Abstract

A system and method to configure a rule set used in connection with a medical monitoring system for monitoring patients and patient care equipment, especially medication delivery pumps, based on a variety of conditions and parameters associated with monitored biometric information and equipment information and for providing user-defined responses to those conditions and parameters.

Claims

1. A patient care system comprising:

a plurality of sensors for generating a real-time physiologic condition data stream, the real-time physiologic condition data stream including values for a plurality of different physiologic parameters, associated sensed conditions based upon the real-time physiologic condition data stream, and sensor equipment information;

a medical pump for delivering a medicine to a patient, the medical pump generating a pump equipment information data stream including a plurality of pump conditions and pump operating parameters;

a processor in communication with the plurality of sensors and the medical pump and including a memory and a logic adapted to;

receive the real-time physiological condition data stream including the values for the plurality of different physiologic parameters, the associated sensed conditions, and sensor equipment information;

receive pump equipment information from the medical pump;

receive in the memory a plurality of user customizable medical system algorithms available for selection, each of the medical system algorithms being established by an authorized hospital user and being independently selectable without changing to a different protocol or personality of the medical pump, at least some of the medical system algorithms comprising a user customizable predetermined response based upon at least two parameter/condition pairs connected by a Boolean operator being satisfied;

receive a selection of a medical system algorithm from the plurality of medical system algorithms stored in the memory; and

,

implement the selected medical system algorithm to process the real-time condition data stream and execute the predetermined response if the medical system algorithm is satisfied.

2. The system of claim 1 wherein the processor, memory and logic are further adapted to receive a real-time data stream monitoring session selection for initiating a monitoring session for the real-time data stream including the plurality of physiologic variables.

3. The system of claim 1 wherein the selected medical system algorithm comprises a first condition including at least one of a physiologic variable alarm time duration, a patient drug load, a demand to delivery ratio, a mean drug consumption, and a patient drug factor.

4. The system of claim 1 wherein the selected medical system algorithm comprises a medical system response including at least one of an implementation of another medical system algorithm, an adjustment of a drug delivery rate, a pause to a drug delivery, a call to medical personnel, and a medical diagnosis.

5. The system of claim 1 wherein each medical system algorithm is a rule set established using context free grammar on the processor to define a set of multi-variable inputs that must occur before the predetermined response is executed.

6. The system of claim 5 wherein the predetermined response that is executed includes a plurality of predefined responses selected by the authorized hospital user.
