a full heat-and-moisture-exchanger, which is used for
partial restoration of the lost upper airway functions.
It also separates the speech valve from direct contact

coughed into the valve part of the device. It also reduces
the risk of inhalation of small particles, e.g. coming from
a defective valve.

thetic vocal and pulmonary rehabilitation after a total

tion include, but are not limited to: Radiotherapy doses
greater than 70 Gy in 7 weeks, poor overall physical
