sCAVA - Sleep Assessment Using the CAVA Device

Clinical investigation of a medical device (CAVA) for recording eye movements. Forty volunteers will sleep in a specially designed sleep lab for one or two nights, depending on whether they are enrolled onto phase 1 (two nights) or phase 2 (one night) of the study. Each volunteer will wear the CAVA device along with a Polysomnography (PSG) device, which is the gold standard for monitoring sleep. The twenty participants in phase 2 will simultaneously wear a commercially available consumer device for monitoring sleep. The eye movement data captured using CAVA will be processed by novel computer algorithms to classify the sleep stages in the data into Rapid Eye Movement (REM), non-REM and awake. The results will be compared with the ground-truth from the gold standard, and also compared to the results from the commercially available device. The aim of the study is to determine whether CAVA could be a viable and competitive home-monitoring device for analysing sleep.
