Abstract
Methods and systems for monitoring to assess the health of a fetus being carried within a mother. The methods include sensing fetal heart information using a fetal heart sensor; determining at least one fetal heart rate measure from the fetal heart rate information; detecting umbilical flow information relating to the flow of blood within the umbilical; deriving at least one umbilical flow indicator from at least the umbilical flow information; and analyzing the fetal heartbeat measure and umbilical flow measure to produce at least one fetal health parameter. The systems include the heartbeat sensor, umbilical flow detector, and a processor which allows analysis of the information obtained from the sensor and detector to provide an indication of fetal health.
