Abstract
A method of controlling a ventilation bed having an airflow control apparatus to selectively deliver a required amount of air supplied from an air conditioning system into a region of a pad divided into a plurality of regions, a switch to select at least a portion among the regions of the pad, an airflow control portion to be rotatable and that regulates a total amount of the air discharged therefrom, includes detecting, by pressure detecting sensors, whether a pressure is applied on the regions of the pad or not, when an automatic mode is selected by a switch, determining a relative pressure ratio value of the regions of the pad, by a control portion, when the pressure is applied on the pad, and regulating the amount of the air delivered into the regions by controlling operation of the airflow control portion in accordance with the pressure ratio of the regions.
