A device known as the Pea Pod, which resembles a miniature MRI machine, is used to measure the body composition of the infants. The Pea Pod is heated and the baby is placed inside for about three minutes. Using an air displacement method, the machine senses change in pressure and can determine the percentage of body weight that is fat and the percentage that is lean body mass. With this information, the NICU team can then personalise the baby’s nutritional supplements to help with proper weight gain. - See more at: https://healthmanagement.org/c/icu/news/neonatal-icu-new-technology-helping-babies-progress-faster#sthash.uc92LfiF.dpuf
