Warning over home baby monitors

Two commercially available monitors miss low oxygen saturations

Two home baby monitors fall far below hospital equipment when it comes to accurately alarming when an infant's vital signs are off-track, US researchers say.

The commercially available monitors Baby Vida and Owlet Smart Sock 2, which can be brought online in Australia, are not approved by the US Food and Drug Administration.

Both promise to sound an alarm via parents' cell phones if their baby's heart rate or blood oxygen levels move into danger zones, according to the online study published in JAMA.

To get a sense of how well the current generation of home vital-signs monitors worked, the researchers hooked 30 infants up to a hospital monitor on one foot and one of the consumer monitors on the other.

The Baby Vida missed 102 occasions in which the baby's oxygen saturation was too low and often falsely displayed low pulse rates.
