密闭孵育器中辐射温度评价

In closed incubators, radiative heat loss (R) which is assessed from the mean radiant temperature  accounts for 40–60% of the neonate’s total heat loss. In the absence of a benchmark method to calculate —often considered to be the same as the air incubator temperature—errors could have a considerable impact on the thermal management of neonates. We compared  using two conventional methods (measurement with a black-globe thermometer and a radiative “view factor” approach) and two methods based on nude thermal manikins (a simple, schematic design from Wheldon and a multisegment, anthropometric device developed in our laboratory). By taking the  estimations for each method, we c
