Single-Lumen Tube
The single-lumen tube is similar to the double-lumen tube except that there is no
inner cannula. More intensive nursing care is required with this tube because there
is no inner cannula to ensure a patent lumen.
Fenestrated Tube

The fenestrated tube has a precut opening (fenestration) in the upper posterior wall
of the outer cannula. The tube is used to wean the client from a tracheostomy by
ensuring that the client can tolerate breathing through her or his natural airway
before the entire tube is removed. This tube allows the client to speak.

Cuffed Fenestrated Tube
The cuffed fenestrated tube facilitates mechanical ventilation and speech and often
is used for clients with spinal cord paralysis or neuromuscular disease who do not
require ventilation at all times. When not on the ventilator, the client can have the
cuff deflated and the tube capped (see Fig. 69-11 for cuffed fenestrated tube with red
cap) for speech. A cuffed fenestrated tube is never used in weaning from a
tracheostomy, because the cuff, even fully deflated, may partially obstruct the
airway.
