ST waveform analysis for monitoring hypoxic distress in fetal sheep after prolonged umbilical cord occlusion

摘要

IntroductionThe inconclusive clinical results for ST-waveform analysis (STAN) in detecting fetal hypoxemia may be caused by the signal processing of the STAN-device itself. We assessed the performance of a clinical STAN device in signal processing and in detecting hypoxemia in a fetal sheep model exposed to prolonged umbilical cord occlusion (UCO).
