Abstract

A method of performing measurement of a subject comprises measuring a physiological parameter of a subject, deriving data from the measured parameter, optionally, obtaining metadata relating to the measurement of the physiological parameter, determining the quality of the derived data from the derived data and/or the obtained metadata, and if the determined quality matches a predefined criteria, performing a predefined corrective action. In one embodiment, the method further comprises calculating one or more qualifiers from the derived data and/or from the obtained metadata, and wherein the step of determining the quality of the derived data comprises determining the quality of the derived data from the calculated qualifiers.

Claims

1. A method of performing measurement of a subject comprising:

using a measurement device to measure a physiological parameter of a subject, wherein the measurement device further creates metadata,

deriving, by the processor, data from the measured parameter,

receiving, by the processor, the metadata from the measurement device, the metadata comprising information about conditions in which the measurement of the physiological parameter is taken,

calculating, by the processor, one or more qualifiers from the derived data and from the metadata, wherein the one or more qualifiers comprise a stability qualifier that represents the stability of a series of measurements over time, wherein the stability qualifier is calculated using a stability formula,

determining, by the processor, a quality of the derived data from the one or more qualifiers, and

if the determined quality matches a predefined criteria, performing a predefined corrective action;

wherein the corrective action is displayed to the subject via a display.

2. The method according to claim 1, wherein the step of performing a predefined corrective action comprises providing feedback to the subject.

3. The method according to claim 1, wherein the step of performing a predefined corrective action comprises performing a further measurement of the physiological parameter of the subject.

4. The method according to claim 1, wherein the step of performing a predefined corrective action comprises storing a component at a first device measuring the physiological parameter of the subject, the component adapting the future measurement of the physiological parameter of the subject.

5. The method according to claim 1, wherein the metadata comprises information about any one of:

the current time, the subject'"'"'s recent activity, or the number of previous measurements of the physiological parameter of the subject.

6. The method according to claim 1, wherein the stability formula calculates the stability of a single measurement using the standard deviation of the series of measurements.

7. The method according to claim 6, wherein the stability formula calculates a difference between the single measurement and the series of measurements, wherein the difference is divided by the product of a beta value times the standard deviation of the series of measurements, wherein the product of the beta value times the standard deviation defines a threshold, wherein the stability equals zero when the difference exceeds the threshold.

8. The method according to claim 7, further comprising:

manually adjusting the beta value.

9. A system for performing measurement of a subject comprising:

a sensor arranged to measure a physiological parameter of a subject, and to derive data from the measured parameter,

a measurement device arranged to create metadata, the metadata comprising information about the conditions in which the measurement of the physiological parameter is taken, and

a processor arranged to receive the derived data from the sensor and metadata from the measurement device and calculate one or more qualifiers from the derived data and/or from the metadata, wherein the one or more qualifiers comprise a stability qualifier that represents the stability of a series of measurements over time, wherein the stability qualifier is calculated using a stability formula, and determine a quality of the one or more qualifiers, and, if the determined quality matches a predefined criteria, to perform a predefined corrective action.

10. The system according to claim 9, wherein the sensor arranged to measure a physiological parameter of the subject is present in a first device, and the metadata relating to the measurement of the physiological parameter is obtained by a second device.

11. The system according to claim 9 wherein the processor is arranged, when performing a predefined corrective action, to provide feedback to the subject.

12. The system according to claim 9, wherein the processor is arranged, when performing a predefined corrective action, to request performance of a further measurement of the physiological parameter of the subject.

13. The system according to claim 9, wherein the processor is arranged, when performing a predefined corrective action, to create a component for the first device measuring the physiological parameter of the subject, the component adapting the future measurement of the physiological parameter of the subject.

14. The system according to claim 9, wherein the metadata comprises information about any one of:

the current time, the subject'"'"'s recent activity, or the number of previous measurements of the physiological parameters of the subject.
