The Interpretation of Dyspnea in the Patient with Asthma
Physicians have noted dyspnea in severely ill asthmatic patients to be associated with fright or panic; in more stable patients dyspnea may reflect characteristics including lung function, personality and behavioral traits. This study evaluates the symptom of dyspnea in 32 asthmatic patients twice: first when acutely ill and again after an initial response to therapy. Spirometry was performed, ...
متن کاملFrequency of asthma as the cause of dyspnea in pregnancy.
OBJECTIVE To estimate the prevalence of asthma among pregnant women with dyspnea. METHODS Pregnant women referred for prenatal care visits who had complaints of dyspnea were included. All pregnant women were evaluated by a respiratory specialist. Spirometry was performed by a single trained physician. RESULTS Asthma was diagnosed in 38.8% of participants.
