<P>PROBLEM TO BE SOLVED: To provide a fetal monitoring system which smoothens a process for monitoring the heart rate of a baby who has not born yet, and a fetal monitoring method. <P>SOLUTION: The fetal monitoring system 10 includes: an AECG(Abdominal ElectroCardioGram)/PCG(PhonoCardioGram) sensor 12 which generates an AECG/PCG signal 30 in response to monitoring of a fetal heart; a US(UltraSound) transducer 14 which generates a US signal 32 in response to the monitoring of the fetal heart; and a computer 40 which assess the quality of an AECG/PCG signal 30 and compares the assessed quality of the AECG/PCG signal 30 with a selectable threshold value. The computer 40 is configured to disable the operation of the US transducer 14 and process the AECG/PCG signal 30 to provide a fetal heart rate estimated value as long as the assessed quality of the AECG/PCG signal 30 exceeds the selectable threshold value. The computer 40 is configured to enable the operation of the US transducer 14 and process the US signal 32 to provide a fetal heart rate estimated value only when the assessed quality of the AECG/PCG signal 30 is equal to or less than the selectable threshold. <P>COPYRIGHT: (C)2011,JPO&INPIT |
