What are the common symptoms of pulmonary embolism?

Model:Pulmonary Artery

Pulmonary embolism is a condition caused by a blood clot blocking the pulmonary artery or its branches. It is usually caused by a blood clot in the deep veins of the lower extremities (DVT) that forms and migrates to the pulmonary artery. The symptoms of pulmonary embolism can vary depending on the size, number and location of the clots, and the severity also varies. The following are some common symptoms that pulmonary embolism may present:

Respiratory symptoms:

Shortness of breath: Pulmonary embolism can lead to restricted gas exchange, causing the patient to feel short of breath.

Dyspnea: Severe pulmonary embolism may cause a feeling of shortness of breath, especially during physical activity.

Chest pain: Chest pain is a common symptom of pulmonary embolism. It is usually severe and sudden chest pain that may be aggravated by deep breathing, coughing or exercise.

Cough: Sometimes a cough occurs, and the sputum coughed up may contain blood or blood clots.

Cardiovascular symptoms:

Palpitations: Pulmonary embolism may cause palpitations, that is, a feeling of rapid or irregular heartbeats.

Low blood pressure: Severe pulmonary embolism may cause a drop in blood pressure, resulting in symptoms of low blood pressure.

Fever: In some cases, the patient may have a fever, but this is not a specific symptom of pulmonary embolism.

Altered consciousness: In extremely severe cases, pulmonary embolism may cause altered consciousness or even coma.

The pulmonary artery model extends from the femoral vein to the heart and pulmonary artery. The model includes major blood vessels such as the femoral vein, iliac vein, inferior vena cava, right atrium, right ventricle, pulmonary artery, superior vena cava, internal jugular vein, and external jugular vein. The model has 10 pulmonary artery grades for the left and right pulmonary arteries respectively, and the end of the pulmonary blood vessels has customizable pulmonary embolism, malformations and other lesions. The model is mainly used for simulation training of pulmonary embolism, pulmonary hypertension, pulmonary artery malformations, and venous system interventional pathway training; it can also be used for the development, testing and verification of pulmonary artery interventional treatment devices; various training and market demonstrations for pulmonary artery treatment.
