Sonotrax Pro Fetal Doppler Baby Heart Monitor:
Working Like a Pro
A Review on Edan Sonotrax Pro Fetal Doppler Baby Heart Monitor
The baby’s heartbeat can be monitored anytime after the 10th week of pregnancy. However, it may be difficult to hear the beat before the 12th week. Mothers can continue listening to your baby’s heartbeat right up until their due date.
On How to Use the Sonotrax Pro
Detecting baby’s heartbeat is not always an easy thing, so here are some tips on how to perform a successful exam. Remember, you may not hear baby’s heartbeat on the first try, so remain patient and keep trying.
- Read all instructions included with this fetal doppler. Many fetal dopplers come with an audio recording of a baby’s heartbeat. Listen to this prior to your exam, so you are familiar with how your baby’s heartbeat may sound.
- Turn your fetal doppler on. Check the display to make sure that it’s working.
- Apply lots of ultrasound gel to the face of the doppler’s probe and to your belly. This ultrasound gel will help the doppler glide more easily, and will help pick up your baby’s heart rate.
- Lie down or sit in a comfortable chair.
- Place the doppler probe on your abdomen, just below your belly button but above your pubic bone.
- Begin to move the probe slowly, starting at the middle of your stomach. Rock the probe gently, back and forth, making sure not to miss any part of your belly.
- Be sure to keep the probe in contact with your skin at all times, in order to get the best amplification possible. You may hear static on the machine. If so, apply more ultrasound gel.
On Hearing The Heartbeat
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. If your fetal doppler has a display screen, the number of beats per minute should appear here. If not, count the number of beats you hear in the span of ten seconds, then multiply this number by six. This will give you your baby’s heart rate in beats per minute.
Sometimes the fetal doppler appears to pick up two separate heartbeats. Don’t panic – this does not necessarily mean you are having twins! The way the sound waves reflect off baby’s heart sometimes causes this to occur. Be sure to count the beats of each separate heartbeat; twins will have two different heart rates.
In Case You Can’t Hear the Heartbeat
It is often very difficult to hear your baby’s heart beat using a fetal doppler. If you are early in your pregnancy, the heartbeat may not be strong enough to hear with this machine. Or your baby may simply be in a position that doesn’t allow the doppler to pick up the heart rate. Whatever you do, try not to panic. Perform each test when your bladder is full, so that your uterus is pushed up closer to the face of the doppler. If you still can’t hear the heartbeat, test again later or visit with your health care provider – she can advise you on how to use your doppler.
