibrated DC input. These alerts are not intended for use as life support such as vital signs monitoring or continuous medical surveillance in intensive care units.
- . Sleep report templates which summarize recorded and scored sleep data using simple measures including count, average, maximum and minimum values as well as data ranges for trended values;
- ●
The RemLogic software does not provide any diagnostic conclusions about the patient's condition and is intended to be used only by qualified and trained medical practitioners, in research and clinical environments.
