Abstract

A system for analyzing medical data is provided for. The system comprises a server adapted to be connected to a communication network for storing medical data, wherein the medical data is generated by a medical device; a session manager for establishing an authenticated session for a user to communicate with the server; and a data manager connected to the session the data manager allowing for storage of said medical data and providing access to previously stored medical data.

Claims

1. A system for analyzing medical data, the system comprising:

a server adapted to be connected to a communication network for storing physiological parameters of a patient over a period of time, wherein the physiological parameters are generated by a medical device, wherein the medical device is a pulse oximeter;

a session manager for establishing a session for a user to communicate with the server;

a data manager connected to the session manager, wherein the data manager allows for storage of the physiological parameters and providing access to previously stored physiological parameters; and

a medical data analyzer connected to the data manager for;

(i) classifying the physiological parameters as one of suitable and unsuitable for analysis;

(ii) analyzing at least one suitable physiological parameter over the period of time to produce analysis results; and

(iii) providing visual representations of the analysis results, wherein the visual representations identify the at least one suitable physiological parameter and at least one unsuitable physiological parameter, wherein the visual representations are based on physiological parameters analysis algorithms.

2. The system as claimed in claim 1, wherein the visual representations may be any combination of graphs, charts, records, tables, and reports.

3. The system as claimed in claim 1, wherein the system may be accessed through a communication network.

4. The system as claimed in claim 3, wherein the communication network is the internet.

5. The system as claimed in claim 1, wherein the system may is adapted to be accessed by patients and medical professionals.

6. The system as claimed in claim 5, wherein the medical data analyzer accepts input from patients and medical professionals when analyzing the physiological parameters.

7. The system as claimed in claim 1, further comprising a computing station adapted to be connected to the medical device.

8. The system as claimed in claim 7, wherein the medical device uploads physiological parameters to the computing station, wherein the computing station then transmits the uploaded physiological parameters to the server.

9. The system as claimed in claim 7, wherein the medical data analyzer is distributed between the computing station and the server.

10. The system as claimed in claim 7, wherein the session manager is distributed between the computing station and the server.

11. A system for analyzing physiological parameters, the system comprising:

a medical device recording physiological parameters from a patient over a period of time;

a computing station, wherein the medical device uploads the physiological parameters to the computing station;

a server connected to a communication network for storing the physiological parameters;

a data manager associated with the medical device for establishing an authenticated session over the communication network with the server to enable the server to control further use of the physiological parameters; and

a medical data analyzer having at least one component associated with the server to allow a medical professional controlled access to the physiological parameters, wherein the medical data analyzer;

classifies the physiological parameters as one of suitable and unsuitable for analysis; and

analyzes at least one suitable physiological parameter over the period of time.

12. The system of claim 11, wherein the medical data analyzer is distributed between the computing station and the server.

13. The system of claim 11, wherein the medical professional requests authentication from the server to have controlled access to the physiological parameters.

14. The system of claim 11, wherein the medical professional may collaborate with one or more other medical professionals to view the physiological parameters.

15. The system of claim 11, wherein the medical data analyzer accepts input from the medical professional when analyzing the physiological parameters.

16. A system for analyzing medical data, the system comprising:

a server adapted to be connected to a communication network for storing physiological parameters of a patient over a period of time, wherein the physiological parameters are generated by a pulse oximeter;

a session manager for establishing a session for a user to communicate with the server;

a data manager connected to the session manager, wherein the data manager allows for;

(i) storage of the physiological parameters, wherein the physiological parameters define at least one desaturation period; and

(ii) access to the physiological parameters previously stored on the server; and

a medical data analyzer connected to the data manager for analyzing the physiological parameters over the period of time, wherein analyzing the physiological parameters comprises;

(i) determining the number of desaturation periods in the period of time; and

(ii) determining the existence of at least one cluster based on the number of desaturation periods.

17. The system of claim 16, wherein determining the number of desaturation periods comprises:

(i) establishing a baseline desaturation level from the physiological parameters;

(ii) detecting a beginning point of a desaturation period when the physiological parameters drop by at least a first predetermined percentage below the baseline desaturation level; and

(iii) detecting an end point of the desaturation period when the physiological parameters rise by at least a second predetermined percentage.
