A sleep study worn as a ring
Some home sleep apnea tests use a sensor worn on the finger overnight instead of belts and a nasal cannula. It is still a prescribed test. Whether a ring study is the right test for you is decided after a clinical evaluation.
What the ring measures
A ring-style home test sits on the finger and records signals such as oxygen saturation and pulse overnight. The AASM’s 2017 diagnostic testing guideline already recognised peripheral arterial tonometry with oximetry and actigraphy as a technically adequate technology for home testing in the right patient. It has never endorsed a particular brand.
One FDA-cleared example of this form factor is the Belun Sleep System (510(k) K222579, cleared 23 February 2023), a finger-worn ring used as a home sleep apnea test in adults. That is a description of the device class, not a promise that a specific brand is what you will be given here. The office decides the device after you are evaluated.
It is still a home sleep apnea test
The same rules apply as any other home study. It may be used for uncomplicated adults at increased risk of moderate-to-severe obstructive sleep apnea. It is not appropriate where the guideline requires an in-lab study. A consumer sleep tracker is not a diagnostic test.

Request a ring sleep study
Leave a name, phone and email. Someone from the office will call to confirm whether a ring-style home test is appropriate and to arrange it. Do not describe symptoms in this form. Or ring (614) 898-9340.
