What is dyspnea

summary

Dyspnea, as the name suggests, is a symptom of dyspnea. Dyspnea can usually be caused by many factors. It brings inconvenience and trouble to patients' daily life. Now let's talk about the disease of dyspnea.

What is dyspnea

First, the most common cause is pulmonary diseases. Diseases causing tracheal stenosis, such as laryngeal edema, laryngeal spasm, tracheal tumor, tracheal foreign body, bronchial asthma and chronic obstructive pulmonary disease, can show dyspnea due to the increase of airway resistance, and "three concave sign" can appear when the dyspnea is serious.

Second: cardiogenic dyspnea is also more common. When the cardiac function is decreased, the cardiac pumping function is reduced, and the fluid accumulates in the lung to produce pulmonary edema, which can appear or aggravate during activity. Cardiogenic asthma is caused by excessive accumulation of fluid in the lung to produce pulmonary edema, which leads to narrow airway and dyspnea.

Third: Central dyspnea occurs when the central respiratory function of the brain decreases. It is commonly caused by intracranial pressure rise caused by various reasons, central function inhibition caused by drugs, or sudden brain damage, such as cerebral hemorrhage, brain trauma, etc. it can appear tachypnea, slow breathing or even apnea, which is called periodic or Chen Shi's breathing.
