Indications for Use

The HomeSleepTest is a non-invasive prescription device for home use with patients suspected to have sleep disorders including sleep-related breathing disorders. The HomeSleepTest is a diagnostic aid for the detection of sleep-related breathing disorders, sleep staging (REM, N1, N2, N3, Wake), and snoring level. Using three frontal electrodes and one mastoid electrode, the HomeSleepTest records electrical data. In addition, the device records triaxial accelerometer data, ambient light and acoustic data. With help of the ComfortOxyRing, the device records plethysmographic data, as well as SpO2, heart rate and activity data. The HomeSleepTest calculates and reports to clinicians EEG/EOG/EMG, sleep stages, SpO2, plethysmography, pulse rate and snoring level. Based on this, the HomeSleepTest indices derived parameters, such as autonomic arousal (based on plethysmogram of ring), oxygen desaturation index and hypnogram-derived indices, such as time in each sleep stage, as well as other sleep-related parameters, to aid in determining sleep quality and quantity. HomeSleepTest data is not intended to be used as the sole or primary basis for diagnosing any sleep disorders, or sleep-related breathing disorders, prescribing treatment, or determining whether additional diagnostic assessment is warranted. The HomeSleepTest is not intended for use in life-support and monitoring systems. The HomeSleepTest and its accessories are not intended for patients requiring and intensive care. The HomeSleepTest is a prescription device indicated for adult patients aged 21 years and over.

Device Story

Non-invasive, prescription-only home sleep testing device; records 3x frontopolar EEG, 2x EOG, EMG, snoring (via tablet microphone), triaxial accelerometer, ambient light, and head position; uses ComfortOxyRing for plethysmography, SpO2, heart rate, and activity. Patient initializes recording in clinic using device and tablet; tablet app provides video guidance for application and biocalibration. Data recorded via Bluetooth to tablet, then automatically uploaded to HST cloud. Physician accesses data via cloud-based DOMINO software for manual scoring and report generation.

The HomeSleepTest is not intended for use in life-support and monitoring systems. The HomeSleepTest and its accessories are not intended for patients requiring monitoring and intensive care. The HomeSleepTest is a prescription device indicated for adult patients aged 21 years and over. Device Description: The HomeSleepTest is used to record vital signs to determine a hypnogram (sleep profile) and sleep parameters that can be helpful in objectively determining sleep quality and quantity. The HomeSleepTest is available in a standard HomeSleepTest (HST) version and a HomeSleepTest REM+ (HST REM+) version. The only difference between the two basic devices is the measuring point of the outer electrodes on the forehead. HomeSleepTest refers to both versions of the device. Furthermore, the HomeSleepTest can be used to detect the patient's activity, head position and snoring. A recording with the HomeSleepTest is initialized in the clinic/practice. For this purpose, the patient is given the HomeSleepTest and a tablet to take home. The recording can thus be carried out independently in the home environment. Immediately after recording, the data is automatically transferred to the HST cloud. The physician has access to this data via the HST cloud where they can analyze the data via the HST cloud in DOMINO and generate a report. A tablet app with video sequences supports the patient in correct application and guides them through the required biocalibration of the system. Once the test is started, all data from the HomeSleepTest is recorded via Bluetooth. The HomeSleepTest records nine signals (3 x frontopolar EEG, 2 x EOG, EMG, snoring, activity and head position). Snoring and snoring rhythm are recorded via the tablet's microphone. Head position, movement and light support information about time in bed (TIB) and other sleep-related parameters. After completion of the measurement the next morning by the patient, the data is automatically uploaded to the HST cloud where it can be analyzed with help of DOMINO software. After the data has been successfully transferred to the cloud, an exchange with the physician is possible via the feed-back function. It is also possible to release a new {6}------------------------------------------------ measurement for this patient, so that recordings can be made over several nights to capture variability. An overview of all measurements is available to the physician in the HST Cloud. A chat area is used for communication between doctor and patient. In the cloud-based evaluation software, both the pre-evaluation and the raw data of the measurement should be analyzed or edited in an AASM compliant manner. A simple report is available immediately after uploading the measurement. However, the recorded data must still be verified by a physician: for the detailed report (standard report), the measurement is opened in the DOMINO software and scored manually. After evaluation, the standard report is also available in the overview and provides additional information on the various sleep parameters. Performance Testing Summary: Performance testing was conducted to confirm compliance to device specifications. All functions were verified to operate as designed. Signals recorded by the HomeSleepTest underwent performance testing demonstrating that all signal types being recorded comply with the performance criteria set forth by SOMNOmedics. Testing according to ISO 10993 Parts 5 and 10 of the HST Electrode adhesive demonstrated biocompatibility for the intended use; additional direct contact components including the snap fastener cable, ComfortOxyRing and NuPrep skin paste have been tested and are marketed by OEM manufacturers. Basic documentation for software design and validation was provided. Cybersecurity assessment including assessment of impact severity and likelihood were provided.

