An infant warmer includes an infant enclosure defining an infant compartment, and a heating system pneumatically coupled with the infant compartment. The dome and lower housing create an air tight space, wherein the barometric pressure is raised by a blower, in order to pop foam bubbles and allow for optimum mixing of air into the oxygen depleted liquid, and intake and discharge openings of the lower housing are positioned beneath the liquid line, thereby preventing the escape of foam, noise and odorous gases into the local environment.
