How to Use a Fetal Doppler: Steps

1. Before you use your doppler, consider that some women report hearing the heartbeat easier in the morning since that’s when the belly is typically the least bloated. Using the doppler while you have a full bladder can also make the heartbeat easier to hear.
2. To start, lie with your back down on a flat surface. Expose your abdomen like you would during a regular ultrasound.
3. Apply a blob of ultrasound gel or other lubricant to your lower belly. Since the gel will reduce static, use a generous amount.
4. Place the doppler probe in the gel and turn the device on.
5. Starting from your pubic bone, gently glide the probe upwards towards your belly button. Slowly rock the probe, covering every part of your stomach so that you find the fetus.
6. If you hear a heart beat in your earphones and the display shows a heart beat per minute (BPM) of about 120 or higher, you’ve likely found your fetus. Some women say the sound is similar to galloping horses.
7. If after a few minutes you cannot find your baby, shut the device off and try another time. You may need to wait for the baby to grow bigger or switch positions.
8. After you’re finished, clean off the probe to avoid build up. You may choose to wipe it with 70% ethanol and let air dry or simply wipe it with a clean, dry cloth. Do not submerge the device in water (except waterproof models) or apply cleaning chemicals.
