Shortness of breath (SOB), also known as dyspnea (AmE) or dyspnoea (BrE), is a feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of the distinct sensations, the degree of distress involved, and its burden or impact on activities of daily living. Distinct sensations include effort/work, chest tightness, and air hunger (the feeling of not enough oxygen). The tripod position is often assumed. Dyspnea is a normal symptom of heavy exertion but becomes pathological if it occurs in unexpected situations or light exertion. In 85% of cases it is due to asthma, pneumonia, cardiac ischemia, interstitial lung disease, congestive heart failure, chronic obstructive pulmonary disease, or psychogenic causes, such as panic disorder and anxiety. The best treatment to relieve shortness of breath typically depends on the underlying cause.
