Abstract
According to various embodiments, a tracheal tube may include a pressure monitoring lumen configured to sample the gases in the tracheal space. The pressure monitoring lumen may be in fluid communication with a pressure transducer that provides pressure measurements. An opening of the lumen may be covered with a porous membrane that allow gas to diffuse freely in and out of the lumen, but that prevents secretions from clogging the lumen.
