What the FDA Says
The FDA has cleared home fetal dopplers as Class II medical devices — meaning they have demonstrated substantial equivalence to legally marketed predicate devices in safety and effectiveness for their intended use. The FDA has also issued guidance noting that while the devices are safe when used properly, expectant parents should not use them to self-monitor for fetal distress or replace professional monitoring. The HeartBeats™ complies with FDA 510(k) clearance requirements and is labeled accordingly.What ACOG (American College of OB/GYNs) Says
ACOG’s primary concern with home fetal dopplers is not the technology itself — it is the risk of false reassurance. Specifically:- A detectable heartbeat does not confirm fetal well-being
- An inability to find the heartbeat may cause unnecessary anxiety or, conversely, a false sense of reassurance if the user finds a signal they mistake for fetal tones
- Home dopplers should not be used to assess fetal distress or respond to reduced fetal movement
The Real Risk: False Reassurance
The most significant safety concern with home fetal dopplers is not physical harm from ultrasound — it is the risk that a parent hears a heartbeat (possibly their own pulse, the placenta, or a movement artifact) and delays seeking medical attention.Responsible Use Guidelines
The HeartBeats™ is designed for responsible, occasional bonding use:- Use occasionally — not as a daily clinical monitoring device
- Do not use to assess fetal distress — contact your provider instead
- Learn what you’re hearing — know the difference between baby’s heartbeat (fast, 120–180 BPM), your pulse (slow, 60–100 BPM), and placental sounds (rushing, slower)
- Always contact your provider if you cannot find the heartbeat, if movement has reduced, or if you have any concerns
- Use with gel — dry use produces poor signal and may lead to misidentification of sounds
Physical Safety of Ultrasound
Diagnostic ultrasound at the power levels used in home fetal dopplers has been studied extensively and has not been shown to cause harm to developing fetuses when used appropriately. The output of consumer fetal dopplers is within established safety limits. The 2.5 MHz frequency used in the HeartBeats™ is the same frequency range used in clinical handheld dopplers worldwide.The Bottom Line
The SonoHealth HeartBeats™ Fetal Doppler is safe for its intended purpose: hearing your baby’s heartbeat for reassurance and bonding between prenatal appointments. It is FDA-cleared, uses standard ultrasound technology, and is labeled with appropriate safety information. It is not a substitute for prenatal care, clinical monitoring, or medical evaluation. Used responsibly, it is a meaningful bonding tool for expectant parents.Shop HeartBeats™ Fetal Doppler
