Long-term Intratracheal Intubation in Infants with Upper Airway Stenosis.

Upper airway radiographs in infants with upper airway insufficiency

Upper airway measurements in nine infants considered to be at risk of upper airway insufficiency, six of whom presented after an apnoeic episode, were compared with measurements taken in two age groups of healthy infants. Paired, inspiratory and expiratory, lateral upper airway radiographs were obtained while the infants were awake and breathing quietly. The radiographs of all nine infants demo...

Quantitative assessment of the upper airway in infants and children with subglottic stenosis.

OBJECTIVES/HYPOTHESIS Determine whether quantitative geometric measures and a computational fluid dynamic (CFD) model derived from medical imaging of children with subglottic stenosis (SGS) can be effective diagnostic and treatment planning tools. STUDY DESIGN Retrospective chart and imaging review in a tertiary care hospital. METHODS Computed tomography scans (n = 17) of children with SGS ...

Detecting upper airway obstruction in patients with tracheal stenosis.

We propose a forced oscillation test modality for detecting upper airway obstruction (UAO) as an alternative to spirometric UAO indices in patients with tracheal stenosis. From oscillometry performed at different breathing flow rates, airway resistance at 5 Hz was determined at 0.5 l/s (R), and flow dependence of resistance was computed as the regression slope of resistance vs. flow up to 1 l/s...
