Dyspnea is a difficulty in breathing. Symptoms of dyspnea may vary depending on the disorder that causes it: it can be accompanied by a change in acceleration of the respiratory rate known as tachypnea, or a deceleration, called bradypnea. It can affect the inhalation time, exhalation time, or both. Dyspnea is most frequently pulmonary or cardiac in origin, and may be due to asthma, airways obstruction, such as a foreign body, an infection or other lung disease, and heart problems such as a pulmonary embolism or heart failure. Dyspnea can be reduced or stopped once the cause is treated.
