Mathematical model of premature baby thermoregulation and infant incubator dynamics

Abstract:

A thermodynamic mathematical model of premature infants placed in an infant incubator was developed to improve the control algorithm of the incubator. The validity of the baby model was tested in 5 healthy premature newborns. The difference between experimental data from direct and indirect calorimetry and the model results averaged 0.1±0.1, 0.2±0.1 and 0.2±0.2 (mean = SE) °C for the rectum, trunk and head temperatures, respectively. The incubator model showed steady state error less than ±0.1 C for air and internal wall temperatures in the air servocontrol mode. Results indicated that the model is a good tool for designing improved control algorithms of incubators.
