Why patients and doctors choose it
A sleep test you barely notice, with clinically proven accuracy
Most conventional home sleep tests rely on several sensors attached to the body. The Belun Ring needs one ring on your finger, while AI analyses your whole night.
| Conventional home sleep test | Belun Ring | |
|---|---|---|
| What you wear | Usually a nasal cannula, chest and abdominal belts and a finger probe on a cable | One 14-gram ring on your index finger |
| How you sleep | Tubes and belts can shift or pull loose when you turn | On your side, back or front, as you normally sleep |
| What the result is based on | Often the total recording time | Estimated sleep time, with wake, NREM and REM staging |
r = 0.90AHI correlation with in-lab PSG
0.89Accuracy at AHI ≥ 15
0.91 / 0.88Sensitivity / specificity at AHI ≥ 15
0.90REM staging accuracy
84 adults with suspected OSA, concurrent in-lab PSG, AASM 4% rule. Strumpf et al., Sleep Health, 2023. Details and references are in "FDA clearance and clinical evidence" below.
For doctors: the technology inside the ring
Signals
SpO2 and beat-to-beat pulse from a PPG sensor, plus actigraphy, recorded at the base of the index finger to reduce motion artefact.
Analysis
Deep-learning algorithms estimate the AHI (bAHI) and classify wake, NREM and REM sleep (bSTAGES).
Scoring
AHI and ODI are calculated over estimated total sleep time, not total recording time. FDA 510(k) K222579.

For adults aged 22 and over with suspected sleep apnea. Your doctor interprets the result.
Product information
Key features
Deep-learning software turns oxygen, pulse and movement signals into an apnea-hypopnea index and wake, NREM and REM sleep stages.
Sleep with the prepared ring for one night. We collect it the next day.
A sleep test report is included once the recording has been processed.

Frequently asked questions
How does the Belun Ring home sleep test work?
Wear the ring while sleeping at home for one night, following the supplied instructions. We collect it the next day.
Is it the same as an in-lab polysomnogram?
No. A home sleep test is different from a full laboratory polysomnogram. Your clinician can advise which test is appropriate for your symptoms and medical history.
How long do I wear it?
Wear the ring for one night while you sleep, following the supplied instructions.
What happens after the test?
We collect the ring the next day. You receive your sleep test report once the recording has been processed.
Do I need a referral?
Booking requirements can depend on the service pathway. Contact White Aspects if you need help confirming the current process.
Home sleep testing is not a substitute for emergency or acute medical assessment. Seek clinician guidance if symptoms are severe or complex.
FDA clearance and clinical evidence
The Belun Sleep System BLS-100 is FDA 510(k)-cleared (K222579, 23 February 2023) as a Class II device to aid in evaluating moderate to severe sleep-related breathing disorders in adults aged 22 and over, at home or in the clinic, when ordered by a healthcare professional (see the FDA 510(k) summary). The ring records blood-oxygen saturation, pulse and movement; validated deep-learning algorithms estimate the apnea-hypopnea index and sleep stages over estimated sleep time rather than recording time.
In a study of 84 adults wearing the ring during in-lab polysomnography (Strumpf et al., Sleep Health, 2023), accuracy was 0.85, 0.89 and 0.91 at AHI thresholds of 5, 15 and 30, with the Belun AHI correlating with the PSG AHI at r = 0.90. An earlier study of 50 adults (Gu et al., J Clin Sleep Med, 2020) found r = 0.894 for the respiratory event index and 0.85 sensitivity with 0.87 specificity at AHI ≥ 15.
