Laryngectomy: humidification
Evidence‐based approaches
As with patients who have a tracheostomy, humidification for laryngectomy patients is essential since the natural mechanisms of humidification, warming and filtration of inspired air normally provided by the upper airways are permanently bypassed (Clarke et al. [48]).
The following choices are available:
- Humidification systems: a heat and moisture exchanger (HME) consists of a laryngectomy tube or baseplate/housing that attaches to the neck and contains a filter cassette (Figure 12.54b and c). This system is highly recommended as it provides maximum protection and humidification of the airway. There are a range of types of filter and baseplate.
- Stoma covers: these filter and humidify inhaled air and are available in a variety of sizes and attachments (Figure 12.54d).
