MRT is a diagnostic imaging technique in which inner organs, tissues and joints are depicted
with the help of magnetic fields and radio waves. Metallic objects can be drawn into the mag-
netic field and can induce changes by their acceleration. Although the metal spring is extremely
EN
small and lightweight, interactions that could give rise to health impairments or to malfunction or
damage of the technical equipment used or of the tracheostomy tube itself nevertheless cannot
be ruled out in this context. If wearing a tracheostomy tube is indicated for keeping the tracheo-
stoma open, we recommend use of a metal-free tracheostomy tube instead of the tracheostomy
tube with cuff while an MRT is being performed.
CAUTION!
Do not use a tracheostomy tube with cuff while a nuclear magnetic imaging/MRI exami-
nation is being performed!
1. Neck flange
A particular feature of the Fahl tracheostomy tube is the specially shaped neck flange,
®
which is designed to fit the anatomy of the neck.
The neck flange of the tracheostomy tubes has two side eyelets for inserting a tube holder.
All Fahl tracheostomy tubes with fastening eyelets include a disposable tube holder. The
®
tube holder secures the tracheostomy tube to the neck.
The size specifications are printed on the neck flange.
The insertion aid (obturator) included in delivery facilitates insertion of the tracheostomy
tube.
Please follow the instructions provided with the tube holder carefully when attaching and
removing it from your tracheostomy tube.
Ensure that the Fahl tracheostomy tube is placed in the tracheostoma without tension and
®
the position is not changed when fastening the tube holder.
2. Connectors and adapters
Connectors and adapters are used to connect compatible tube accessories.
The options available to a patient depend on the clinical condition, such as status post
laryngectomy or tracheostomy.
The inner cannula is fixed in place by means of bayonet locks, which are located on the
connector, the speaking valve and the cough cap respectively. The connector in this case
is the universal attachment (15 mm connector), with the aid of which so-called artificial
noses or heat and moisture exchangers (HMEs, filters for exchanging heat and moisture)
can be attached.
A 15 mm standard connector enables secure connection to required accessories.
3. Cannula tube
The cannula tube borders directly on the neck flange and directs the airflow into the trachea.
The swivel connector serves to securely attach inner cannulas and compatible accesso-
ries: the inner cannulas/accessories are fixed in place with only a light rotating movement
in clockwise direction (in inserted condition as viewed when facing the patient), and thus
without having to exert much tension on the tracheostomy tube.
3.1 Cuff
In the product versions with cuff, the very thin-walled, high-volume cuff adapts well to the
trachea and ensures reliable sealing if inflated correctly. The cuff can be inflated like a bal-
loon. The small pilot balloon on the inflation tube indicates whether the tracheostomy tube is
in sealed (inflated) or non-sealed condition.
The cuff itself is inflated via a tube with one-way valve and pilot balloon.
3.1.1 Leakproofness test of the cannula and the low-pressure cuff (if present)
The cannula and the cuff must be tested for leakages directly before and after every inser-
tion and thereafter at regular intervals. For this purpose, fill the cuff with 15 to 22 mmHg
O) and observe whether a spontaneous pressure
(1 mmHg corresponds to 1.35951 cmH
2
drop occurs. There should be no substantial drop in pressure in the cuff during the observa-
tion period. This leakproofness test must also be performed prior to every renewed insertion
(e.g. after cleaning the tracheostomy tube) (see picture 7c).
