In this study, flow field characteristics in the trachea region in a realistic human upper airway
model were firstly measured by particle image velocimetry (PIV) in the air under three …

Malignant central airway obstruction can cause severe breathing difficulty in a patient that
requires surgical intervention or stent implantation to alleviate it. A predictive model to …

The energy needed to drive airflow through the trachea normally constitutes a minor
component of the work of breathing. However, with progressive tracheal compression …

Background Obstructive upper airway pathologies are a great clinical challenge for the
airway surgeon. Protection against acute obstruction is critical, but avoidance of …

Pressure in arteries is difficult to measure non-invasively. Although computational fluid
dynamics (CFD) provides high-precision numerical solutions according to the basic physical …

Introduction High-flow nasal cannula therapy has garnered significant interest for managing
pathologies affecting infants' airways, particularly for humidifying areas inaccessible to local …

Objective: Patients with subglottic stenosis (SGS) present with varied degree of breathing
complaints. The dyspnea index (DI) is a 10-question patient-reported outcome measure …

Acquired subglottal stenosis is an unpredicted complication that can occur in some patients
who have undergone prolonged endotracheal intubation. It is a narrowing of the airway at …

Normative trachea dimensions and aerodynamic information during development was
collected to establish clinical benchmarks and showed that airway development seems to …

Abstract 3D models of airway lumens were created from CT scans of 19 patients with
laryngotracheal stenosis. Computational fluid dynamics (CFD) simulations were completed …
