Diagnosis Neonatal infants Monitoring the level of carbon dioxide in neonatal infants to ensure that the level is not too high (hypercarbia) or too low is important for improving outcomes for neonates in intensive care. Carbon dioxide can be monitored by taking a blood sample (arterial blood gas), through the breath (exhalation), and it can be measured continuously through the skin by using a minimally invasive transcutaneous device. The most effective and safest approach for measuring carbon dioxide in newborn infants is not clear.
