VentMed Polysomnography PSG Device 22 Channels

Sleep Fairy PSG A-22 is a set of machine for collecting, displaying, storing, and analyzing respiratory and EEG physiological data, which is used to analyze and screen sleep disorder patients. This device uses Windows XP or Windows 7 or above system, with excellent circuit and exquisite appearance design, tight structure, safe and flexible operation.

EEG (Electroencephalography )  is an electrophysiological monitoring method to record the electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp.

1. PSG Application:
