and lowering the risk of iatrogenic injuries, according to a series of tests on neonates in two level III NICUs.
“By eliminating wired connections, these platforms also facilitate therapeutic skin-to-skin contact between neonates and parents, which is known to stabilize vital signs, reduce morbidity, and promote parental bonding,” lead author Ha Uk Chung of the University of Illinois at Urbana-Champaign and coauthors wrote in Science.
In an effort to replace current wired systems that rigidly attach to fragile neonate skin, the investigators created a pair of ultrathin, noninvasive devices that can capture and transmit full vital signs with clinical-grade precision. One of the devices is mounted on the chest and captures ECGs; the other records photoplethysmograms from the base of the foot. That data plus skin temperature is wirelessly transmitted and used to measure heart rate, respiration rate, blood oxygenation, and systolic blood pressure via pulse arrival time.
The devices were tested on neonates in two level III NICUs; the infants had gestational ages ranging from 28 weeks to full term, and the results “demonstrate[d] the full range of functions,” the investigators noted. Because the devices are smaller and lighter, they interface with infant skin with forces that are “nearly an order of magnitude smaller” than adhesives used with conventional NICU measuring systems. The coauthors also noted that these cost-effective systems have potential uses beyond typical hospital settings, including “potential relevance to global health.”
No conflicts of interest were reported.
