The pathophysiology of emphysema is best explained on the basis of decreased pulmonary elastic recoil. At any pleural pressure, the lung volume is higher than normal. Additionally, the altered relation between pleural and alveolar pressure facilitates expiratory dynamic compression of airways.

Requirement for macrophage elastase for cigarette smoke-induced emphysema in mice.
Science, 1997To determine which proteinases are responsible for the lung destruction characteristic of pulmonary emphysema, macrophage elastase-deficient (MME-/-) mice were subjected to cigarette smoke.

An 87 year-old woman with a history of hypertension, type 2 diabetes and post-menopausal osteoporosis presented with a 5-day history of low-grade intermittent fever, epigastric pain and shortness of breath. At admission, patient was normotensive but tachycardic (HR 106 beats/min) and tachypneic (RR 26 breaths/min), and oxygen saturation was 96% while ...

Emphysema: looking beyond alpha-1 antitrypsin deficiency
Expert Review of Respiratory Medicine, 2019Introduction: Distinct pathologies can cause chronic obstructive pulmonary disease (COPD). Emphysema is a COPD-phenotype characterized by destruction of lung parenchyma.

Marked erythrocytosis is frequently seen in hypoxia due to high altitudes and cyanotic congenital heart disease (Hurtado, Merino and Delgado, 1945) but is relatively uncommon in association with chronic respiratory failure (Baldwin, Cournand and Richards, 1949). This discrepancy has exercised a number of writers.

ter to its stimulating effects until, eventually, the center no longer responds to the presence of carbon dioxide. Thus, in chronic emphysema, the respiratory center-rather than responding to carbon dioxide concentrations-is stimulated by the chemoreceptors which respond to low oxygen tensions of the blood.

The induction of pulmonary emphysema with human leukocyte elastase.
American Review of Respiratory Disease, 2015Purified human leukocyte elastase was injected into the tracheas of 46 hamsters. Thirteen animals died spontaneously within 1 week, with extensive lung hemorrhage.

Combined pulmonary fibrosis and emphysema (CPFE) is characterized by preserved lung volume and slower lung function decline. However, it is unclear at what extent emphysema begins to impact respiratory physiology and prognostic characteristics in ...

Summary Criteria for the x-ray diagnosis of gross widespread emphysema with air trapping are put forward, and the variations of x-ray appearances which fulfil these criteria are described. The reliability and prognostic value of the x-ray findings are discussed.

Bronchitis proper is a distinct entity from emphysema. Causal relationship between them is exceptional rather than usual. Severe bronchitis and diffuse pulmonary emphysema are to a large extent incompatible. Simple chronic bronchitis is a common trivial disease of the central tracheobronchial tree.
