Symptoms and signs of pulmonary embolism

The symptoms and signs of pulmonary embolism include dyspnea, chest pain, cough, syncope, etc.

1. Dyspnea After

pulmonary embolism, insufficient blood flow in the lungs will lead to redistribution of blood in the lungs, resulting in imbalance of ventilation and blood flow, resulting in symptoms of dyspnea.

2. Chest pain

Due to insufficient blood flow in the lungs, it may lead to ischemia, hypoxia, necrosis of local lung tissues, resulting in symptoms of chest pain.

3. Cough

Because pulmonary embolism will affect lung ventilation, leading to poor breathing, cough may occur.

4. Syncope

Pulmonary embolism will lead to oxygen synthesis disorders in the body, which is easy to induce hypoxemia, resulting in cerebral hypoxia, and eventually syncope.
