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.

First claim

We claim:

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 from an external vital-sign monitor into the storage by a communications module where the vital-sign information is associated with the vital-sign monitoring session, wherein the vital-sign information includes vital signs;
determining whether the vital-sign information is quality vital-sign information when there is agreement between two different vital-signs of the vital signs, when the vital-sign information is not quality 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 said 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 pushing 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 a 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. The method according to claim 1 , wherein determining quality vital-sign information further includes determining whether the vital-sign information is substantially free of noise.

8. The method according to claim 1 , further comprising determining reliability of the vital-sign information based on at least one other vital-sign of the vital signs with a reliability module.

9. The method according to claim 8 , further comprising determining reliability of the vital-sign information based on whether the vital-sign information and the at least one other vital-sign is flawed with the reliability module.

10. 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 where the vital-sign information is received from a vital-sign monitor;
determining in substantially real-time from receipt of the vital-sign information by the communications module 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 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 said 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.

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

14. The method according to claim 13 , 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.

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

16. The method according to claim 10 , wherein determining quality vital-sign information includes determining whether the vital-sign information is substantially free of noise and in agreement with at least one other vital-sign of the vital signs.

17. The method according to claim 10 , further comprising determining reliability of the vital-sign information based on a signal from at least one other vital-sign of the vital signs with a reliability module.

18. The method according to claim 17 , wherein determining reliability of the vital-sign information includes determining whether the vital-sign information and the at least one other vital-sign is flawed with the reliability module.
