Capnogram Shape in Obstructive Lung Disease
Anesthesia & Analgesia, 2005Small, preliminary studies have suggested that capnograms of obstructive lung disease (OD) exhibit a characteristic shape and that this shape may be correlated to changes in forced expiratory volume in 1 s (FEV(1)). We evaluated the association between capnograms and spirometry from subjects with OD with normal and restrictive lung disease (RD ...

The major forms of obstructive lung disease are bronchial asthma and chronic obstructive pulmonary disease (COPD). Asthma is characterized by a predominantly functional bronchial obstruction that is almost entirely reversible, at least at early stages; COPD exposes structural changes and deficits of the respiratory tract, including the lung tissue ...

Bronchial Collapse in Obstructive Lung Disease
Chest, 1981A 57-year-old man who died suddenly with severe bilateral mainstem bronchial collapse is described, and an alteration of the elastic tissue in the membranous portion of the bronchi is identified. The morphologic abnormalities, physiologic dynamics, and potential clinical consequences of such an alteration are discussed.

Mechanical ventilation is often used in the setting of acute exacerbations of obstructive lung diseases like asthma and chronic obstructive pulmonary disease (COPD). These disorders are characterized by increased airway resistance secondary to bronchospasm and airway inflammation, collapse, and remodeling, often leading to inefficient exhalation and ...

Pulmonary Hemodynamics in Obstructive Lung Disease
Diseases of the Chest, 1968SUMMARY Various aspects of pulmonary hemodynamics were studied in 34 emphysema patients: (a) when the cardiac output was interpreted on the basis of each patient's age, the majority (85 per cent) showed either normal or high output, while the remainder (15 per cent) had a definitely low output.

Corticosteroids and obstructive lung disease
Practice Nursing, 2001In the first of two articles, Anne Baird examines the issues surrounding the use of inhaled therapy for COPD and considers the experience of Mrs White.The use of long-term oxygen therapy will be discussed in the forthcoming article.

Protein Misfolding and Obstructive Lung Disease
Proceedings of the American Thoracic Society, 2010The endoplasmic reticulum has evolved a number of mechanisms to manage the accumulation of incorrectly folded proteins. This results in loss of function of these proteins, but occasionally, in conditions such as α-1 antitrpysin (A1AT) deficiency, the misfolded protein can acquire a toxic gain of function promoting exaggerated ER stress responses and ...

Ventilatory Strategies in Obstructive Lung Disease
Seminars in Respiratory and Critical Care Medicine, 2014Chronic obstructive pulmonary disease (COPD) is characterized by expiratory flow limitation (EFL) due to progressive airflow obstruction. The various mechanisms that cause EFL are central to understanding the physiopathology of COPD. At the end of expiration, dynamic inflation may occur due to incomplete emptying the lungs.

Airway obstruction in interstitial lung disease
Current Opinion in Pulmonary Medicine, 1997There is no question that most interstitial lung diseases result in structural alteration of the small airways as well as the alveoli. These structural changes of the airways produce airflow abnormalities that, depending on their extent and severity, are reflected in a variety of tests of pulmonary function.

Chronic Obstructive Lung Disease
1990The term “chronic obstructive lung disease” embraces a large number of pathological conditions with the common feature of increased impedance to the air flow out of the lungs, resulting in dyspnea. The clinical, radiological, and pathophysiological features of these various (diffuse or localized) diseases are, most of the time, associated and ...
