Requests for continuous EEG (cEEG) monitoring of ICU patients is causing an increasing workload for EEG teams. The diagnostic utility of EEG for evaluating brain function in critically ill patients has been known for many decades, but only recently has digital EEG technology allowed for broader application of cEEG in the ICU. A large and rapidly expanding body of medical literature documents many areas where cEEG monitoring provides crucial insight into the brain function problems experienced by many critically ill patients. qEEG including automated seizure detection and trending are considered essential tools for managing this workload. Persyst 11 provides an advanced qEEG solution that is seamlessly integrated with the acquisition and review software provided by your EEG manufacturer.
Seizure detection algorithms have advanced a great deal in the last ten years and Persyst 11 is the current state of the art. It has a high detection rate with low false positives. Unlike previous generation products it calibrates automatically and requires no parameterization or settings changes in order to function optimally. Persyst 11 seizure detection begins when acquistion begins.
Persyst 11 is the only seizure detection software that provides a seizure trend. This is a calculation of seizure probability that is displayed in synchronized fashion with the other qEEG trends being calculated.
ICU seizures can be difficult to identify and vary considerably in character. In addition, continuous monitoring is frequently used to look for a wide variety of changes in the patient's EEG. For this reason you need a broad selection of trends, and the ability to customize them as required. Persyst 11 provides a comprehensive set of quantitative trends that can be easily customized to fit your needs.
Electrode Artifact Detection and Rejection
Electrode artifacts can significantly reduce the quality of seizure detection and qEEG calculations. Persyst 11 is the only product that constantly monitors for electrode signal quality. Persyst 11 provides the ability to optionally remove artifact dominated signals from qEEG calculations.
Persyst 11 provides an easy to use electrode quality display to alert medical staff when an electrode has been producing artifact for a significant period of time. Technicians can use this information to decide when to adjust or replace electrodes, which can significantly improve overall recording quality.
EEG Platform Integration
Persyst 11 is completely integrated with the software from your EEG manufacturer. On acquisition there are no extra steps required in order to begin automated detection and trending. During remote monitoring the qEEG trend display is automatically updated and synchronized with the EEG display. On review the qEEG trend display opens automatically and is again synchronized with the EEG display.
Persyst ICU Acquisition Solution
Persyst 11 ICU Continuous Monitoring - Runs on an acquisition station and provides on-line seizure detection and continuous EEG trending. Records are processed as they are being acquired, displaying seizure detections, trends, and storing results for rapid review.
Persyst ICU Review Solution
Persyst 11 Clinical Review - Runs on monitoring or review stations and provides for the review of detections and trends processed on acquisition stations.
