A substantially rigid cannula having a channel configured to sequentially house a slidably removable video camera and to provide a ventilating airway upon sealable engagement of a ventilation extension with the channel after the camera is removed. The camera is connected with a monitor to guide the placement of the cannula and its placement within the tracheal lumen. Upon engagement with the channel and a ventilating source, a breathable airway is established through the cannula.
