The clinical term dyspnea (a.k.a. breathlessness or shortness of breath) encompasses at least three qualitatively distinct sensations that warn of threats to breathing: air hunger, effort to breathe, and chest tightness. Air hunger is a primal homeostatic warning signal of insufficient alveolar ventilation that can produce fear and anxiety and severely

Assessment of Dyspnea in Asthma: Validation of the Dyspnea-12 [PDF]
Journal of Asthma, 2011 Dyspnea is a prominent symptom in asthma. The Dyspnea-12 (D-12), an instrument that quantifies breathlessness using 12 descriptors that tap the physical and affective aspects, has shown promise for the measurement of dyspnea in cardiorespiratory disease.We report the results of a study designed to test the validity and reliability of the D-12 in a ...

Clinics in Chest Medicine, 1980
Dyspnea, an unpleasant sensation of difficulty in breathing, is a common accompaniment of cardiopulmonary disease. The underlying mechanisms generating this sensation are not clearly understood. There does not appear to be any one specific site or specific receptor(s) involved in this sensation; however, reflex increase in central respiratory motor ...

JAMA: The Journal of the American Medical Association, 1978
ABSTRACT To the Editor.— In a letter published recently in The Journal (239:928, 1978) E. D. Morton, MD, asks what dyspnea means and whether it refers to a subjective symptom or an objective sign. Since etymological or historical arguments showing what a word ought to mean are out of style, the answers to these questions should be sought through ...

AACN Advanced Critical Care, 2011
Patients experiencing a dyspnea exacerbation will often report feeling smothered or suffocated. This highly distressing, prevalent, multidimensional symptom is the chief complaint signifying pulmonary dysregulation. Increasing dyspnea intensity heralds the onset of respiratory failure, leading to hospitalization and/or admission to the intensive care ...

Clinics in Chest Medicine, 1987
An unpleasant sensation of difficulty in breathing is a common complaint in a variety of disease states. The psychophysical approach to the study of respiratory sensations has contributed greatly to the understanding of the mechanisms of dyspnea. Although dyspnea, in large part, is an expression of the sense of the effort of breathing, the intensity ...

Current Opinion in Pulmonary Medicine, 2006
Dyspnea--the perception of respiratory discomfort--is a primary symptom of asthma. This review examines possible ways to link mechanisms, measurement and treatment that will increase our understanding of this condition.Functional neuroimaging methods have proven to be powerful tools that serve as advanced models of sensor motor brain function.

AACN Clinical Issues: Advanced Practice in Acute and Critical Care, 1997
Acute dyspnea is a common symptom in the adult patient in the hospital and often requires rapid assessment and intervention. This sensation accompanies a variety of disorders, including an exacerbation of underlying chronic pulmonary disease, acute pulmonary disease, abnormalities in gas exchange, cardiac disease, neuromuscular dysfunction, and anxiety

Diseases of the Chest, 1963
The exact nervous mechanism of dyspnea remains uncertain, but the simplest arrangement would be one in which information concerning chest volume and the pressure developed within the chest is correlated. Alteration in the chest volume may be appreciated as a length change, perhaps in terms of the length of the muscle fibers or of the angular rotation ...
