Somfit is not a full polysomnography: it measures 1 EEG channel, 1 EMG channel and 2 EOG channels. Falcon PSG records 6 differential and 10 referential channels. With Somfit the sleep physician reviews the measurement. Whether a system suits your patient group is stated in the manufacturer’s instructions for use; we discuss this with you beforehand.
