AURA® PSG LITE Ambulatory Sleep Screener

At the heart of all of the AURA PSG systems are Grass designed and manufactured amplifiers. Grass amplifiers are world-renowned in the field of sleep diagnostics for their quality, reliability, simplicity, and serviceability. This unique amplifier is designed with both the sleep Clinician and Researcher in mind. Wireless mode allows for the highest possible patient comfort, while the plethora of channels available are ideal for any ambulatory Sleep Research project. FEATURES • Ambulatory, out-of-lab applications • Tethered, in-lab applications • Use with TWin Companion EKG Holter Software • 16-channels • Built-in Pulse Oximeter • Built-in Electrode/Sensor Connections • Pulse Transit Time (PTT) • Automatic Sleep Report Generation • Compact design that is rugged, lightweight, and easy to wear • Limited Lifetime Warranty on Grass manufactured parts   Use it at home for ambulatory screening and use it in the lab for a full PSG! This powerful, easy-to-use Sleep Screener consists of the high quality 16-channel AURA PSG LITE Amplifier System with built-in electrode/sensor inputs and built-in oximeter designed especially for PSG, and TWin PSG Record and Review Software. The amplifier system provides for patient safety isolation, signal conditioning (physiological signal amplification and filtering) and digitization. Ambulatory AURA PSG stores data directly to a removable CompactFlash® card for out-of-lab sleep diagnostic testing. The lightweight amplifier system is worn by the patient in a comfortable pouch. Electrode and sensor connections are conveniently made directly to the AURA PSG LITE. Typical polysomnographic signals are conditioned and digitized in the AURA PSG LITE, and then stored directly to the CompactFlash card. The AURA PSG LITE can easily be configured to “start up” at a user specified date/time. Data will be recorded from that point forward. When the study is complete, data from the CF card is uploaded via Grass's TWin software. The AURA PSG LITE Amplifier System can also be used in a tethered mode. If tethered, no battery is needed as the AURA PSG LITE is powered by the computer. A host computer, using TWin software, starts and stops the data transmission and monitors the digitized data.
