RestfulSleep utilizes the
Watermark Home Sleep
Study Test known as the ARES
The Apnea Risk Evaluation System
(ARES™) integrates physiological data acquired in-home with clinical
history and anthropomorphic data to determine the presence and
severity of Obstructive Sleep Apnea (OSA). ARES™ has been cleared
for use by the United States Food and Drug Administration (FDA), and
is ISO 13485 certified for Europe and Canada.
ARES™ Home Sleep test Device
A sleep-wearable, wireless
physiological recorder worn on the forehead that acquires and stores
up to 3 nights of nocturnal data. ARES™ measures
blood oxygen saturation (SpO2) and pulse rate (reflectance pulse
oximetry), airflow (by nasal cannula connected to a pressure
transducer), snoring levels (calibrated acoustic microphone), head
movement and head position (accelerometers). When worn in the home,
the ARES™ provides a better profile of the
patient's breathing during sleep in his/her normal environment.
Audio and visual indicators notify the user when the ARES™ requires
adjustment, thus increasing reliability of the device in the home.
The small size of ARES™ allows it to be comfortably
worn in all sleep positions.
A validated predictor of OSA risk
(those in need of a sleep study based on a predicted apnea/hypopnea
index > 5 events/hour) and OSA severity (i.e., minimal, mild,
moderate or severe) using responses to questions about body type,
symptoms of daytime drowsiness, snoring, and other sleep-related
characteristics or health conditions associated with OSA. The
results can be used to rapidly screen large populations to determine
a prior probability of obstructive sleep apnea (OSA). The results
are also used to supplement the physiological data obtained in the
ARES Sleep Apnea Study.
RestfulSleep also utilizes the
Itamar Medical Home Sleep
Study Test known as the WatchPat
