- Sleep-stage detection
Patients with REM-related OSA have lower, or even normal, AHI scores and report milder daytime symptoms, which can lead to misdiagnosis.2
WatchPAT® 300 and WatchPAT® ONE HSATs are powered by breakthrough PAT® technology, which can detect sleep stages and REM sleep apnea.
- True sleep time metrics
When total recording time is used, 20% of cases are misdiagnosed/misclassified.3
With advanced actigraphy that differentiates between wake and sleep periods, WatchPAT® 300 and WatchPAT® ONE use true sleep time to calculate AHI and RDI.
- Insomnia data
Nearly 30% of patients with OSA have insomnia, which is associated with worse treatment outcomes, lower quality of life, and serious health issues.4-6
NEW WatchPAT® with SleePATh® is an advanced, multifunctional app with an in-app questionnaire that evaluates insomnia, as well as daytime sleepiness, sleep scheduling, restless leg syndrome, and patient behavior and lifestyle.
- Central and obstructive sleep apnea differentiation
While OSA is typically treated with CPAP devices or oral appliances, treatment for central sleep apnea may begin by addressing the underlying health cause.7
The Central PLUS module enables WatchPAT® 300 and WatchPAT® ONE to identify central sleep apnea and percent of sleep time with Cheyne-Stokes respiration.
