Cyanosis, a blue coloration around the mouth and lips area, always relates to a low level of oxygenated blood in the body. Newborn infants normally have cyanosis between three to five minutes after birth and become pink when the oxygen saturation rises above 85% when measured by the pulse oximeter. A fast and accurate cyanosis evaluation and further treatment need to be taken as a cyanosed baby is potentially in a critical situation. Ph.D. candidate Nur Fatihah Azmi developed a cyanosis baby mannequin, that can change color, to optimize the quality of cyanosis recognition in neonatology’s training in the near future.
