1. Dyspnea: exertional dyspnea occurs in the early stage, and when it progresses to a certain degree, the patient cannot lie down or sit up to breathe, and sometimes paroxysmal dyspnea occurs at night, accompanied by profuse sweating, and so on.
2. Coughing and sputum: coughing and sputum often occur at night, early white frothy sputum, when serious, pink frothy sputum or bloody sputum; occasionally hemoptysis can occur.
3. Fatigue and tiredness: Due to blood stagnation in the pulmonary circulation, cardiac output is insufficient and tissue perfusion is insufficient, resulting in fatigue and tiredness.
Pulmonary edema can also cause cyanosis, painful expression and other hypoxia manifestations. If the above symptoms occur, please go to the hospital in time to find out the cause of the disease and carry out standardized treatment as soon as possible.
