Introduction

The systems described in this section are diagnostic units designed to provide the medical team with specific information about patient status in the fields of neurology, with the utility of laboratory-based, ambulatory, and long-term electroencephalographic monitoring, and sleep disorder medicine with the application of instrumentation designed to monitor various physiological functions during the night.

The Grass Product Group pioneered the design of both types of instrumentation having designed the first reliable electroencephalographs post World War II, which were later used to study the EEG during the sleep-wake cycle in the 1950s. Indeed, the reliability and economical operation of these early electroencephalographs played a significant role in the advancement of knowledge in these areas.

TWin®, a Windows-based EEG, and PSG software platform is used in most systems including the review stations. A complete line of accessories include printers, video instrumentation for the synchronization of the electrographic data with the patient image, and various sensors and transducers for monitoring physiological signals.

A comprehensive line of clinical systems is marketed under the Grass Technologies trademark. Some of the more popular models covered in this catalog are:
