Impulse Monitoring to Provide The George Washington University Hospital With Neuromonitoring Services

Columbia, MD – July 27, 2011 – Impulse Monitoring Inc. (IMI), a leading provider of intraoperative neurophysiological monitoring (IONM) services to hospitals, announced today that it has signed an agreement with The George Washington University Hospital, Washington, DC to provide comprehensive IONM services. The agreement includes real-time professional oversight by experienced physicians.

IONM assesses neurological function involving the brain, spinal cord and related nerve structures during such surgeries. Use of IONM facilitates the surgical process and can reduce surgical risk by providing alerts to surgeons of potential harm to the spinal cord or neural structures. “After a rigorous and competitive trial period, Impulse emerged as the clear choice,” said Gregg Brown, OR Manager. “They clearly differentiated themselves in their ability to provide exceptional quality, service and value. By effectively supplementing our own in-house coverage, they enabled GW Hospital to successfully expand our intraoperative monitoring capabilities and serve a greater patient population in the areas of spinal cord and brain surgery.”
