Intended Use

The Apnea Risk Evaluation System (ARES™), Model 610 is indicated for use in the diagnostic evaluation by a physician of adult patients with possible sleep apnea. The ARES™ can record and score respiratory events during sleep (e.g., apneas, hypopneas, mixed apneas and flow limiting events). The device is designed for prescription use in home diagnosis of adults with possible sleep-related breathing disorders.

Device Story

ARES Model 610 is a wearable Unicorder for home sleep testing. It records oxygen saturation, pulse rate, snoring, head movement/position, airflow, and forehead physiological signals (EEG). Device monitors signal quality during acquisition, providing voice alerts for adjustments. Data is uploaded via USB to a host computer. ARES Insight software processes raw signals to derive SpO2, pulse, actigraphy, and sleep staging. The system auto-detects obstructive/mixed apneas and hypopneas, predicts pre-test probability of OSA, and assists physicians in identifying candidates for CPAP, oral appliance therapy, or lab-based titration. Benefits include home-based diagnostic convenience for patients with suspected sleep-related breathing disorders.

Clinical Evidence

Clinical evaluation consisted of 20 overnight home sleep studies on 14 subjects. Primary endpoints were comfort and pressure applied to the forehead sensor to confirm that the modified stabilizing strap and enclosure pad (Model 610) provided equivalent signal quality compared to the predicate (Model 600). Results demonstrated equivalent performance.

Technological Characteristics

Battery-powered Unicorder; sensors for SpO2 (red/IR), pulse, snoring, airflow, actigraphy, and EEG. Materials: Santoprene straps, silicone enclosure/forehead pads. Connectivity: USB for data transfer/charging. Memory: Micro-SD. Standards: IEC 60601-1, IEC 60601-1-2, ISO 10993-1, ISO AAMI TIR 30, ISO AAMI TIR 12.

Indications for Use

Indicated for adult patients with possible sleep apnea or sleep-related breathing disorders. For physician-ordered diagnostic evaluation in home settings.

Regulatory Classification

Identification

A breathing (ventilatory) frequency monitor is a device intended to measure or monitor a patient's respiratory rate. The device may provide an audible or visible alarm when the respiratory rate, averaged over time, is outside operator settable alarm limits. This device does not include the apnea monitor classified in § 868.2377.

{1}------------------------------------------------

## DEVICE DESCRIPTION:

The Apnea Risk Evaluation System (ARES™) includes a device called a Unicorder which records oxygen saturation, pulse rate, snoring level, head movement and head position, airflow, and a physiological signal from the forehead used to stage sleep. The battery powered Unicorder provides sufficient capacity to record two nights of data. The device monitors signal quality during acquisition and notifies the user via voice messages when adjustments are required.

A standard USB cable connects the Unicorder to a USB port on a host computer when patient data is to be uploaded or downloaded. The USB cable provides power to the Unicorder during recharging from the host computer or from a USB wall charger. The Unicorder cannot record nor can it be worn by the patient when connected to the host computer or the wall charger.

Software controls the uploading and downloading of data to the Unicorder, processes the sleep study data and generates a sleep study report. The ARES can auto-detect positional and non-positional obstructive and mixed apneas and hypopneas similarly to polysomnography. It can detect sleep/wake and REM and non-REM.

After the sleep study has been completed, data is transferred off the Unicorder is prepared for the next study. The downloaded sleep study record is then processed with the ARES™ Insight software to transform the raw signals and derive and assess changes in oxygen saturation (SpO2), pulse rate, head movement, head position, snoring sounds, airflow, and EEG. The red and IR signals are used to calculate the SpO2 and pulse rate. The actigraphy signals are transformed to obtain head movement and head position.

ARES™ Screener can predict pre-test probability of obstructive sleep apnea (OSA). The ARES can assist the physician to identify patients who will likely have a successful OSA treatment outcome, including CPAP and oral appliance therapies. ARES™ can also help identify patients who would benefit from a laboratory PAP titration.

### INTENDED USE:

The Apnea Risk Evaluation System (ARES™) is indicated for use in the diagnostic evaluation by a physician of adult patients with possible sleep apnea. The ARES™ can record and score respiratory events during sleep (e.g., apneas, hypopneas, mixed apneas and flow limiting events). The device is designed for prescription use in home diagnosis of adults with possible sleep-related breathing disorders.

## TECHNOLOGY:

The Apnea Risk Evaluation System (ARES™), Model 610 uses the same fundamental technology as the ARES™ Model 600. The ARES™ Model 610 is a modified version of the ARES™ Model 600. Modifications have been made to the Unicorder and include use of a USB chip to increase the data transfer speed between the computer and the device, use of micro-SD memory, and a change in interface material between the enclosure and forehead from foam to silicone. Firmware changes were made in association with these hardware changes.

# DETERMINATION OF SUBSTANTIAL EQUIVALENCE:

### COMPARISON TO PREDICATE DEVICES

Additional verification and validation testing confirmed:

- The ARES™ 610 hardware and firmware met the system requirements. .
- All features of the Model 610 were compliance with the system level requirements. .

{3}------------------------------------------------

#### SUMMARY OF CLINICAL TESTS:

Twenty overnight sleep studies were conducted on 14 subjects in the home to confirm the stabilizing strap and enclosure pad for Model 610 provided equivalent signals as compared to the Model 600. Comfort and the pressure applied to the forehead sensor were the measures used in the evaluation. Results demonstrated equivalent performance of the ARES™ Model 610 as compared to Model 600.

### CONCLUSION:

The conclusions drawn from the nonclinical tests demonstrate equivalent performance of the Apnea Risk Evaluation System (ARES™), Model 610 and the legally marketed device, Apnea Risk Evaluation System (ARES™), Model 600. The Apnea Risk Evaluation System (ARES™), Model 610 is substantially equivalent to the predicate device.
