Amplifier System - reliable, state-of-the-art

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.

The amplifier system provides for patient safety isolation, signal conditioning (physiological signal amplification and filtering), and digitization. A host computer, using TWin software, starts and stops the data transmission and monitors the digitized data.

An intuitive user interface with LCD screen is present with the Base Station. From the Base Station, a user is able to implement such features as electrode impedance checking and amplifier calibration. Also from the LCD display the user is able to obtain information such as connection status to the host computer, and oximetry/pulse rate information when an oximeter is in use.


Wireless Mode
Using wireless Bluetooth® technology, AURA PSG can be used for in-lab and portable 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. Typical polysomnographic signals are conditioned and digitized in the AURA PSG, and then transmitted to the Base Station for real-time data acquisition. Data is stored directly to the computer.

The 8-channel DCM8 DC input module can be connected to the Base Station for a total of 33 recorded channels. Analog signals from devices such as Capnometers, CPAP units, pH Meters, etc, can be connected to the DC input module. This flexibility allows for wide range of physiological parameters to be monitored and recorded.

Ambulatory
AURA PSG can also store 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. Typical polysomnographic signals are conditioned and digitized in the AURA PSG, and then stored directly to the CompactFlash card. The AURA PSG 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 Amplifier System can also be used in a tethered mode. If tethered, no battery is needed as the AURA-PSG is powered by the Base Station and the data is stored to the computer.
