Abstract
A system and method for acquiring and processing abdominal EMG signals from a maternal patient to indicate when a maternal patient should push to progress the labor toward delivery. Raw abdominal EMG signals are acquired and processed in a central unit designed to isolate the patient and any internal circuitry from electrical shock. The central unit has a circuit board that amplifies and filters the EMG signal, then transmits the signal to an A/D converter, after which the digitized signal is transmitted to a computer for further processing and subsequent display of a signal representative of abdominal activity. The system may also acquire and process uterine EMG signals that can be evaluated in conjunction with the abdominal EMG signals.
