Prior to the operation, breathing primarily occurs through the nasal airways. In the upper airways, the inhaled air is warmed up or cooled down, to prepare the optimal temperature before the air reaches the lungs. After a total laryngectomy, the upper airways are bypassed and breathing in and out occurs through the tracheostoma in the neck which means that the inhaled air flows directly into the lungs. These anatomical changes lead, among others, to changes in voice production, breathing, and olfaction. The nasal functions of regulating the temperature, humidifying, and filtering of the inhaled air are lost. The lack of these functions impairs the lower airways and the activity of the cilia, which leads to pulmonary problems such as tracheobronchial mucus, excessive sputum production, crusting, which can also cause fatigue and shortness of breath. To at least partially reduce these restrictions and compensate the nasal functions, an HME cassette can be attached over the tracheostoma to provide a means for conditioning, humidifying and to a certain extent filtering the inhaled air. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heat and moisture exchanger after laryngectomy」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
