6 Obstetrical exams
Lie down or sit in a comfortable chair.
• Turn on the volume control (1) on the probe. The
LED will turn green.
If the battery is too low, the LED (2) will turn
red.
• Plaster coupling gel (3) onto the surface of the
probe. (Coupling gel can be bought at the local
pharmacy).
• Place the doppler probe on your belly, just below
your navel, but above your pubic bone.
• Begin to move the probe slowly, starting at the
middle of your stomach. Slide the probe gently,
back and forth, making sure not to miss any part
of your belly. The key to the examination is to
intercept the fetal heart with the beam from the
probe. The beam travels in a relatively straight
direction much like a flashlight beam.

Avoid air bubble or air gap between the skin and probe.
To reduce the static on the machine, apply more or less
ultrasound gel. Too much gel can increase the noise level.

Your baby’s heartbeat may sound much faster than you at first
expected. The fetal heartbeat can be anywhere between 120 and
180 beats per minute (bpm). This is much faster than our own
heartbeats. Many women describe their babies heartbeats like the
sound of a galloping horse.
