Portables​ polysomnographs

Polysomnography is a non-invasive examination used to diagnose various sleep disorders, such as sleep apnea, insomnia or narcolepsy. More comprehensive than ventilatory polygraphy, it simultaneously records several physiological parameters over the course of a night, which is why it is often performed in laboratories or sleep clinics, although home recording is also possible. The equipment includes :

• Sensors used in ventilatory polygraphy (a nasal cannula, an oximeter, two inductive straps, a brightness sensor, a positioning sensor, a movement sensor, and our PneaVoX sensor).
• Electroencephalograms (EEG) to measure brain activity.
• Electro-oculograms (EOG) to measure eye activity.
• Electromyograms (EMG) to measure muscle activity (chin and legs).
• Electrocardiogram (ECG) to measure muscle activity.

In addition to detecting respiratory abnormalities during sleep, this examination enables us to analyze the different stages of sleep, nocturnal micro-awakenings, movements and cardiac abnormalities. It thus provides elements for diagnosing other disorders, such as pathologies linked to sleep architecture or motor disorders.
