BACKGROUND AND AIM COPD is a progressive and irreversible disease, thus assessing the impact of the disease on health-related quality of life (HRQOL) is important in the management of COPD. The aim of this study was to examine the relationship between HRQOL, lung function and dyspnea rating in patients with stable COPD. METHODS One hundred COPD patients (mean age = 64.76 +/- 11.43 years) were...

BACKGROUND The objective of this study was to assess the validity and reliability of the Korean version of chronic obstructive pulmonary disease assessment test (CAT) and Dyspnea-12 Questionnaire for patients with bronchiectasis or tuberculous destroyed lung. METHODS For 62 bronchiectasis patients and 37 tuberculous destroyed lung patients, 3 questionnaires including St. George's Respiratory ...

Dyspnea is a common and disabling symptom of respiratory and heart diseases, which is growing in incidence. During hospital admission, breathlessness is under-diagnosed and under-treated, although there are treatments available for controlling the symptom. We have developed a tailored implementation strategy directed to medical staff to promote the application of these pharmacological and non-p...

CONTEXT The symptomatic benefits of oxygen in patients with cancer who have nonhypoxic dyspnea are not well defined. OBJECTIVE To determine whether or not oxygen is more effective than air in decreasing dyspnea and fatigue and increasing distance walked during a 6-minute walk test. PATIENTS AND METHODS Patients with advanced cancer who had no severe hypoxemia (i.e., had an O2 saturation lev...

OBJECTIVE To highlight the concept that stress can be associated with dyspnea in children. METHODS A chart review identified 22 patients (age range, 9-17 years) referred to a pediatric pulmonologist, who were offered instruction in self-hypnosis for treatment of dyspnea that persisted despite medical therapy. Patients were offered the opportunity to use hypnosis to gain insight into the cause...

The respiratory-related evoked potential (RREP) is an established technique to study the neural processing of respiratory sensations. We examined test-retest reliability RREP during unloaded baseline condition (no dyspnea) and inspiratory resistive loaded breathing (dyspnea) over a one-week period. RREPs were by short occlusions (150 ms) while EEG was continuously measured. mean amplitudes comp...

BACKGROUND Dyspnea while performing the activities of daily living has been suggested to be a better measurement than peak dyspnea during exercise. Furthermore, the inspiratory capacity (IC) has been shown to be more closely related to exercise tolerance and dyspnea than the FEV1, because dynamic hyperinflation is the main cause of shortness of breath in patients with COPD. However, breathlessn...

Chronic Fatigue Syndrome (CFS) subjects have many systemic complaints including shortness of breath. Dyspnea was compared in two CFS and control cohorts to characterize pathophysiology. Cohort 1 of 257 CFS and 456 control subjects were compared using the Medical Research Council chronic Dyspnea Scale (MRC Score; range 0-5). Cohort 2 of 106 CFS and 90 controls answered a Dyspnea Severity Score (...
