What is an HME?

An HME is a Heat and Moisture Exchanger, which in short helps the Laryngetomee to restore some of their normal respiratory functions.

Before a Laryngectomy, your nose and throat would filter the air you breathe before it reaches your windpipe and lungs. When you have a Laryngectomy and the air you breathe is redirected through your stoma, it bypasses the nose and throat and therefore air isn’t filtered and humidified as it normally would be.

The dry and cool air you breathe is filtered through the HME and moistened and warmed to protect your trachea, as it would be before a Laryngectomy is performed.
