If unexplained shortness of breath, pleuritic chest pain, tachycardia, and decreased oxygen saturation occur, one should be highly vigilant about pulmonary embolism. Generally, pulmonary embolism has no direct relationship with pneumonia. High-risk factors for pulmonary embolism include obesity, prolonged immobilization, stroke, congestive heart failure, malignant tumor, inflammatory bowel disease, lower limb fracture, anesthesia time exceeding 30 minutes, and acquired or genetic hypercoagulable state. It usually manifests as difficulty breathing, rapid breathing, and pleuritic chest pain.

What are the symptoms when pulmonary embolism becomes severe?

Pulmonary embolism can vary in severity, with serious cases primarily causing unstable vital signs. The disease primarily arises from venous thrombi in the venous system, which travel with the venous blood back to the right heart, and then with the blood flow from the right heart back to the aorta. If the thrombus is relatively large, it can easily become lodged in the pulmonary artery, forming a pulmonary embolism. The symptoms of pulmonary embolism can range from mild to severe. Based on the patient's symptoms and vital signs, pulmonary embolism is categorized into low risk, intermediate risk, and high risk. Low and intermediate risk typically indicate that the patient's vital signs are relatively stable, with normal blood pressure, heart rate, and pulse oximetry saturation. In severe cases, patients may exhibit noticeable symptoms such as coughing up blood, difficulty breathing, low blood pressure, shock, and oliguria. These represent the more severe cases of pulmonary embolism.

What are the symptoms of a pulmonary embolism warning sign?

Pulmonary embolism is also very common in clinical settings, mainly seen in patients who have been bedridden for a long time, undergone various major surgeries, suffered from long bone fractures, pregnancy, etc. In the early stages of pulmonary embolism, patients generally experience varying degrees of chest pain, hemoptysis, and difficulty breathing, among others. If pulmonary embolism is suspected and the patient's condition permits, a pulmonary artery CTA scan should be immediately carried out to further confirm the diagnosis of pulmonary embolism. If the pulmonary embolism has already caused circulatory disturbances, thrombolytic therapy should then be considered.

Pulmonary embolism should be treated in the department of respiratory medicine or cardiology.

Pulmonary embolism is a pathological process in which a blood clot in the vessels detaches, affecting the pulmonary artery and its branches. After the occurrence of a pulmonary embolism, patients generally visit the respiratory medicine department. Clinically, a pulmonary artery CTA can be performed to further confirm the diagnosis. The treatment methods in clinical practice are mainly as follows: If the patient experiences circulatory disturbances, emergency thrombolytic therapy may be considered; if the patient's circulation is stable, treatment with low molecular weight heparin and warfarin anticoagulation can be considered. Of course, it is important to monitor the patient's respiration and blood pressure.

What should I do if I have pulmonary embolism and asthma?

Pulmonary embolism is a very common type of disease clinically, and its triggering factors are numerous and complex. For such patients, the main triggering factors are usually the detachment of thrombi from the pelvic deep veins and the lower limb deep veins, leading to pulmonary artery embolism. Therefore, the clinical symptoms that appear in these patients are mainly difficulty breathing, chest tightness, chest pain, and some patients may experience coughing, coughing up blood, shortness of breath, and even wheezing. Thus, for such patients, it is first necessary to clarify the cause of the disease, and then provide the patient with oxygen, thrombolysis, anticoagulation, and other symptomatic treatments. Usually, after effective symptomatic treatment, when the embolism location is effectively controlled, the symptoms of wheezing and air blockage that the patient experiences will also be significantly improved.

The most common symptoms of pulmonary embolism.

Pulmonary embolism is also relatively common in clinical practice, primarily caused by an embolus blocking the pulmonary artery system, leading to a group of clinical syndromes. The clinical manifestations of pulmonary embolism mainly include the following points: The first is that patients may experience unexplained difficulty breathing and shortness of breath, especially after activity. The second is that patients experience significant chest pain. The third may be accompanied by hemoptysis, but usually, the amount of blood expectorated is not large. The fourth is that patients may experience restlessness, panic, and even a sense of impending doom. Clinically, there sometimes appears the so-called triad, which includes simultaneous occurrence of difficulty breathing, chest pain, and hemoptysis, etc. Pulmonary embolism is primarily diagnosed clinically through pulmonary artery CT.
