When it comes to fetal monitoring, mothers with high Body Mass Index (BMI) can be difficult to monitor using conventional ultrasound technology. However, according to a recent study, accuracy and reliability of fetal heart rate monitoring using abdominal fetal electrocardiogram were unaffected by maternal obesity [1]. Designed with electrode technology, the OB solution offers all expectant mothers, including women with high BMI, more mobility with the Avalon beltless solution, which enables clinicians to continuously monitor both fetal and maternal heart rates and uterine activity.
