Abstract
A system and method for performing monitoring of anesthesia and sedation in a patient includes a patient sensor integrating EEG, pulse oximetry, ECG, and AEP signal inputs, integrated analog hardware, digital hardware, and a digital signal processing system that executes a selected algorithm to process received signals representative of a patient's condition, and which generates an index value associated with said patient condition.
Claims48
Apparatus for portable anesthesia and sedation monitoring in a patient, comprising:
- analog hardware for receiving external signals representative of a condition of the patient;
- digital hardware configured for processing said received external signals with at least one software algorithm to generate at least one index value representative of a patient sedation state, said digital hardware further configured with a patient interface;
- and
- a coupling means to operatively couple at least said digital hardware to a display device for providing a visual display of said at least one index value.
An electrode subsystem for incorporation into medical diagnostic equipment utilizing external electrodes to acquire data from a patient, comprising:
- an electrode tracking system for monitoring electrode usage.
A method for acquiring bioelectrical signal data from a patient, comprising:
- placing at least one electrode configured to receive bioelectric signals above a temple of the patient;
- checking signal quality associated with each of said at least one electrodes;
- acquiring bioelectric signals from said patient through said electrode for at least one interval;
- processing the acquired bioelectric signals to generate an index value representative of a condition of the patient;
- and
- displaying said generated index value.
