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.

Features:A chest worn device that combines single-channel EEG
sleep staging technology with
traditional respiratory channels to report an AHI based
on EEG-derived sleep time and body position (not just recording time). With one touch controls, multi-night
recordings, and a full-color LED interface, the Synergy is now PAP compatible and
backed by a HIPAA-compliant cloud portal.		Scientifically-validated and
editable autoscored full disclosure signals with foreheadbased self-application. For multinight evaluation of sleep
architecture and sleep continuity in home or hospital,
with auto-detection of sleep
biomarkers associated with
neurodegeneration. PSG2 upgrade enables auto-detection of apneas, hypopneas and RERAs, and REM-related SDB severity.		The AccuSom home sleep
testing device is part
of BioSerenity’s Directto-Patient Home Sleep Testing offering. The level III device and single use
sensors are shipped to
patients and can be used
for up to three nights. Data
transmits directly to be
reviewed and interpreted
by a board-certified sleep
physician.		Local PC software or the
BridgeBuilder Cloud Portal. SDB analysis including RERA, flow limitation, breath
statistics, SpO2 perfusion.
Carrying case, patient instructional video, USB cable. CPAP compatible, multiple nights, immediate report
access, unlimited custom
reports, locking connectors, stainless steel connector, LED study status indicator, all internal biosensors.		Available in three versions: Core (Type 3) and Legacy
(AASM-recommended
parameters), TST (3 x ExG channels). Both devices use
the same sensors recommended for in-lab studies. Connection to the PC (zero-click) automatically
downloads the recording, clears, recharges, and prepares ApneaTrak for the next patient. Uses Easy III PSG software for the scoring and review process.
AASM-compliant HST with “Smart Check” green/red light to indicate if a good study was recorded. Uses a RIP belt, is CPAP compatible, and can collect multinight studies. HIPAA- compliant web portal offers access to studies, scoring, and reports, while facilitating collaboration between local sleep labs and office-based physicians, including IT management and data archival.
Carrying case included, will deliver results while patient is on CPAP, includes video instruction for patient, 24/7 technical support, and analysis, scoring, and reporting software. Designed for basic HST workflow with automated respiratory event analysis and customized reporting. Supports both nasal pressure and thermistor airflow signal.
A fully disposable device based on peripheral arterial tonometry that provides pAHI and TST estimate. Autoscored reports available in the free NightOwl Portal. Smartphone connected. Device in line with AASM guideline requirements. Reimbursable for qualified physicians. Good for up to 14 nights on 1 patient.		A wrist worn device that
provides an automated
analysis based upon 3 points of contact. Within 1-minute post study, raw
data is downloaded and autoscored differentiating
obstructive and central
events, providing an AHI, AHIc, RDI and ODI based upon true sleep time and
sleep staging.		WatchPAT ONE is a fully
disposable HSAT that
does not require return
shipment. As soon as
the study is completed,
sleep data is available
for interpretation. It provides a validated
autoscored report and
raw data for manual
review and editing. The
report differentiates
obstructive and central
events and provides an
AHI, AHIc, RDI, and ODI
based upon TST and
sleep staging.		Scalable multi-night recorder with auto or
timed start options; high
resolution screen with signal display; signal test
features (including impedance measurement),
signal quality/status
information; disposable
and reusable sensors
available; sound recording with optional snap-on
cannula microphone;
RemLogic or Natus SleepWorks for HST recordings included.		DVD included. Connects to
computers via USB. Three options for starting a recording:
immediate, timed, and Smart Start (when patient applies SpO2
probe). Interfaces with Polysmith software or Portable
Nomad software (included). Nomad can use disposable or reusable sensors and probes.		The new Nox T3 has refined Nox RIP technology with
200Hz sampling frequency, which can be used as a primary flow measurement;
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.		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.		Start/stop button, test complete light, signal indicators.
Diagnostic features include
Cheyne-Stokes probability detection and the ability to differentiate between obstructive and central sleep apnea. Data
available via ResMed’s AirView
cloud-based portal to help manage diagnostic reports, interpretations, and prescriptions.		A compact polysomnography type 3 and 4
device powered by one AA battery, the HST Compass contains 2x AC bipolar channels, pressure transducer, integrated RIP interfaces, oximeter, integrated body position
and DC channels—all embedded into a
single module that will comfortably fit on
the chest. Capability to see the traces and
study information right on the screen.		Service includes auto + RPSGT manual scoring, with differentiation
of obstructive and central events. Analyzed indices include count of
apneas, hypopneas, AHI, RDI, REI, CI, ODI, acoustical snoring analysis. Raw data provided in an industry
standard format. Resumable record-
ing and rechargeable battery allow easy multinight testing. Results
based upon analyzed sleep time.		Plug and play with Intelligent
Connect sensors for easy application by the patient at home—programmed or manual start. Extensive
analysis and reporting software (1 license). Charging and data transfer simultaneously via USB. CPAP-compatible recordings. Auto
detection of sleep/wake. Additional
abdomen belt available. Also available: SOMNOtouch RESP eco, a Type III and IV home sleep test.		The first (de novo
clearance Aug
2019) at-home sleep theragnostic that evaluates and auto-
titrates for oral appliance (OA)
therapy. Includes a temporary OA that auto-adjusts in response to real-time respiratory information. Using AI, the data predicts
OA therapy response and target therapeutic position. Tablet-based, cloud-connected, and
operates as a standard HSAT.
