Abstract
The present disclosure describes systems and methods that utilize a tracheal tube with a shaped evacuation port. An evacuation port coupled to a suction lumen may be shaped to reduce air channel formation within the suction lumen, which in turn may improve the suctioning force and efficiency. The shaped evacuation ports may be generally oval or may be shaped to minimize a height dimension while maintaining a suitable cross-sectional area. In particular embodiments, the shaped evacuation ports may have cross-sectional areas that correspond to a cross-sectional area of the suction lumen.
