Summary

The measurement of how much oxygen a baby consumes provides important information about the health of the baby, and of how much energy they are consuming. Currently, there is no device which measures either oxygen consumption, or another variable that depends on oxygen consumption - resting energy expenditure - in neonates or infants. Our group has developed a new device which can attach to any ventilator and measures these two variables with accuracy in the preclinical setting, including in rodents as small as severely preterm infants. The purpose of this study is to compare measurements of oxygen consumption and energy expenditure in neonates using this device and comparing it with a gold standard which is rarely used, a Douglas bag method in which expired gas is collected and later analyzed.
