Wakefulness / sleep differentiation in polygraphy

The lack of sleep information in polygraphy could underestimate the AHI compared to polysomnography, as it is compared with the recording time and not the Total Sleep Time.

 

This is where HypnoLight comes into the picture.

HypnoLighT can differentiate Sleep stage from wakefulness of the patient with a single EEG channel.

So giving an advanced polygraphy where the IAH is based on Total Sleep Time, and therefore a more accurate diagnostic of sleep breathing disorders.

This algorithm, validated through many publications, will provide the sleep information overall the whole recording.


Validated by multiple scientific publications and posters

Presented since 2017 during multiple international congress, the HypnoLighT technology is the result of many years of research and study.

These posters and publications have been approved during prominent events like ERS Praha in 2017, Congrès du Sommeil Nantes 2017, ERS Paris 2018 and CPLF Paris 2018.
