Nox A1s offers

Ease-of-use

This ergonomic PSG, with its updated design and responsive user interface, combined with Noxturnal software and mobile app, help make your life and your patients’ lives easier.

Clinical accuracy

Complete polysomnography system, including integrated respiratory inductance plethysmography (RIP) and digital microphone, to provide an accurate score and reliable diagnosis¹.

Efficiency

Equipped with Bluetooth® Low Energy, for stable communication that allows smooth online sleep studies with synchronised video, as well as USB-C and high-resolution RIP technology from Nox for efficient home sleep testing².

Nox SAS: Make polysomnography simple – in hospital and at home

The Nox SAS is an innovative solution for recording EEG, ECG and EMG data via electrodes positioned along the forehead – removing the need for EEG electrodes on the scalp or chin EMGs. This provides patients with the opportunity to have polysomnography tests at home³, with accuracy comparable to a conventional PSG study⁴. Compatible with the Nox A1s system, the setup is simplified to save you time, or to give your patients the ability to run their own setup at home.
