Polysomnography analyser

Polysomnography analysers are medical devices that monitor multiple physiological signals during sleep to diagnose sleep disorders. They record brain waves (EEG), heart activity (ECG), eye movements (EOG), muscle activity (EMG), breathing patterns, oxygen levels, and sometimes additional metrics like body position or reflux events to assess conditions such as sleep apnoea, insomnia, or restless legs syndrome.

These devices are typically regulated as high-risk medical technology due to their role in clinical diagnosis, though classification varies by jurisdiction. They are often supplied as integrated systems, including hardware (electrodes, sensors) and software for data analysis, and may require specialized training for proper use and interpretation of results.
