Abstract

Embodiments of the present disclosure disclose a method and system for determining health condition of a subject. First step of the method comprises receiving, by a computing unit, a first oxygen saturation level and a second oxygen saturation level from at least two sensors placed on the subject. Second step of the method comprises determining cerebral extraction of oxygen using the first and second oxygen saturation levels. Third step of the method comprises comparing the cerebral extraction of oxygen with a threshold level. Fourth step of the method comprises identifying a mental fatigue level of the subject based on outcome of the comparison, wherein the mental fatigue level indicates the health condition of the subject.

Claims

1. A method for determining health condition, the method comprising:

receiving, by a health monitoring computing device, a first oxygen saturation level and a second oxygen saturation level from at least two sensors disposed proximate a subject;

determining, by the health monitoring computing device, a level of cerebral extraction of oxygen using the first and second oxygen saturation levels;

comparing, by the health monitoring computing device, the level of cerebral extraction of oxygen with a threshold; and

identifying and outputting, by the health monitoring computing device, a mental fatigue level of the subject based on the comparison, wherein the mental fatigue level indicates the health condition of the subject.

2. The method as claimed in claim 1, wherein the first oxygen saturation level and the second oxygen saturation level are received at a predefined time interval.

3. The method as claimed in claim 1, wherein the level of cerebral extraction of oxygen is determined based on a difference between the first and the second oxygen saturation levels.

4. The method as claimed in claim 1, wherein the first oxygen saturation level is an oxygen saturation level in the incoming blood flow via a carotid artery of the subject and the second oxygen saturation level is an oxygen saturation level in an outgoing blood flow via a jugular vein of the subject.

6. The method as claimed in claim 1, wherein the threshold level is personalized based on at least one of an age of the subject or historical data of a cerebral extraction of oxygen of the subject.

7. A health monitoring computing device, comprising a processor and a memory coupled to the processor which is configured to be capable of executing programmed instructions comprising and stored in the memory to:

receive a first oxygen saturation level and a second oxygen saturation level from at least two sensors disposed proximate a subject;

determine a level of cerebral extraction of oxygen using the first and second oxygen saturation levels;

compare the level of cerebral extraction of oxygen with a threshold; and

identify and output a mental fatigue level of the subject based on the comparison, wherein the mental fatigue level indicates the health condition of the subject.

5. The method as claimed in claim 7, wherein the threshold comprises at least one of a low threshold, a medium threshold level, or a high threshold and the method further comprises generating, by the health monitoring computing device, an alarm if the mental fatigue level is greater than at least one of the medium threshold or the high threshold.

8. The health monitoring computing device as claimed in claim 7, wherein the first oxygen saturation level and the second oxygen saturation level are received at a predefined time interval.

9. The health monitoring computing device as claimed in claim 7, wherein the level of cerebral extraction of oxygen is determined based on a difference between the first and the second oxygen saturation levels.

10. The health monitoring computing device as claimed in claim 7, wherein the first oxygen saturation level is an oxygen saturation level in the incoming blood flow via a carotid artery of the subject and the second oxygen saturation level is an oxygen saturation level in an outgoing blood flow via a jugular vein of the subject.

11. The health monitoring computing device as claimed in claim 7, wherein the threshold comprises at least one of a low threshold, a medium threshold level, or a high threshold and the processor coupled to the memory is further configured to be capable of executing at least one additional programmed instruction comprising and stored in the memory to generate an alarm if the mental fatigue level is greater than at least one of the medium threshold or the high threshold.

12. The health monitoring computing device as claimed in claim 7, wherein the threshold level is personalized based on at least one of an age of the subject or historical data of a cerebral extraction of oxygen of the subject.

13. A non-transitory computer readable medium having stored thereon instructions for determining health condition comprising executable code which when executed by a processor, causes the processor to perform steps comprising:

receiving a first oxygen saturation level and a second oxygen saturation level from at least two sensors disposed proximate a subject;

determining a level of cerebral extraction of oxygen using the first and second oxygen saturation levels;

comparing the level of cerebral extraction of oxygen with a threshold; and

identifying and outputting a mental fatigue level of the subject based on the comparison, wherein the mental fatigue level indicates the health condition of the subject.

14. The non-transitory computer readable medium as claimed in claim 13, wherein the first oxygen saturation level and the second oxygen saturation level are received at a predefined time interval.

15. The non-transitory computer readable medium as claimed in claim 13, wherein the level of cerebral extraction of oxygen is determined based on a difference between the first and the second oxygen saturation levels.

16. The non-transitory computer readable medium as claimed in claim 13, wherein the first oxygen saturation level is an oxygen saturation level in the incoming blood flow via a carotid artery of the subject and the second oxygen saturation level is an oxygen saturation level in an outgoing blood flow via a jugular vein of the subject.
