Publication number: 20160278697Abstract: A method for monitoring anesthetization of a patient, includes the steps of removably connecting a plurality of electrodes to the scalp of the patient and administering sufficient anesthesia to the patient so that the patient attains a plane of anesthesia selected by an operator. The brain waves of the patient are then amplified and digitized after the patient has been anesthetized, before beginning the medical procedure, to obtain a first set of digital data. The brain waves of the patient are then amplified and digitized during the medical procedure to provide a second set of digital data and the first and second sets of digital data are analyzed in at least one of a time domain and a frequency domain. Separate trajectories are then computed from the data analysis trajectories for at least two different indices of an anesthetic state of the patient during the medical procedure, the indices being selected from a group including a Depth Index (DI), a Memory Index (MI) and a Pain Index (PI).Type: ApplicationFiled: June 6, 2016Publication date: September 29, 2016Inventors: Erwin R.

Patent number: 9357965Abstract: Method for determining anesthesia dosage includes following steps. First Interventional Agent (“FIA”) is administered to Patient at a first rate to achieve First Predetermined Plane of Anesthesia (“FPPA”). Brain waves of Patient are analyzed to formulate First Set of Data (“FSD”) corresponding to a self-norm during administration of FIA. First transfer function corresponding to patient biochemical reactions to FIA is computed from FSD. Rate of administration of FIA to Patient is altered by a selected amount after achievement of FPPA for first time required for Patient to deviate from FPPA by predetermined degree. An altered amount of FIA required to cause the predetermined deviation is determined as difference between amount of FIA that would have been delivered to Patient during first time at the first rate and an amount delivered to Patient during the first time at the altered rate. Patient is administered the altered amount of FIA.Type: GrantFiled: January 7, 2013Date of Patent: June 7, 2016Assignee: NEW YORK UNIVERSITYInventors: Erwin R. John, Leslie S. Prichep

Patent number: 8478394Abstract: A device and method for assessment of traumatic brain injury (TBI) is described. The device is configured to acquire brain electrical signals from a patient's forehead using one or more neurological electrodes. The acquired brain electrical activity data is subjected to artifact rejection and feature extraction, and a subset of features are then combined in at least one classifier function.
