EDAN Instruments (300206.SZ) announced that the clinical study The Efficacy of In-Phase and Quadrature Demodulation in Electronic Fetal Heart Rate Monitoring During Labor, facilitated with EDAN F15 Series and its own IQ technology, showed significant improvement in reducing the incidences of fetal heart rate (FHR) doubling and halving when using electronic fetal heart rate monitoring (EFM) with in-phase and quadrature (IQ) demodulation. In comparison between IQ demodlation and conventional demodulation, the former method reduced FHR doubling by approximately 93% and FHR halving by approximately 80% among 225 pregnant women. The study further demonstrated the efficacy of IQ demodulation is more consistent with internal FHR monitoring, partially avoiding the artifact, bringing a safer delivery environment. The device adopted in the study, EDAN F15 Series released 2020, is seen as the next-generation fetal monitor. With its unique IQ intelligent algorithm, UX optimization, and hardware upgradation, F15 Series, according to the EDAN Obstetrics marketing team, will bring a whole new aspect of prenatal solutions.
