Abstract:
Pediatric tracheostomy dependence is associated with a variety of sequelae. Vocalization delay is commonplace and may result in long-term communication disability. Passy-Muir speaking valves are routinely used to allow such children to vocalize. Unfortunately, not all tracheostomy dependent children can tolerate the placement of a speaking valve. Elevated transtracheal pressures are often associated with failure. We describe a method of modifying a standard Passy-Muir valve to decrease transtracheal pressures and thus improve tolerance of the valve. In our practice, the modification allows a broader range of children experience the benefit of speaking valve placement.

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,...

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...
