Additional Information

General Information About Fetal Monitors Fetal Monitoring Fetal monitoring is extensively used in birthing facilities for measuring fetal well being and assessing labor progress. Electronic Fetal Monitors are used to detect and trace the fetal heart rate and uterine contractions. These are usually monitored at the same time however, each one can be obtained separately. Terminology used for Fetal Monitors Ultrasound(U/S Transducer): A transducer is placed on the abdomen to direct an ultrasonic beam towards the fetal heart and to sense Doppler shifted echoes created by moving cardiac structures. Uterine Activity(Toco or U/A Transducer): Uterine contractions are recorded from a pressure-sensitive device that is placed on the abdomen and held by a lightweight stretchable band or belt. Different features in Fetal Monitors Monitoring Modes: Antepartum: occurring or existing before birth; "the prenatal period”. Parameters to be considered: Fetal Heart Rate(U/S) Uterine Activity(U/A) Intrapartum: Occurring during labor and delivery. Parameters to be considered: Fetal ECG Intrauterine Pressure Catheter (IUPC)
