Seizure Detection and Seizure Probability - Persys

Although Persyst 13 displayed the highest sensitivity for seizure count and seizure burden detected, Persyst 11 exhibited the best trade-off between sensitivity and false-positive rate among all seizure detection algorithms Persyst provides advanced trending, spike detection and seizure detection for live or archived CNS Monitor recordings. Combining Persyst with the CNS Monitor offers powerful support for clinicians to monitor and interpret long-term EEG studies Near real-time Seizure Detection and notification can be used as a supplement to patient events and monitoring raw EEG data. Persyst Seizure Detection can reduce the rate of missed seizures during monitoring, potentially reducing patient stays and enhancing safety. Complete review of a 24-hour EEG record can take a considerable amount of time In comparison, the Persyst automated seizure alarm reliably detected both electrographic seizures (76.2% of electrographic seizures) and FIAS/FBTCS (87.2% of FIAS/FBTCS), with a false positive alarm rate (FAR) of .14/hour, or every 7.3 h. 11.4% of all seizures went unrecognized by nursing staff, of which the majority (80.0%) were FIAS Persyst 14 introduces a powerful new set of features including a brand new Seizure Detector written from the ground up, new ways to quantify the extent of change in EEG over time, trending for heart rate and physiological data, and overall optimizations for ease of use, based on feedback from thousands of customers (Thank you!)
