Airway Protection After Total Laryngectomy

A heat and moisture exchanger (HME) partly restores the important respiratory functions of the nose. This simple filter captures heat and moisture from the expired air. During inhalation, the air picks up some of the deposited heat and moisture from the HME, thereby raising the temperature and water content of the air entering the tracheobroncheal tree. Figure 1.6 is a schematic drawing of this process.
