Abstract :
An apparatus to calibrate the system for measuring neonatal O2 consumption and CO2 production has been developed. This system is based on the alcohol combustion principle. For an in vitro test of an indirect calorimetric system, alcohol combustion is very often used, due to its simplicity and stability. In this paper, the design can burn alcohol continuously at a rate of 0.006 ml/min and consumes O2 only 7.86 ml/min, which is in the range of neonatal breath, especially for premature infants. An alcohol combustion test which operates precisely under a desirable low combustion rate for imitating the breath of a small sized infant, and is suitable for canopy open circuit systems, is developed. It will be helpful in the study of neonatal energy consumption
