User Guide
This guide provides the basic information needed to setup, operate and maintain the UltraPro S100 system.
A PDF copy of this user guide is available on the USB flash drive, Information for Use, provided with your system. Copies of the
user guide may also be accessed at natus.com in the Support section. Scroll to the EMG Product IFUs, select UltraPro S100 and
choose the version for your local language. The files can be printed, saved, or searched using Adobe Reader. A copy of Adobe
Reader can be downloaded directly from Adobe Systems (www.adobe.com). A paper copy of the Instructions for Use in
available languages can be obtained by contacting Natus Technical Support, or by contacting a Natus representative.
Intended Use
The UltraPro S100 is intended for the acquisition, display, analysis, storage, reporting, and management of electrophysiological
information from the human nervous and muscular systems including Nerve Conduction (NCS), Electromyography (EMG), and
Autonomic Responses.
The UltraPro S100 may be used to determine autonomic responses to physiologic stimuli by measuring the change in electrical
resistance between two electrodes (Galvanic Skin Response and Sympathetic Skin Response). Autonomic testing also includes
assessment of RR Interval variability. The UltraPro S100 is used to detect the physiologic function of the nervous system and
to support the diagnosis of neuromuscular disease or condition.
The listed modalities do include overlap in functionality. In general,
•
Nerve Conduction Studies measure the electrical responses of the nerve.
•
Electromyography measures the electrical activity of the muscle.
•
Evoked Potentials (EP) includes Visual Evoked Potentials (VEP), Auditory Evoked Potentials (AEP), and
Somatosensory Evoked Potentials (SEP).
The UltraPro S100 is intended to be used by a qualified healthcare provider.
Clinical Performance
The UltraPro S100 allows the user to perform a wide range of Nerve Conduction Studies (NCS), Electromyography (EMG),
Evoked Potential (EP) Studies and Autonomic Studies as well as Multimodality Programs such as Intraoperative Monitoring
(IOM). Separate software programs and optional accessories allow the user to customize the UltraPro to meet specific clinical
and O.R. monitoring needs.
Clinical Benefits
The UltraPro S100 system assists the physician in collecting measurements and waveforms of the nerves and muscles in the
body to support the diagnosis of neuromuscular disease. Disease is indicated when measurements fall outside of expected or
normative ranges. The UltraPro S100 system facilitates the diagnostic evaluation of diseases such as carpal tunnel,
radiculopathy, nerve lesions, several types of dystrophy, and other diseases of the nervous and muscular system.
