What’s the Nox SAS? Research Sheds Light on a New Way to Record Physiological Signals During Sleep 

03.06.2024

A late breaking research abstract from Nox Medical was recently presented at SLEEP 2024 on the accuracy of a new and simplified way to record the typical physiological signals during sleep.

The Nox SAS, used with the Nox A1s, features a reduced frontal montage that is placed on the patient’s forehead and around the eyes. Since the electrode placements are below the hairline, it does not require the same level of expertise to place the electrodes.

“The Nox SAS reduces the complexity of collecting direct measurements of sleep in the hospital or at home,” says Jón S. Ágústsson, Nox Medical’s VP of AI and Data Science.

Nox Research recently presented a poster on a late breaking abstract at the SLEEP conference in Houston that compares manual sleep stage and arousal scoring using the reduced frontal montage from the Nox SAS solution to conventional polysomnography (PSG). 

According to the abstract, sleep and arousal scoring using the Nox SAS showed a high level of agreement with conventional PSG, consistent with usual levels of interscorer agreement reported for these tasks. 

The Nox SAS solution may therefore be a suitable alternative to PSG for measuring sleep stages and arousals, which can also be used in a real-world sleep environment to offer more accurate estimates of downstream parameters, like the apnea hypopnea index (AHI). 

A flexible solution, the Nox SAS is a head cable with frontal electroencephalography (EEG), electromyography (EMG) and electrooculography (EOG), plus a body cable with bilateral electrocardiogram (ECG) and leg electromyography (EMG) channels. The Nox SAS functions in partnership with the Nox A1s Recorder, which also records RIP, cannula flow, oximetry, and body position. 

The Nox SAS can be applied for a reduced montage PSG sleep study in the sleep lab or at the patient’s home. The setup of the Nox SAS solution is simplified to save time and reduce the potential burden on sleep clinic staff, or to allow patients to self-apply the PSG setup in the comfort of their own homes.
