New home device could let moms track Baby's heartbeat
NCT ID NCT07223996

Summary
This study tested a new device called PregnaOne that lets pregnant women monitor their baby's heart rate and their own contractions from home. About 71 women in their third trimester used the device during a single visit and compared it to an already-approved monitor. The goal was to see if the new device works just as well and is easy for women to use on their own.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- PregnaOne System (device)
- What this could lead to
- If successful, this device could offer a convenient way for pregnant women to monitor their baby's heart rate and contractions from home, potentially reducing hospital visits.
- What could go wrong
- This is a small, early-stage study focused on comparing the device to an existing one, not on health outcomes. The device may not be as accurate or easy to use in real-world settings.
