[Dysphagia due to tracheotomy]
1HNO, Phoniatrie und Pädaudiologie, München.
Fundamentals:
Dysphagia is a common appearance after tracheostomy especially in patients with neurologic diseases of the following reasons: 1. fixation of trachea and larynx to the scin leads to lack of laryngeal elevation in a forward and upward direction, 2. pressure in the upper esophagus may be increased following high cuff pressure, 3. reduction of hypopharyngeal and laryngeal sensitivity and alteration of the coughing mechanism, 4. loss of olfactorial and gustatorial stimulation of the swallowing process.
Conclusion:
Consequently noninvasive ventilation modes are recommended alternatively in patients with respiratory insufficiency.

Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Oxygen Delivering System III: Tracheostomy and T-piece
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
