Please do not use a home doppler. Here are just a few reasons why -
The Presence of a heartbeat doesn't mean the baby is well: Parents may be falsely reassured when they hear a heartbeat, when actually their baby could be in distress. This could lead to life-threatening delays in seeking medical assistance. The best indicator of fetal wellbeing is always the baby’s movements
Home dopplers are not microphones: They are not amplifying the sound of your baby’s heartbeat. They are sending ultrasound waves into your body that reflects off moving blood vessels and SIMULATE a sound. There are a lot of blood vessels in a pregnant woman's abdomen, the baby’s heart beating being just one. The placenta also pulses at the same rate as the heart and the mother’s main artery runs across the abdomen and that can also be picked up on a doppler. There are so many vessels that can simulate the same sound as a fetal heart.
Not recommended for professionals, NICE guidelines even highlight the risks to professionals - “Do not rely solely on the CTG trace for fetal wellbeing. Be aware of limitations and artefacts i.e. doubling of the maternal pulse being recorded as the fetal heart.”
Users say they offer bonding, but there are other ways to bond. If siblings or partners want to hear the fetal heart ask your midwife to record it at your next appointment. The risk of using them for ‘fun’ or bonding is the same – hearing a heartbeat is subconsciously reassuring, however much we tell ourselves they won’t be used for reassurance.
The NHS, The Royal College of Midwives and even the FDA (Food and Drug Administration in America) all warn of their dangers. The NHS choices website says home foetal heart monitors “are potentially dangerous to the mother and baby’s health”, The RCM website says: “Expectant mothers have been warned against the use of home fetal Doppler devices over fears that they may give false reassurances to mothers about the health of their baby.”
Please help us raise awareness of the importance of Baby's movements and discourage the use of home dopplers
