Abstract: An infant incubator and a process for regulating an environment of an incubator. The incubator includes a chamber that is formed when a hood is secured to a base. The infant rests atop a variable temperature mattress within the chamber. The base includes a water circuit, which includes a pump, a water heater, a temperature sensor, and at least one nebulizer. A mixing manifold is secured within the base, which includes the at least one nebulizer, at least one inlet fan and at least one air heater. Water heated by the water heater is nebulized into water particles via the at least one nebulizer and the nebulized water particles are combined with the heated air within the mixing manifold. The combined nebulized water particles and heated air are introduced into the chamber at a controlled rate.
