When there is difficulty in breathing, it can cause dizziness, because when there is difficulty in breathing, there is usually hypoxia or carbon dioxide retention, like hypoxia, which can directly cause insufficient oxygen supply to the head. If carbon dioxide is retained, it will become carbonic acid in the blood because carbon dioxide cannot be expelled, which will cause acidosis, and acidosis also has an effect on the central nervous system, which can cause delirium and coma, and dizziness is still considered light. So respiratory distress can cause dizziness in any way, and it is useless to curb dizziness in this case. We must actively treat the cause of respiratory distress and correct the lack of oxygen and carbon dioxide retention in order to really treat dizziness.
