Abstract

A method of monitoring a subject, such as a patient, using rules is provided. The method includes receiving data from the subject, and applying the data to a rule-based algorithm. The method also preferably includes generating a response based on the application of the rule-based algorithm. Some examples of responses include generating an alarm, generating a suggested reason for an identification of an abnormal condition, and generating a suggested response to an abnormal condition that has been identified. Preferably, more than one set of variables is applied to a particular rule-based algorithm. A monitor using the method may be configured to have multiple rule-based algorithms selected and applied simultaneously. Each rule-based algorithm can generate a unique response, or a combination can be used to generate a smaller number of responses. Also, a monitor using this method may be configured to allow rule-based algorithms to be exchanged and/or altered.

Dependent claims

A patient physiologic monitoring assembly comprising:

a plurality of sensors that generate a real-time physiologic data stream, said real-time physiologic data stream including a plurality of physiologic variables;
a first logic rule set for diagnosing a physiological condition of a patient, the first logic rule set including a plurality of logic rules for interpreting the plurality of physiologic variables of the real-time physiologic data stream;
a second logic rule set for diagnosing the physiological condition of the patient, the second logic rule set including a plurality of logic rules for interpreting the physiologic variables of the real-time physiologic data stream;
and
a controller that receives said real-time physiologic data stream as the data stream is generated, said controller including a logic that:
simultaneously cross references said plurality of physiologic variables of the real-time physiologic data stream with the first logic rule set and second logic rule set as the controller receives the real-time physiologic data system;
generates at least a first diagnostic interpretation of said plurality of physiologic variables utilizing said first logic rule set and a second diagnostic interpretation of said plurality of physiologic variables utilizing said second logic rule set;
and
displays said first and second diagnostic interpretations on a display element;
wherein the first diagnostic interpretation and the second diagnostic interpretations are different diagnostic interpretations of the same physiological condition, using the same real-time physiologic data stream.

A method for diagnosing the medical condition of a patient, the method comprising:

acquiring at least one real-time physiological data stream;
identifying, with a logic operating on a controller, a physiological data present in the at least one real-time physiological data stream;
selecting, with the logic, a first rule set comprising rule-based algorithms directed to produce at least one first diagnostic interpretation of the physiological data;
selecting, with the logic, a second rule set comprising rule-based algorithms directed to produce at least one second diagnostic interpretation of the physiological data, wherein the first rule set and the second rule sets produce different diagnostic interpretations of the same identified physiological data;
applying, with the logic the first rule set to the at least one real-time physiological data stream as the at least one real-time physiological data stream is acquired to produce at least one first diagnostic interpretation;
applying, with the logic, the second rule set to the at least one real-time physiological data stream as the at least one real-time physiological data stream is acquired to produce at least one second diagnostic interpretation;
and
displaying at the first and second diagnostic interpretations.
