PCT No. PCT/EP91/02020 Sec. 371 Date Jun. 22, 1993 Sec. 102(e) Date Jun. 22, 1993 PCT Filed Oct. 24, 1991 PCT Pub. No. WO93/08534 PCT Pub. Date Apr. 29, 1993.An apparatus for evaluating the fetal condition prior to or under birth receives the signals of a fetal heart rate transducer and a toco transducer. The signals are first preprocessed in the time domain and in the frequency domain. A trace processor identifies possible events like decelerations and contractions. These are validated by a validation processor, whose output is then classified by a classification processor. A score processor scores the events and cooperates with an alarm handler and a reasoning processor. The rules according to which these processors operate are stored in a rule memory and may be edited or selected, or new rules may be set up, by a display or personal computer under control of an expert interface.