This confirmed the device is suitable for the intended use. Additionally, a study of 30 adult patients was conducted with a primary objective for the validation of parameters measured with the HomeSleepTest in combination with ComfortOxyRing against the gold standard PSG (SOMNOscreen plus, K201054). This includes parameters regarding sleep stages, oxygen desaturation, pulse rate, snoring, and general parameters. The study was designed as a prospective and open validation study. The measurements of the PSG device and the HST with ComfortOxyRing were evaluated manually according to the current AASM guidelines in random order by a trained and certified scorer. A total of 24563 epochs (excluding epochs with artefacts) from 30 patients were compared. The concordance of the sleep-stages for manually scored epochs is 83.0%, Cohen's kappa is 0.77. The pass criterion of a concordance of 82.0% is achieved. Sleep Parameters were evaluated in a comparative analysis of sleep stages and therefore key sleep parameters performance was compared between PSG and HST. Lights off/on was set equal for both devices based on the video of the PSG recording. Total Sleep Time (TST) measured with PSG and HST showed only minor differences in TST {8}------------------------------------------------ between the devices. The sustained sleep efficiency of 81.85% for PSG and 80.40% for HST showed a difference of 1.45%. Sleep latency, REM latency, Sleep Period Time and Wake After Sleep Onset also showed only minor time differences between the subject and predicate device. Comparison of sleep stages in relation to the parameter of Time in Bed (TIB) were evaluated. Comparison of different sleep stages as % TIB showed that wake, REM, N1, N2, N3 all meet the acceptance criteria of + 10%. Manually scored arousal index for both the subject and predicate devices also met the acceptance criteria. The following oxygen desaturation parameters also met acceptance criteria: - Number of Desaturations total, 90%, and <80% - ODI - Minimal and average SpO2 - Baseline O2 Saturation ● - . SpO2 time<90% - Largest, average and longest desaturation . - Average minimum desaturation ● - . Deepest desaturation, sum of all desaturations - Artifact Comparison of the average pulse rate obtained for PSG and HST demonstrated minimal differences. Snoring parameters including snore number, index, absolute snore and snore for total sleep time met acceptance criteria. General parameters for subject position (upright or not upright) provided comparable results. In the second step the pre-evaluation (automated analysis) of the HST sleep stages is compared to the manually scored measurements of the reference PSG device, A total of 24042 epochs (excluding epochs with artefacts) from 30 patients were compared. The concordance was 53.7%, Cohen's kappa was 0.40. For the pre-evaluation of the HST, the pass criterion of a concordance of 50.0% was achieved. The DOMINO Scorer Manager was used to evaluate the interrater variability. The HST sleep stages were scored by two scorers. The agreement over all 30 HST measurements between scorer 1 and scorer 2 was 71.3%. Therefore, the pass criterion of an agreement above 70.0% was achieved. The results indicate strong consistency between manually-scored PSG and manually-scored HST recordings across key sleep parameters. {9}------------------------------------------------ # Substantial Equivalence Comparison | Features / Technical Information | HomeSleepTest (REM+) Subject device | SOMNOscreen® plus Predicate device | Somfit® by Compumedics Limited Reference device | Discussion of difference/Substantial Equivalence | |-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Product Code | OLV, MNR | OLV, MNR | MNR, OMC | | | K-Number | K240700 | K201054 | K231546 | | | Indications for Use / Intended Use | The HomeSleepTest is a non- invasive prescription device for home use with patients suspected to have sleep disorders including sleep-related breathing disorders.
