AbstractThe subjective perception of pulmonary dyspnea varies based on behavioral and physiological responses. Acute pulmonary dyspnea is the most common symptom of diseases of the airways and the lungs and the differential diagnosis includes harmless causes, such as lack of training as well as acute life-threatening diseases, such as thromboembolism, obstruction of the upper or lower airway, pneumonia, pulmonary hemorrhage and pneumothorax. Most cases of chronic pulmonary dyspnea result from asthma, chronic obstructive pulmonary disease (COPD), pulmonary arterial hypertension, pulmonary fibrosis and pleural disorders. Listening to the patient's "language of dyspnea" may already provide indications for the diagnosis. Initial testing includes chest radiography, spirometry, complete blood count and the basic metabolic panel. Measurement of brain natriuretic peptide levels may help to exclude heart failure in COPD and D-dimer testing may help rule out pulmonary embolisms. Computed tomography of the chest is the most appropriate imaging procedure for diagnosing pulmonary embolism and interstitial lung disease. To diagnose pulmonary arterial hypertension echocardiography and right heart catheterization may be necessary.
