Abstract

The present invention relates to a method for operating a monitoring system for monitoring physiological data of a patient. For saving power, motion activity data of the patient is obtained and the measurement of physiological data of the patient is initiated, if the motion activity is non-zero and below a selected threshold.

Claims

1. A method for operating a monitoring system for monitoring physiological data of a patient, comprising the steps:

obtaining motion activity data of the patient, and initiating a measurement of physiological data of the patient if the motion activity is non-zero and below a selected threshold.

2. The method according to claim 1, wherein

an ongoing measurement of physiological data is shut down, if the motion activity is above or equal to a selected threshold.

3. The method according to claim 1, wherein

one or more electronic parts of the monitoring system are switched on, if the measurement of physiological data is initiated, and/or one or more electronic parts of the monitoring system are switched off or to stand-by-mode, if the measurement of physiological data is shut down.

4. The method according to claim 1, wherein the method comprises a time schedule scheduling points in time for measurements of physiological data.

5. The method according to claim 4, wherein a scheduled point in time for a measurement of physiological data is alterable within a configurable alteration window enclosing the scheduled point.

6. The method according to claim 5, wherein the length of the alteration window is set automatically or by a person or by a connected system.

7. The method according to claim 4, wherein

a scheduled point in time for a measurement of physiological data is advanced or added, if the motion activity is below a selected threshold, and/or

a scheduled measurement of physiological data is stopped earlier, if the motion activity is below a selected threshold, and/or

a scheduled point in time for a measurement of physiological data is delayed or removed, if the motion activity is above or equal to a selected threshold, and/or

a scheduled point in time for a measurement of physiological data is delayed or removed, if the motion activity is nil.

8. The method according to claim 1, wherein the method comprises the step:

identifying motion situation by comparing the current motion activity characteristics with one or more stored motion activity characteristics.

9. The method according to claim 8, wherein the

the measurement of physiological data of the patient is initiated, if the current motion activity characteristic has a lower motion activity than a stored motion activity characteristic for this motion situation, and/or

an ongoing measurement of physiological data is shut down, if the current motion activity characteristic has a higher motion activity than a stored motion activity characteristic for this motion situation, and/or

a scheduled point in time for a measurement of physiological data is advanced or added, if the current motion activity characteristic has a lower motion activity than a stored motion activity characteristic for this motion situation, and/or

a scheduled measurement of physiological data is stopped earlier, if the current motion activity characteristic has a higher motion activity than a stored motion activity characteristic for this motion situation, and/or

a scheduled point in time for a measurement of physiological data is delayed or removed, if the current motion activity characteristic has a higher motion activity than a stored motion activity characteristic for this motion situation.

10. The method according to claim 1, wherein the measured amount of physiological data is adapted to the motion activity.

11. The method according to claim 1, wherein the method further comprises the steps:

analyzing the measured physiological data, wherein the depth and/or method set of analysis of the measured physiological data or the selection of mathematical or technical methods is adapted to the motion activity.

12. The method according to claim 1, wherein the method further comprises the step:

providing scheduling information to at least one further device.

14. A computer program enabling a processor to carry out the method of claim 1.

15. Use of the method according to claim 1 and/or of the monitoring system and/or of the computer program in a patient monitor for emergency waiting rooms and/or for general ward and/or for rehabilitation and/or for home healthcare and/or for elderly care and/or for physical training, such as

in a pulse oximeter

in a none invasive blood pressure detector,

in a temperature sensor,

in an electroencephalograph,

in a respiration rate detector,

in an uterine contraction detector,

in a fetal ultrasound detector, and/or

in an electrocardiograph.

13. A monitoring system for monitoring physiological data of a patient, comprising

a motion detector configured to sense motion activity of the patient, at least one physiological data detector configured to measure physiological data of the patient and

a controller unit configured to receive motion activity data of the motion detector and to activate the physiological data detector to measure physiological data if the motion activity is non-zero and below a selected threshold.
