The SomniPro PSG RS Plus headbox is a high-end headbox specially designed for most polysomnography studies. It features a full spectrum of EEG channels and EXG channels, covering all body movements. Additionally, it includes an airflow sensor and SpO₂ monitoring. The system can optionally operate wirelessly, with a range of up to 100 metres, extendable to 300 metres. If a patient moves out of wireless range, the headbox continues recording to its internal memory and automatically syncs the backup data once the patient returns within wireless coverage.
