A fenestrated trach tube is similar to other trach tubes but has one added feature. It has one or more holes in the outer cannula. The holes allow air to pass from your lungs up through your vocal cords and out through your mouth and nose. It lets you breathe normally, speak using your vocal cords and cough out secretions (mucous) through your mouth.
Leading brands like Shiley, Portex, Provox and more bring you varying types of fenestarted tracheostomy tubes at shopbnebulizer.com
