Chapter 7 Fetal Monitoring
WARNING :
•
The F9 Monitor is not intended for use in intensive care units (ICU), operating
rooms or for home use.
•
The F9 Monitor is not protected against defibrillation. Do not apply it during
electro-surgery or MRI; otherwise it might result in harming the patient or the
operator.
•
Always check if the alarm settings are appropriate for your patient before starting
monitoring.
7.1 Confirming Fetal Life
Fetal monitoring with ultrasound or DECG can not differentiate a fetal heart rate signal source from
a maternal heart rate source in all situations. Following are some of the signal sources that might be
taken as FHR signal source by mistake:
- High maternal heart rate signal.
- Maternal aorta or other large vessels signals.
- Electrical impulse from the maternal heart transmitted through a recently deceased fetus.
- Movement of a deceased fetus during or following maternal movement.
So you need to confirm fetal life by other means before starting to use the Fetal Monitor, such as
using a fetoscope, stethoscope, Pinard stethoscope or visual obstetric ultrasound.
7.2 Monitoring Fetal Heart Rate (FHR) with Ultrasound
Ultrasound monitoring is a method used to obtain FHR through the maternal abdominal wall, which
can be used for antepartum monitoring. By placing the FHR transducer on the maternal abdomen, it
will transmit a low energy ultrasound wave to the fetal heart, and receive the echo signal.
