STUDY OBJECTIVE To determine whether exercise training with coaching is more effective than exercise training alone in reducing dyspnea and the anxiety and distress associated with it and improving exercise performance, self-efficacy for walking, and dyspnea with activities of daily living. DESIGN Randomized clinical trial of 51 dyspnea-limited patients with COPD assigned to monitored (n = 27...

Context Dyspnea is a subjective, multidimensional experience of breathing discomfort, commonly seen in patients with advanced cancer. To find the impact of dyspnea on the quality of life in this population, it is important to understand the prevalence and factors influencing dyspnea. Aims This study aimed to determine the prevalence, intensity, and factors influencing dyspnea in advanced canc...

We evaluated dyspnea perception in cystic fibrosis patients compared with normal subjects, during an inspiratory resistive loading test and 6-min walk test. We also evaluated the correlation between dyspnea scores induced by resistive loads and by the 6-min walk test. In this prospective, cross-sectional study, 31 patients with cystic fibrosis (≥15 years of age) and 31 age-, gender-, and ethnic...

Our understanding of the nature and mechanisms of dyspnea has greatly evolved over the last two centuries. Although the relationship was never form ally specified, discomfort was always assumed to accompany respiratory muscle activity. Hypotheses and theories of dyspnea thus became synonymous with the factors controlling the extremes of respiratory muscle activity, with expiratory muscle activi...

Dermatomyositis is an inflammatory muscle disease characterized by weakness of the skeletal muscles, in particular, the proximal muscles of the arms and thighs.1 If untreated, it is associated with progressive deterioration, and the severity ranges from mild to severe and can include paralysis. The onset is slow, over months in the majority of patients, but some people have rapid onset and prog...

Dyspnea is a frequent focus of palliative care, which nurses can better address using the skills of comprehensive assessment and an updated knowledge base about appropriate medical, pharmaceutical, and nonpharmaceutical interventions. A solid clinical foundation about dyspnea allows clinicians to establish an effective plan of care. This column features two clinical case studies, which review c...

PURPOSE Dyspnea is one of the most distressing symptoms experienced by terminally ill cancer patients. This study aimed to evaluate the role of interventions for the palliation of dyspnea. METHODS We conducted a systematic review of randomized controlled trials assessing all pharmacologic and nonpharmacologic interventions for dyspnea palliation in cancer patients, and searched the Cochrane L...

Chronic dyspnea is shortness of breath that lasts more than one month. The perception of dyspnea varies based on behavioral and physiologic responses. Dyspnea that is greater than expected with the degree of exertion is a symptom of disease. Most cases of dyspnea result from asthma, heart failure and myocardial ischemia, chronic obstructive pulmonary disease, interstitial lung disease, pneumoni...

BACKGROUND There is no gold standard for the differential diagnosis of acute dyspnea despite the usefulness of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and lung ultrasound. No study has evaluated the contribution of bioelectrical impedance vector analysis (BIVA) in discriminating between cardiac and noncardiac dyspnea. We sought to determine whether a relationship exists between ul...
