Benefits of technology

[0007]Depth of consciousness (DOC) is an important physiological assessment during the administration of anesthesia and analgesia drugs. For example, an overdose of anesthesia risks physical impairment or death. An underdose of anesthesia risks “surgical awareness.” A DOC index is typically derived by an EEG sensor measurement of electrical activity in the cerebral cortex. Advantageously, the measurement of various cardio-vas

Embodiment Construction

[0025]FIG. 1 generally illustrates a pharmacological management system 100 having a drug administrator 110 that provides a pharmacological agent 114 to a patient 10 and a pharmacological status monitor 120 responsive to corresponding drug-induced effects 20. Pharmacological agents 114 may be, as examples, anesthesia or analgesia drugs. For anesthesia applications, the desired effect 20 may be general anesthesia or various levels of sedation. The drug administrator 110 may vary from a healthcare provider manually administering drugs to an automatic or semi-automatic machine such as a drug infusion device or medical gas inhalation device. The drug administrator may be responsive to external controls 112, such as manual inputs or electronic signals.

[0026]As shown in FIG. 1, drug-induced effects 20 in the patient 10 may include hypnosis 21, analgesia 23, amnesia 25, paralysis 27 and reflex suppression 29. Hypnosis 21 produces unconsciousness; analgesia 23 blocks the conscious sensation ...

Abstract

A pharmacological management system has sensors, a pharmacological status monitor and a drug administrator. The sensors attach to the patient so as to generate corresponding sensor signals. The pharmacological status monitor is responsive to the sensor signals so as to generate an output indicative of the drug-induced effects of the pharmacological agent on the patient. Further, the monitor output is fed-back to the drug administrator so as to regulate administration of the agent for a desired effect.

Description

PRIORITY CLAIM TO RELATED PROVISIONAL APPLICATIONS[0001]The present application claims priority benefit under 35 U.S.C. §119(e) to U.S. Provisional Patent Application Ser. No. 61 / 243,161, filed Sep. 17, 2009, titled Pharmacological Management System, hereby incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]Generation and analysis of an electroencephalogram (EEG) is a widely accepted noninvasive procedure for diagnosing a person's neurological system. For example, an EEG can reflect changes in a brain's cellular function due to insufficient oxygen or drugs, to name a few. An EEG system consists of a bio-potential sensor and corresponding monitor to process, analyze and display an EEG signal and corresponding neurological parameters. A bio-potential sensor responds to the electrical potential difference between at least two well-spaced electrodes, using a separate ground electrode. The biopotential monitor typically displays the EEG waveform and a numerical index that ...
