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.

1. A method for implementing a medical system algorithm by an authorized medical caregiver, the steps of the method comprising:

providing a context free grammar to define the medical system algorithm, the grammar comprising non-terminal parameter symbols and terminal parameter symbols that are configured to be satisfied by a plurality of non-terminal medical system parameters and terminal medical system parameters, respectively, the grammar further comprising non-terminal condition symbols and terminal condition symbols that are configured to be satisfied by a plurality of non-terminal medical system conditions and terminal medical system conditions, respectively, the grammar further comprising a response symbol that is configured to be satisfied by a plurality of medical system responses;

receiving a first parameter selection comprising at least of one of the non-terminal parameters or at least one of the terminal parameters, defined by the grammar;

receiving a respective first medical system condition selection corresponding to the at least one of the non-terminal parameter symbol or terminal parameter symbol for the selected first parameter selection defined by the grammar;

receiving a medical system response selection;

generating the medical system algorithm from the first parameter selection, the first medical system condition selection, and the medical system response selection; and

storing the generated medical system algorithm for later use by an automated medical device.

2. The method of claim 1 wherein the first parameter selection comprises at least one of the non-terminal parameter symbols and at least one of the terminal parameter symbols defined by the grammar.

3. The method of claim 1 wherein the response symbol comprises one of a non-terminal response symbol and a terminal response symbol, wherein the response symbol is configured to be satisfied by non-terminal medical system responses and terminal medical system responses, respectively.

4. The method of claim 1 wherein the step of receiving a medical system response comprises receiving a non-terminal medical system response.

5. The method of claim 1 further comprising the steps of:

receiving a second parameter selection comprising at least of one of the non-terminal parameter symbols or at least one of the terminal parameter symbols defined by the grammar; and

,

receiving a respective second medical system condition selection corresponding to the at least one of the non-terminal parameter symbol or terminal parameter symbol for the selected second parameter selection defined by the grammar.

6. The method of claim 5 wherein the second parameter selection comprises at least one of the non-terminal parameter symbols and at least one of the terminal parameter symbols defined by the grammar.

7. The method of claim 5 wherein the first medical system parameter selection is a first alarm selection and wherein the second medical system parameter selection is a second alarm selection, different than the first alarm selection.

8. The method of claim 7 wherein the first alarm selection is for an alarm related to a medical pump function and wherein the second alarm selection is for an alarm related to a patient monitor function.

9. The method of claim 8 wherein the alarm related to the medical pump function is one of a loss of communication with the medical pump alarm and status of medical pump parameter alarm.

10. The method of claim 8 wherein the alarm related to the patient monitor function is one of a loss of communication with the patient monitor alarm and status of a patient monitor parameter alarm.

11. The method of claim 1 wherein the first medical system parameter selection is a first alarm selection.

12. The method of claim 11 wherein the first alarm selection is one of an alarm related to a medical pump function and wherein the second alarm selection is for an alarm related to a patient monitor function.
