Home sleep testing (HST) is an increasingly popular way to diagnose obstructive sleep apnea and other sleep disorders remotely. As opposed to coming into a sleep lab, the patient is able to self-administer an HST from the comfort of their own home, often at a lower price than in-lab sleep testing. But HSTs also have limitations, including being able to only diagnose sleep apnea and not other sleep disorders, as well as only being clinically appropriate for patients who meet specific pre-test criteria. This comparison guide compares HST devices on parameters including price, rental/leasing options, type, maximum channels, power, chain-of-custody, warranty, dimensions, memory, and recording time.

built-in sensors for snoring, EKG, EMG, and EEG, Bluetooth BLE 5.0 technology extending the battery
life for multinight studies, analysis in Noxturnal Software with artificial intel-
ligence. Indicated for use in patients >2 years old.

Onera’s patch-based no-wire STS system records data from up to four points of contact, maximizing patient comfort. These noninvasive devices, with their intuitive design, are attached within minutes, are easy for patients to use, and save time during hook-up and removal. The user-centric technology offers new opportunities for sleep clinics to expand their programs, and for hospitals that have limited or no access to a sleep clinic to implement sleep diagnostic testing within their institution.
The “auto-on” feature turns on the device as soon as the RIP belt is clicked in place; no need for patients
to push a ‘start’ button. The integrated connection
eliminates the need for an external effort wire set. The “smart guide” sequence guides patients through the setup process and provides
feedback to the patient along the way.
Company provides HST service that includes device shipment, returns, patient support, AI
scoring platform, scoring/inter-
pretation signoff via cloud portal and more. A smartphone app records, measures, and transmits sleep staging, eye movements, oxygen levels, heart rate,
breathing, snoring, EEG, and body position.

The Sunrise Digital Solution is a disposable, single point of contact HSAT consisting of a sensor, smartphone app, and a cloud-based algorithm. Upon completion of the Sunrise sleep study, both mandibular movement (MM) data, anthropometric data, and responses to sleep questionnaires are transferred via wireless connection to the cloud where the Sunrise software, using a dedicated machine learning algorithm, analyzes the data and generates a report available through the Sunrise platform. The MM signal reflects both the respiratory drive and variations in upper airway resistances occurring during SDB.Compact forehead worn unit with up to 3 nights/single report. Voice-prompted alerts. Patient app allows for secure transfer to cloud for real-time quality check and reduced study processing time (optional). Validated automated analysis.
