Monitoring system and method using rules
First Claim
1. 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.

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.
