An apparatus and method for performing warming therapy is described. In one exemplary embodiment, the apparatus includes a base for supporting a medical patient and a duct cover removably coupled to the base. The duct cover may include first and second portions which cooperate with one another to form an air flow trench between a humidifier module and a fan unit. The duct cover operates to direct humidified air from the humidifier module directly to the fan unit, so that excess moisture around the apparatus is minimized.
