A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes flange attaches to the chest of the patient to secure the device in position. The pneumostoma management device also includes a tube which enters the pneumostoma to allow gases to escape the lung. The length of the tube is selected to match the dimensions of the pneumostoma of a patient. In order to manufacture devices having different tube lengths, the tube is formed at a longer length than required, cut to size and tipped. The tube may be formed by molding or extrusion.
