Chapter 7 Fetal Monitoring 

WARNING

1  The monitor is not intended for use in intensive care units (ICU), operating rooms or 

for home use. 

2  Do not apply the monitor during electro-surgery or MRI; otherwise it might result in 

harming the patient or the operator. 

3  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. These 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 the 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 obstetric ultrasonography. 

7.2 Monitoring FHR with Ultrasound 

The ultrasound monitoring is a method to obtain FHR on maternal abdominal wall. Place a US 

transducer (Ultrasound transducer) on maternal abdomen. It transmits low energy ultrasound 

wave to the fetal heart, and receives the echo signal. 

WARNING

Make sure you have confirmed the fetal life by other means before using this monitor for 

FHR monitoring.
