Abstract

A system is disclosed having a storage, a communications module for interacting with a medical measurement device, an analysis controller, and a test module that allows for the testing and evaluating of decision-support algorithms. A method for testing decision-support algorithms is disclosed having the steps of receiving into storage of a ruggedized, compact computer at least one decision-support algorithm; detecting with a communications module the initiation of a vital-sign monitoring session; receiving and storing vital-sign information into storage by the communications module; pushing the stored vital-sign information by an analysis controller to a test module running the stored at least one decision-support algorithm; and providing at least one output from the decision-support algorithm to at least one of a database and a display.

Claims

1. A method for testing decision-support algorithms comprising:

receiving into a storage of a ruggedized, compact computer at least one decision-support algorithm;

receiving and storing vital-sign information associated with a vital-sign monitoring session into the storage by a communications module;

determining whether the vital-sign information is quality vital-sign information, when the vital-sign information is not quality vital-sign information then not using that vital-sign information;

pushing the stored quality vital-sign information by an analysis controller to a test module running the stored at least one decision-support algorithm, wherein pushing includes

retrieving the vital-sign information from the storage, and

converting the vital-sign information into multiple constant-frequency row vectors; and

providing at least one output from the decision-support algorithm to at least one of a database and a display.

2. The method according to claim 1, further comprising receiving the decision-support algorithm into the test module.

3. The method according to claim 1, wherein converting includes shifting data contained in the vital-sign information to leave gaps representing missing data.

4. The method according to claim 1, wherein the storage includes capacity for storing a plurality of decision-support algorithms, and

the storage allows for quick exchange of stored decision-support algorithms.

5. The method according to claim 1, further comprising detecting with the communications module an initiation of the vital-sign monitoring session.

6. The method according to claim 5, further comprising determining when the vital-sign monitoring session has ended based on at least one of a vital-sign being less than a predetermined vital-sign threshold and a signal representing an end of the vital-sign monitoring session received from a source of the vital-sign information, and

wherein detecting the initiation of the vital-sign monitoring is based on at least one of a vital-sign being above the predetermined vital-sign threshold and a signal representing a start of the vital-sign monitoring session received from the source of the vital-sign information.

7. A method for testing decision-support algorithms comprising:

receiving into a storage of a ruggedized, compact computer at least one decision-support algorithm;

receiving and storing vital-sign information associated with the vital-sign monitoring session into the storage by a communications module;

detecting with the communications module an initiation of a vital-sign monitoring session;

determining whether the vital-sign information is quality vital-sign information, when the vital-sign information is not quality vital-sign information then not using that vital-sign information;

pushing the stored quality vital-sign information by an analysis controller to a test module running the stored at least one decision-support algorithm;

providing at least one output from the decision-support algorithm to at least one of a database and a display; and

detecting when the vital-sign monitoring session terminates based on a received heart beats per minute being less than 10 heart beats per minute for a predetermined time threshold, and

wherein detecting the initiation of the vital-sign monitoring includes detecting a heart beat per minute in excess of 10 heart beats per minute.

8. A method for testing decision-support algorithms comprising:

receiving into a storage of a computer at least one decision-support algorithm;

receiving and storing vital-sign information associated with a vital-sign monitoring session into the storage by a communications module;

pushing the stored vital-sign information by an analysis controller to a test module running at least one of the stored at least one decision-support algorithm, wherein pushing includes

retrieving the vital-sign information from the storage, and

converting the vital-sign information into multiple constant-frequency row vectors; and

providing at least one output from the decision-support algorithm to at least one of a database and a display.

9. The method according to claim 8, wherein converting includes shifting data contained in the vital-sign information to leave gaps representing missing data.

10. The method according to claim 8,

where the vital-sign information is received by the communications module from a vital-sign monitor;

and

wherein the computer is ruggedized and compact.

11. The method according to claim 10, further comprising loading at least one decision-support algorithm into the test module.

12. The method according to claim 10, wherein converting includes shifting data contained in the vital-sign information to leave gaps representing missing data.

13. The method according to claim 10, further comprising determining whether the vital-sign information is quality vital-sign information, when the vital-sign information is not quality vital-sign information then not using that vital-sign information.

14. The method according to claim 10, further comprising detecting with the communications module an initiation of the vital-sign monitoring session.

15. The method according to claim 14, further comprising determining when the vital-sign monitoring session has ended based on at least one of a vital-sign being less than a predetermined vital-sign threshold and a signal representing an end of the vital-sign monitoring session received from the vital-sign monitor, and

wherein detecting the initiation of the vital-sign monitoring is based on at least one of a vital-sign being above the predetermined vital-sign threshold and a signal representing a start of the vital-sign monitoring session received from the vital-sign monitor.

16. The method according to claim 8, further comprising detecting with the communications module an initiation of the vital-sign monitoring session.

17. The method according to claim 16, further comprising determining when the vital-sign monitoring session has ended based on at least one of a vital-sign being less than a predetermined vital-sign threshold and a signal representing an end of the vital-sign monitoring session received from a source of the vital-sign information, and

wherein detecting the initiation of the vital-sign monitoring is based on at least one of a vital-sign being above the predetermined vital-sign threshold and a signal representing a start of the vital-sign monitoring session received from the source of the vital-sign information.
