When changing the inner cannula, always ensure that the infla-
tion line (2a) of the cuff is not positioned between the inner and
outer cannulas, as it may get trapped and damaged.
9.2 Fenestrated Tracheostomy Tubes
Unfenestrated inner cannulas have white 15 mm connectors and
are used, for example, during ventilation.
To allow the patient to speak, insert a fenestrated inner cannula
(blue 15 mm connector or blue grooved low profile connector)
in the fenestrated outer cannula. Once the cuff has been un-
blocked, a speaking valve can be placed on the 15 mm con-
nector of this inner cannula. Follow the instructions for use of the
respective speaking valve.
The inner cannula REF 401 (not supplied) has an integrated
speaking valve. The valve allows air to enter the trachea through
the tube on inspiration; on expiration, the valve closes and the
air flows alongside the tube, as well as through the fenestration,
through the larynx into the upper respiratory tract, which allows
vocalisation.
If there is an urge to cough or possible breathing difficulties, the
REF 401 valve leaflets can be folded back and the patient can
breathe unimpeded.
CAUTION: Speaking valves must only be used in patients who
are awake and can breathe spontaneously. When a speaking
valve is introduced, the patient must be instructed by trained per-
sonnel and carefully monitored while becoming accustomed to it;
make sure that the patient can breathe sufficiently.
Unblock the cuff before using a speaking valve. Do not use a
speaking valve during sleep.
CAUTION: Patients with laryngeal stenosis, vocal cord paralysis,
severe tracheal stenosis, respiratory tract obstructions, respira-
tory tract infections or copious mucous secretions must not use
a speaking valve.
9.3 Occlusion Cap of the Fenestrated Tube for Weaning
The fenestrated inner cannula can be closed by attaching the
enclosed occlusion cap (10) to the 15 mm connector.
CAUTION: When preparing the tube, ensure that the patient's up-
per respiratory tract is unobstructed. The upper respiratory tract
can be cleared by coughing out or suctioning the secretions. The
