HeRO monitoring in the NICU: sepsis detection and beyond

Heart rate observation (HeRO) monitoring was developed for detection of sepsis in preterm infants. In a randomised clinical trial of 3,003 very low birthweight infants, displaying the HeRO score to clinicians significantly reduced mortality. The HeRO monitor is now in use in many NICUs in the USA and was approved in 2012 for use in Europe.
