Tracheobronchomalacia and excessive dynamic airway collapse are two separate forms of
dynamic central airway obstruction that may or may not coexist. These entities are …

One of the long held tenets of pediatric anesthesia has been the notion that the pediatric
airway is conical shape with the narrowest area being the cricoid region. However, recent …

Background: In some patients chronic asthma results in irreversible airflow obstruction. High
resolution computed tomography (HRCT) has been advocated for assessing the structural …

The purpose of this review is to capture the current state-of-the art of the technical aspects of
multiplanar and three-dimensional (3D) images and their thoracic applications. Planimetric …

Airway dimensions are difficult to quantify bronchoscopically because of optical distortion
and a limited ability to gauge depth. Anatomical optical coherence tomography (a OCT), a …

The ability to measure airway dimensions is important for clinicians, interventional
bronchoscopists and researchers in order to accurately quantify structural abnormalities and …

Background The flow in the human trachea is turbulent. Thus, the tracheal resistance (R)
and the pressure gradient (ΔP) required to maintain a given flow across the trachea is …

Chin lift and jaw thrust are two common maneuvers used to improve the patency of the
upper airway during general anesthesia. We investigated the effect of these maneuvers …

Purpose: Airway remodeling may be responsible for irreversible airway obstruction in
asthma, and a low post-bronchodilator FEV1/FVC ratio can be used as a noninvasive …

OBJECTIVES Severity of airway narrowing is relevant to management decision-making
processes in patients with laryngotracheal stenosis. Airway lumen is frequently assessed …
