Abstract
The present disclosure provides solutions for monitoring the sedation/cognitive state of a patient, such as an Intensive Care Unit (ICU) patient, that can be found in a plurality of sedation/cognitive states, ranging from non-responsive states to fully responsive and providing a selected interaction that is suitable for the determined state in order to optimize the interaction with the patient and, optionally, to improve his/her sedation state. The determination of the sedation state of the patient can be made by one or more sensing devices or input utilities, such as eye tracking sensor, EEG sensor or any applicable user interface.
Claims14
A system for interacting with a patient, comprising:
- a communication module configured to operate in at least three communication modes that comprise:
- (1) unidirectional mode, in which the communication module outputs communication to the patient that does not require his/her response,
- (2) responsive mode, in which the communication module outputs communication to the patient that requires his/her response, the responsive mode comprises questions to or requests from the patient, and
- (3) open communication mode, in which the communication module allows the patient to proactively initiate communication with the system;
- and
- a processing circuitry that comprises an input module configured to receive input data indicative of the patient sedation state, the processing circuitry is configured to:
- i. determine the sedation state of the patient based on the input data;
- and
- ii. trigger the communication module to operate in a selected communication mode in response to the determined sedation state;
- wherein the determination of the sedation state of the patient based on the input data comprises classifying the sedation state of the patient into one of at least three sedation levels, each level triggers one or more level-specific communication modes;
- wherein said classifying comprises scoring the sedation state of the patient, the score defines the sedation level, wherein three ranges of scores define the sedation levels, each range defines a different level;
- and
- wherein the processing circuitry is configured to:
- trigger the unidirectional mode upon determining a non-responsive sedation state of the patient;
- trigger the responsive mode and/or the unidirectional mode upon determining a low-level responsive sedation state of the patient;
- trigger the open communication mode and/or the responsive mode and/or the unidirectional mode upon determining a high-level responsive sedation state of the patient;
- wherein the scoring is a Richmond Agitation-Sedation Scale (RASS) score.

A method for interacting with a patient, comprising:
- receiving and processing input data indicative of the patient sedation state;
- determining based on the input data the sedation state of the patient;
- and
- in response to the determined sedation state of the patient, outputting by a communication module a selected communication in a communication mode selected from at least one of three communication modes that comprises:
- (1) unidirectional mode, in which the communication module outputs communication to the patient that does not require his/her response, (2) responsive mode, in which the communication module outputs communication to the patient that requires his/her response, the responsive mode comprises questions to or requests from the patient, and (3) open communication mode, in which the communication module allows the patient to proactively initiate communication with the system;
- wherein the determination of the sedation state of the patient based on the input data comprises classifying the sedation state of the patient into one of at least three sedation levels, each level triggers one or more level-specific communication modes;
- wherein said classifying comprises scoring the sedation state of the patient, the score defines the sedation level, wherein three ranges of scores define the sedation levels, each range defines a different level;
- wherein said outputting comprises:
- selecting the unidirectional mode upon determining a non-responsive sedation state of the patient;
- selecting the responsive mode and/or the unidirectional mode upon determining a low-level responsive sedation state of the patient;
- selecting the open communication mode and/or the responsive mode and/or the unidirectional mode upon determining a high-level responsive sedation state of the patient;
- wherein the scoring is a Richmond Agitation-Sedation Scale (RASS) score.
