摘要：
summary method for determining at least one maternal physiological parameter in addition to heart rate and respiratory rate； signal monitoring unit； fetal monitoring system； and software module provided for performing the method steps the present invention relates to a method for determining at least one maternal physiological parameter in addition to heart rate and respiratory rate, comprising the following steps: receiving a processed acceleration signal and at least at least one transducer signal corresponding to a fetal heart rate (fhr), at least one transducer signal being provided by at least one transducer (24, 26, 28) provided to record the physiological parameters and convert them to corresponding transducer signals and the processed acceleration signal being provided by at least one signal processing unit (34) provided for processing said transducer signals and said acceleration signal and for evaluating the acceleration signal with respect to at least one of frequency, amplitude, and signal pattern to derive the processed acceleration signal corresponding to at least one maternal physiological parameter, the acceleration signal being acquired by at least one acceleration sensor (30, 32) provided to convert mechanical acceleration in the maternal abdomen (14) to a corresponding acceleration signal, wherein at least one acceleration sensor (30, 32) is different from at least one transducer (24, 26, 28) and wherein at least one acceleration sensor (30, 32), in at least one mode of operation, is rigidly mounted within a bracket ( 20, 22) which at least partially includes at least one transducer (24, 26, 28)； determining and tracking a cross channel check between the processed acceleration signal and at least one transducer signal corresponding to a fetal heart rate (fhr)； and - depending on a cross channel scan result, activating an alert signal (44). 1/2resumo método para determinação de pelo menos um parâmetro fisiológico materno além da frequência cardíaca
