Method of measuring fetal head orientation, position, and velocity and providing feedback to mother and doctor
First Claim

1. A method of feedback to a mother during labor, comprising:
- measuring fetal descent within a birth canal;
processing, via a data acquisition system, data representing the measured fetal descent to generate substantially continuous fetal descent feedback during a contraction; and
facilitating effective expulsive efforts by providing feedback directly to the mother during the same contraction, wherein the feedback represents the fetal descent feedback.

Abstract
A method is described to provide real-time fetal position, movement velocity, and head orientation feedback to professional medical staff and delivering mothers. Using this feedback, the mother can be apprised of how effective her pushing is moving the baby through the birth canal. Medical staff can use this feedback to assess fetal head orientation and determine location of the baby in the birth canal. The feedback device consists of metrology devices mounted on a fetal scalp electrode, a data acquisition method, software to interpret the metrology signals, and feedback hardware for doctors and the mother.
