7.2.2 FHR Monitoring Procedure
1) Place the transducer belts across the bed. Lay the patient on the bed and draw the belts over
her abdomen.
2) To acquire the FH signal, search for the location of the fetal heart using a stethoscope or a
fetoscope. Apply ultrasonic gel on the transducer and move it slowly around the abdomen
until a clear heartbeat sound of the fetal heart is heard. Refer to Figure 7-1 for the transducer
position.

3) To secure the Transducer, wrap the abdomen with the belt over the transducer. Secure the
transducer by pushing its buckle through the overlapping section of the belt.
Make sure the belt is neither too tight nor too loose and the patient is monitored comfortably.
When the fetal heart beat sound is detected, the FHR trace and numeric value are displayed
on the screen.
NOTES:
1) Do not mistake high maternal heart rate for fetal heart rate.
2) The best quality records will only be obtained when the transducer is placed in the
optimum position.
3) Positions with strong placental sounds (swishing) or fetal cord pulse (indistinct pulse at
fetal rate) should be avoided.
4) If the fetus is in the cephalic position and the mother is supine, the clearest heart sound
will normally be found on the midline below the umbilicus. During the monitoring,
prolonged lying in the supine position should be avoided due to the possibility of supine
hypotension. Sitting up or lateral positions are preferable and may be more comfortable to
the mother.
5) It is not possible to measure FHR unless an audible fetal heart signal is present. The fetal
pulse can be distinguished from the maternal pulse by feeling the mother’s pulse during
the examination.
