Defibrillator for strokeResearchers and clinical investigators Medical University of South Carolina (MUSC), Mount Sinai and the University of Tennessee Health Sciences Center reported that patients who had a large-vessel occlusion and used the Cerebrotech Visor could be sent to a comprehensive stroke center that had the capabilities to treat stroke.
The device had better potential of identifying occlusion when compared to standard physical examination that has only shown 40% to 89% accuracy in identifying large-vessel occlusion. Portable and visor-like, the Cerebrotech Visor has shown potential for detecting emergent large-vessel occlusion with 92% accuracy in patients who might have had a stroke.
Cerebrotech Visor is a volumetric impedance phase shift (VIPS) spectroscopy device that sends low energy radio waves through the brain. The radio waves change frequency when passing through fluids. The waves are then able to be reflected back through the brain and be detected by the system’s VIPS device. If a patient is experiencing a severe stroke, the fluid in the brain changes and creates asymmetric radio waves that the Cerebrotech Visor can detect. The more asymmetric the waves are, the more severe of a stroke the patient is experiencing.
The researchers on the study suggest that the device could provide better outcomes following a stroke if emergency medical personnel in the field could use it. The Cerebrotech Visor’s accuracy helps emergency personnel make a decision on where a patient should be taken since it is not necessarily the law to take them directly to a comprehensive stroke center.
