The Positional Sleep Assessment System (PoSAS) provides a simple, inexpensive, and integrated solution to measure the effects of sleeping position on sleep quality, sleep-disordered breathing, and snoring with an array of 29 metrics. 

PoSAS was designed to assist clinicians with identifying patients with positional obstructive sleep apnea (POSA), monitor oral appliance therapy outcomes, and conduct pre-operative OSA screening.

The PoSAS efficacy report provides the calculations and synthesizes the results into four key sleep metrics that enable personalization of non-PAP therapy by identifying which patients would benefit from oral appliance, positional therapy, or the combination of both.
