Abstract

A method and apparatus for evaluating labor progress during childbirth for an obstetrics patient are provided. A set of information data elements associated to an obstetrics patient are received, the set of information data elements including a cervical dilation measure and a level of descent indicator. The set of information data elements is processed to generate labor progress information associated to the obstetrics patient. The labor progress information conveys whether the level of descent indicator is within an expected range of levels of descent corresponding to the cervical dilation measure. A signal for causing the labor progress information to be provided to a user is then released.

Claims

1. An apparatus for monitoring an obstetrics patient during childbirth, said apparatus comprising:

a) an input for receiving a set of information data elements associated with the obstetrics patient, the set of information data elements conveying;

i. a cervical dilation measure; and

ii. an observed level of descent indicator;

b) a processing unit in communication with said input, said processing unit being programmed for;

i. deriving an expected range of levels of descent at least in part by processing the cervical dilation measure, the derived expected range of levels of descent conveying levels of descent expected when childbirth is progressing normally;

ii. causing labor progress information associated with the obstetrics patient to be displayed on a display device, the labor progress information conveying whether the observed level of descent indicator lies within the derived expected range of levels of descent.

2. An apparatus as defined in claim 1, wherein the labor progress information conveys the observed level of descent indicator in relation to the expected range of levels of descent.

3. An apparatus as defined in claim 2, wherein the cervical dilation measure is an expected cervical dilation measure associated with the obstetrics patient.

4. An apparatus as defined in claim 3, wherein said processing unit is programmed for processing the observed level of descent indicator to determine whether it lies within the expected range of levels of descent.

5. An apparatus as defined in claim 1, wherein the labor progress information is caused to be conveyed in graphical format.

6. An apparatus as defined in claim 5, wherein the graphical format includes a chart having a horizontal axis and a vertical axis, the horizontal axis being associated with time and the vertical axis being associated with levels of descent.

7. An apparatus as defined in claim 2, wherein the cervical dilation measure is an observed cervical dilation measure associated with the obstetrics patient.

8. An apparatus as defined in claim 7, wherein said apparatus includes a memory unit for storing a plurality of ranges of levels of descent, each range of levels of descent corresponding to a respective cervical dilation, said processing unit being programmed for causing the plurality of ranges of levels of descent to be conveyed to a user.

9. An apparatus as defined in claim 8, wherein the plurality of ranges of levels of descent conveys a reference band of expected levels of descent derived from data associated with a reference population.

10. An apparatus as defined in claim 7, wherein the labor progress information is caused to be provided in graphical format.

11. An apparatus as defined in claim 10, wherein the graphical format includes a chart having a horizontal axis and a vertical axis, the horizontal axis being associated with cervical dilation measures and the vertical axis being associated with levels of descent.

12. An apparatus as defined in claim 1, wherein said processing unit is programmed for:

a) processing the observed level of descent indicator to determine whether it lies within the derived expected range of levels of descent;

b) generating intervention policy information when the observed level of descent indicator is outside the expected range of levels of descent; and

c) causing the intervention policy information to be provided to a user.

13. An apparatus as defined in claim 1, wherein the labor progress information is caused to be provided in text format.

14. An apparatus as defined in claim 1, wherein the display device is selected from the set consisting of a display screen and a printer.

15. An apparatus for use in monitoring an obstetrics patient during childbirth, said apparatus comprising:

a) an input for receiving a set of information data elements associated with the obstetrics patient, the set of information data elements including a cervical dilation measure;

b) a processing unit in communication with said input, said processing unit being programmed for deriving an expected range of levels of descent at least in part by processing the cervical dilation measure, the derived expected range of levels of descent conveying levels of descent expected when childbirth is progressing normally; and

c) an output for releasing a signal for causing the derived expected range of levels of descent to be conveyed to a user using an output device.

16. An apparatus as defined in claim 15, wherein the derived expected range of levels of descent is caused to be conveyed in graphical format.

17. An apparatus as defined in claim 16, wherein the graphical format includes a chart having a horizontal axis and a vertical axis, the horizontal axis being associated with time and the vertical axis being associated with levels of descent.

18. An apparatus as defined in claim 15, wherein the cervical dilation measure is an observed cervical dilation measure associated with the obstetrics patient.

19. An apparatus as defined in claim 18, wherein said apparatus includes a memory unit for storing a plurality of ranges of levels of descent, each range of levels of descent corresponding to a respective cervical dilation.

20. An apparatus as defined in claim 19, wherein the plurality of ranges of levels of descent conveys a reference band of expected levels of descent derived from data associated with a reference population.

21. An apparatus as defined in claim 15, wherein the derived expected range of levels of descent is caused to be conveyed in text format.

22. An apparatus as defined in claim 15, wherein the output device is selected from the set consisting of a display screen and a printer.
