Abstract:
An infant born at full term presented with tachypnea, tachycardia and fatigue with feedings. Blood gases revealed hypoventilation. A rigid bronchoscopy using the Karl-Storz telescopic system revealed severe tracheal stenosis. Follow-up three-dimensional computerized tomography scans of the neck and chest revealed a long segment, funnel-shaped tracheal stenosis extending up to the left bronchial orifice. The patient underwent tracheal reconstruction, but died three weeks later from postoperative complications. It is unusual for severe tracheal stenosis to present without stridor, apnea, cyanosis and wheezing. Infants with unexplained tachypnea should be worked-up for congenital deformities of the upper airways.

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...
