Intended Use

The Cerebra Sleep System is an integrated diagnostic platform that acquires, transmits, analyzes, and displays physiological signals from adult patients, and then provides for scoring (automatic and manual), editing, and generating reports. The system uses polysomnography (PSG) to record the electroencephalogram (EEG), electroculogram (EOG), electrocardiogram (ECG), electromyogram (EMG), accelerometry, acoustic signals, nasal airflow, thoracic and abdomen respiratory effort, pulse rate, and oxyhemoglobin saturation, depending on the sleep study configuration. The Cerebra Sleep System is for prescription use in a home or healthcare facility. The Cerebra Sleep System is intended to be used as a support tool by physicians and PSG technologists to aid in the evaluation and diagnosis of sleep disorders. It is intended to provide sleep-related information that is interpreted by a qualified physician to render findings and/or diagnosis, but it does not directly generate a diagnosis.

Device Story

Cerebra Sleep System is an integrated diagnostic platform for Level 2 PSG and Level 3 HSAT sleep studies. It consists of a Head Mounted Unit (HMU), Chest Mounted Unit (CMU), and Table Top Unit (TTU) for signal acquisition. Inputs include EEG, EOG, ECG, EMG, accelerometry, acoustic signals, nasal airflow, respiratory effort, pulse rate, and SpO2. Data is transmitted wirelessly to the TTU and then to the Cerebra Analytics Suite (CAS) via the Cerebra Portal. CAS provides automated and manual scoring, editing, and report generation. Used in home or clinical settings by physicians and PSG technologists. The system acts as a support tool; a technologist must review and edit data before a physician interprets the final report for diagnosis. Benefits include facilitating sleep disorder evaluation through integrated signal processing and automated scoring.

Clinical Evidence

Prospective clinical validation study with 84 participants (mean age 46.7, BMI 34.5) compared Cerebra Sleep System signals to commercial Level 1 PSG systems (Philips Alice 6, Nihon Kohden PSG-1100). Primary endpoints included TST, AHI, RDI, sleep onset latency, sleep stages, and PLMI. Results showed no statistically significant differences in measured sleep variables, demonstrating signal comparability. Autoscoring validation against consensus manual scoring (138 studies) showed moderate to substantial agreement (Sleep Staging Kappa 0.72, Arousals Kappa 0.48, PLM Index Kappa 0.69, Respiratory Events Kappa 0.54).

Technological Characteristics

Integrated platform with HMU, CMU, and TTU. Materials passed ISO 10993-5 and 10993-10. Connectivity via Wi-Fi, cellular, and Bluetooth. Power via Li-ION/Li-Po batteries. Software-based signal processing and autoscoring. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 60601-2-26, and IEC 60601-2-49. Non-critical device classification for reprocessing.

Indications for Use

Indicated for adult patients undergoing sleep studies in home or healthcare facilities to aid physicians and PSG technologists in the evaluation and diagnosis of sleep disorders.

Regulatory Classification

Identification

#### IV. DEVICE DESCRIPTION

The Cerebra Sleep System is an integrated diagnostic platform that acquires, transmits, analyzes, and displays physiological signals from adult patients, and then provides for scoring (automatic and manual), editing, and generating reports. It is for prescription use in a home or healthcare facility and is used by physicians and polysomnographic (PSG) technologists as a support tool to aid in the evaluation and diagnosis of sleep disorders. A PSG tecnologist must edit, score, and review the data before sleep reports are generated.

The Cerebra Sleep System is capable of collecting data required for Level 2 PSG and Level 3 HSAT studies. A Level 3 HSAT study is a home sleep apnea test with a minimum of 4 channels that include oxygen saturation, electrocardiogram (ECG) or heart rate, airflow (e.g., nasal flow), and respiratory effort (e.g., chest band). A Level 2 PSG study is an unattended sleep test with a minimum of 7 channels that include electroencephalogram (EEG), electrooculogram (EOG), electrocardiogram (ECG) or heart rate, chin electromyogram (EMG), and all signals from Level 3.

Sleep

{4}------------------------------------------------

The Cerebra Sleep System (CSS) is comprised of three main areas:

- Prodigy: This is a PSG recorder capable of performing Level 2 and Level 3 sleep studies. It ● includes the Head Mounted Unit (HMU), which is worn on the patient's head, the Chest Mounted Unit (CMU), which is affixed to a chest effort belt, the Table Top Unit (TTU), which receives data wirelessly, and third party accessories including an oximeter.
- Cerebra Analytics Suite (CAS): The CAS has 4 components Web Processing (for signal ● processing of data), Web Scoring (for generating scoring results, which encompasses autoscoring), Cerebra Viewer (for viewing and editing PSG studies and scoring results) and Web Reporting (for generating reports). A PSG technician must edit, score, and review the data before reports are generated. These components utilize well-defined file formats to enable communication; communication with each component is done through the internet, via the Cerebra Portal.
- Cerebra Portal: All areas of the CSS product are managed by the Portal software. The Portal is used to configure a study on the TTU and allows sleep analysis service providers to manage inventory, patients, and sleep studies. It also configures Prodigy system hardware for an individual sleep study to be performed by a patient.
