Indications for Use

Sleep Profiler is intended for use for the diagnostic evaluation by a physician to assess sleep quality and score sleep disordered breathing events in adults only. The Sleep Profiler is a software-only device to be used under the supervision of a clinician to analyze physiological signals and automatically score sleep study results; including the staging of sleep, detection of arousals, snoring and sleep disordered breathing events (obstructive apneas, hypopneas and respiratory event related arousals). Central and mixed apneas can be manually marked within the records.

Device Story

Sleep Profiler is a software-only application for analyzing previously recorded physiological signals (EDF files) from Advanced Brain Monitoring X4/X8 systems. It processes inputs including EEG, ECG, EOG, EMG, SpO2, airflow, respiratory effort, and snoring. Automated algorithms perform sleep staging (REM, N1-N3, wake), detect arousals, and identify respiratory events. Used in physician offices, the software generates reports integrating questionnaire data and physiological analysis to assist in OSA diagnosis. Clinicians review and edit automated outputs; manual marking of central/mixed apneas is supported. The device aids clinical decision-making by providing comprehensive sleep metrics, potentially improving diagnostic efficiency for sleep-related breathing disorders.

Clinical Evidence

Clinical validation compared Sleep Profiler auto-scoring against PSG in 60 subjects for AHI detection and 43 subjects for sleep staging. For AHI ≥ 5, sensitivity was 1.00 and specificity 0.85; for AHI ≥ 15, sensitivity was 1.00 and specificity 0.97. Positive likelihood ratios for AHI ≥ 5 and 15 were 6.67 and 33.0, respectively, demonstrating equivalence to the ARES predicate. Staging agreement was evaluated against expert scoring; differences were attributed to inter-rater variability in N1/wake scoring, addressed by a new feature flagging epochs for manual review.

Technological Characteristics

Software-only device; operates on Windows 7/8 desktop or web-portal. Analyzes physiological signals (EEG, ECG, EOG, EMG, SpO2, airflow, respiratory effort). Uses automated algorithms for signal processing, event detection, and sleep staging. Connectivity via USB/Internet. Security controls include administrator privileges, user account rights, and firewall configuration for server access. No hardware components.

Indications for Use

Indicated for diagnostic evaluation of sleep quality and sleep disordered breathing in adults. Used under clinician supervision to analyze physiological signals and automatically score sleep studies, including sleep staging, arousals, snoring, and respiratory events (obstructive apneas, hypopneas, RERAs).

The Sleep Profiler software can analyze any EDF files acquired with the Advanced Brain Monitoring X4 System and the X8 System models SP40 and SP29. Automated algorithms are applied to the raw signals in order to derive additional signals and interpret the raw and derived signal information. The software automates recognition of: - Sleep stages Rapid Eye Movement (REM) and nREM (N1, N2, N3) and wake ● - Heart/pulse rate - Snoring loudness - Sleep/wake - Head movement and position - Snoring, sympathetic, behavioral and cortical arousals - ECG,EOG, EMG waveform - SpOz - Airflow - o Respiratory Effort - Apneas and Hypopneas - Oxygen desaturations. The software identifies and rejects periods with poor electroencephalography signal quality. The full disclosure recording of derived signals and automated analyses can be visually inspected and edited prior to the results being integrated into a sleep study report. Medical and history information can be input from a questionnaire. Responses are analyzed to provide a pre-test probability of Obstructive Sleep Apnea (OSA). The automated analyses of physiological data are integrated with the questionnaire data, medical and history information to provide a comprehensive report. Several report formats are available depending on whether the user has acquired more than one night of data, wishes to obtain a narrative summary report or provide patient reports. The Sleep Profiler software can be used as a stand-alone application for use on Microsoft Windows 7 & 8 operating system platforms (desktop model). Alternatively, the user interface (i.e., entry or editing of information) can be delivered via a web-portal (portal model). The capability to enter or edit patient information, call the application to generate a study report, and/or download a report is provided using either the desktop PC application or web-portal application. The same analysis and report generation software is used for both the desktop and web-portal applications. {5}------------------------------------------------ ## INTENDED USE: Sleep Profiler is intended for use for the diagnostic evaluation by a physician to assess sleep quality and score sleep disordered breathing events in adults only.

Software verification testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The Sleep Profiler software has been thoroughly tested through verification of specifications and system level validation. The results of the verification activities that have been performed demonstrate that the software meets requirements for safety, function, and intended use. SUMMARY OF CLINICAL TESTS: The Sleep Profiler software accuracy was clinically validated with signals acquired with the X8 System concurrent to polysomnography (PSG). The following endpoints were evaluated and met: | Endpoint | The accuracy of the Sleep Profiler-PSG2 software will be equivalent to the predicate device(s): | |----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 | when applied to signals obtained with the FleX8 and compared to PSG to stage sleep. | | 2 | when applied to signals obtained with the FleX8 and PSG, and compared to PSG for detection of sleep disordered breathing for use in diagnosing OSA based on a minimum targeted positive likelihood ratios for an AHI > 5 and 15 are 3.5 and 5.0 respectively. | Where, AHI is the Apnea-Hypopnea Index. The AHI is the number of apnea and hypopnea events per hour of sleep. The results compared auto-detected staging and sleep disordered breathing (i.e., apneahypopnea index) to PSG results obtained by one rater per study. The results confirm Sleep Profiler's positive likelihood ratio for overall AHI vs. PSG is equivalent to the predicate ARES. The Sleep Profiler achieves a positive likelihood ratio for REM AHI vs. PSG REM AHI equivalent to the ARES positive likelihood ratio across all sleep stages. {13}------------------------------------------------ | | ARES | | Sleep Profiler Overall | | Sleep Profiler REM | | |-------------------|---------|----------|------------------------|----------|--------------------|----------| | | AHI ≥ 5 | AHI ≥ 15 | AHI ≥ 5 | AHI ≥ 15 | AHI ≥ 5 | AHI ≥ 15 | | Sample size (n) | 73 | 73 | 60 | 60 | 40 | 40 | | Sensitivity | 0.98 | 0.92 | 1.00 | 1.00 | 0.84 | 0.73 | | Specificity | 0.76 | 0.91 | 0.85 | 0.97 | 0.90 | 0.96 | | Likelihood ratio+ | 4.08 | 10.22 | 6.67 | 33.0 | 8.84 | 18.33 | | Likelihood ratio- | 0.03 | 0.09 | 0.00 | 0.00 | 0.17 | 0.28 | Where likelihood ratio + is the likelihood ratio of a positive test and likelihood ratio – is the likelihood ratio of negative test. The likelihood ratio + is the ratio of the false negative rate (1sensitivity) and true negative rate (specificity); calculated as (1-sensitivity)/specificity. The likelihood ratio – is the ratio of the true positive rate (sensitivity) and false positive rate (1specificity); calculated as sensitivity/(1-specificity) Additionally the Sleep Profiler staging algorithms were compared in a sub-set of subjects (n=43) with at least 4 hours of X8 diagnostic recording time.
