To evaluate the effects of current supportive care measures for the adult respiratory distress syndrome (ARDS) upon the upper airway, we studied 30 survivors of ARDS. All patients were interviewed and examined and performed inspiratory and expiratory maximal flow-volume curves more than six months after the onset of ARDS. Three women had developed symptomatic upper airway obstruction due to lar...

preoperative diagnosis of an airway obstruction should alert anesthetist to a potentially life threatening situation. intubation of the trachea while the patient is awa- ke or tra~heostomy under local anesthesia is a most useful technique and safty method in induction of anesthesia where problems are anticipated during the induction or g e ne r a l anesthesia.

tracheomegaly or tracheobronchomegaly is a rare syndrome which is characterized by dramatic dilatation of the trachea and the major bronchi. this syndorme is usually associated with chronic respiratory infection and airway obstruction. in this paper, a case with tracheomegaly and bronchiectasis was scrutinized.

Clinical signs of upper airway obstruction provide valuable information regarding the degree of airway compromise and the anatomic compartment involved but are not specific to any disease process. The purpose of the diagnostic workup is to determine the extent and nature of the condition. The extent of the physical examination depends on the degree of upper airway obstruction, and complete eval...

The natural history of lung hyperinflation in patients with airway obstruction is unknown. In particular, little information exists about the extent of air trapping and its reversibility to bronchodilator therapy in those with mild airway obstruction. We completed a retrospective analysis of data from individuals with airway obstruction who attended our pulmonary function laboratory and had ple...

OBJECTIVE To assess the prevalence of distal airway obstruction and its risk factors in agricultural areas. METHODS A cross sectional study of respiratory symptoms and lung function was performed among French farmers and their spouses (1122 subjects) who came for preventive medicine examinations. They answered a respiratory questionnaire and performed pulmonary function tests on a portable sp...

OBJECTIVE To examine the feasibility of using expiratory capnography as an indicator of airway obstruction in non-intubated resuscitation room patients. METHODS Patients with potential respiratory compromise admitted to the resuscitation room were assessed for widespread expiratory wheeze. This was taken as clinical evidence of airways obstruction. Expiratory capnograms of these patients and ...

OBJECTIVES/HYPOTHESIS To evaluate the clinical value of polysomnography in patients with a tracheotomy due to chronic upper airway obstruction prior to attempting decannulation. STUDY DESIGN Retrospective chart review. METHODS Subjects with chronic upper airway obstruction were identified using a clinical database between 2000 and 2014. All subjects had a tracheotomy, were assessed by the s...

BACKGROUND The clinical manifestations of severe asthma are heterogeneous. Some individuals with severe asthma develop irreversible fixed airway obstruction, which is associated with poor outcomes. We therefore investigated the factors associated with fixed airway obstruction in Korean patients with severe asthma. METHODS Severe asthma patients from a Korean adult asthma cohort were divided i...

BACKGROUND Single lung transplantation (SLT) is now a treatment option for patients with both pulmonary fibrosis and advanced chronic airway obstruction. Lung function after transplantation might be expected to be different in these two groups of patients because of the effect of the remaining native lung, but the implications of these differences have not been fully explored. METHODS The fun...
