Performance characteristics of two double-walled infant incubators.

Two double-walled incubators, the Air Shields C-100 and the Ohio IC, were evaluated for performance characteristics. The Ohio incubator heated more rapidly from room temperature to 36 degrees C, but overshot the preset air temperature and produced greater fluctuation in air temperature due to the operation of the servocontrol system at equilibrium. Neither incubator produced excessive air currents, sound levels, or carbon dioxide accumulation.

A double-walled incubator alters the partition of body heat loss of premature infants.

Partitional calorimetry was used to assess the influence of a double-walled incubator (Air-Shields C-86 Isolette) on the body heat loss of eight premature newborn infants (birth weights 1.44-1.89 kg, ages 6-19 days). Each infant was studied in the same incubator with and without the inner wall. Incubator heater output was regulated by servocontrol to maintain the abdominal skin temperature at 36.5 degrees C. Operative environmental temperature was the same (mean 33.0 degrees C) in both incubators. There were no differences in body temperatures, oxygen consumption, carbon dioxide production, respiratory quotient, or evaporative water and heat losses. The double-walled incubator reduced radiant heat loss but increased convective heat loss, so that the total rate of body heat loss was unchanged.
