during insertion. Adjust the cuff pressure to the individual venti-
lation therapy and check at regular intervals. Typically, the pres-
sure should be between 20 cmH
(≈ 22 mmHg). Attaching a hand-held manometer causes a fall in
cuff pressure. This effect is more marked with small sizes.
8.4 Removing the Tube (see chapter 8.2)
Prepare to remove the tube as follows:
• Bend the patient's head slightly backwards and
• completely unblock the cuff of cuffed tubes (see chapter 8.5).
8.5 Unblocking the Cuff
Before unblocking, ensure that as little secretion as possible can
enter the bronchi.
While the cuff is being unblocked, suction secretions with a suc-
tion catheter passed through the tube. If tubes with subglottic
suction have been used, also aspirate the subglottic area before
unblocking the cuff, see chapter 9.5.
To unblock the cuff, connect a syringe to the pilot balloon (2a).
Completely remove all air/condensate if applicable. (See chapter
5. "General Precautions").
If it is not possible to unblock the cuff, apply the following measures:
• Remove the inner cannula. Make sure that the inflation line
(2a) is not kinked and unblock the cuff again.
• If it is still not possible to unblock the cuff: carefully cut
through the inflation line between the 15 mm connector (3) and
the neck flange (5).
9. Handling
9.1 Changing the Inner Cannulas
If viscous secretion collects in the inner cannula and cannot be
suctioned, thus impeding the airflow, replace the inner cannula
with a new or cleaned inner cannula.
To remove the inner cannula, turn the 15 mm connector of the
inner cannula anticlockwise (C).
Once a new inner cannula has been inserted into the outer can-
nula, turn the 15 mm connector of the inner cannula clockwise
until it locks into place, i.e. until the blue arrows and/or embossed
markings are aligned with each other (C).
Inner cannulas with grooved low profile connectors function in
the same way.
