Technology configured to enable determination of sleep apnoea risk factors for subject based on artefacts of time-series eyelid amplitude data collected during conscious state

Abstract

Technology is configured to enable determination of sleep apnea risk factors for a subject based on artifacts of time-series eyelid amplitude data collected during conscious state (i.e., during wakefulness). Risk factors may include a metric representative of a risk that the subject suffers from sleep apnea (e.g., OSA), and in some cases metrics representative of a predicted level of severity associated with that sleep apnea. Embodiments are described by reference to testing technology and methods, which are conducted while a subject is conscious and performing a known task, with eyelid amplitude data collected during testing being processed to extract a plurality of first derivative artifacts that are used for the purposes of sleep apnea risk determinations.
