Pulmonary embolism itself does not cause pneumonia; however, during the treatment of pulmonary embolism, procedures such as oral tracheal intubation and the creation of an artificial airway might be employed. These can lead to nosocomial infections of iatrogenic origin, resulting in pneumonia.

Pulmonary embolism often manifests as unexplained respiratory difficulty, pleuritic pain, tachycardia, and decreased oxygen saturation. Other high-risk factors include being over the age of 40, having a history of DVT (Deep Vein Thrombosis), obesity, prolonged immobilization, stroke, congestive heart failure, malignancy, lower limb fracture, anesthesia time exceeding 30 minutes during surgery, pregnancy and childbirth, use of estrogen, and a hypercoagulable state. These are all potential high-risk factors for pulmonary embolism.

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.

Can a pulmonary embolism be detected by a CT scan?

CT can detect acute pulmonary embolism, using CT angiography, which is the preferred imaging method for diagnosing pulmonary embolisms. It mainly shows central filling defects, as well as eccentric and abdominal wall filling defects, and complete filling defects. A diagnosis of pulmonary embolism can be made through the visualization of these filling defects on a CT scan. Additionally, some indirect signs, such as pulmonary hypertension, right ventricular enlargement, and the common mosaic sign, can also be observed. These are characteristic CT manifestations of acute 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.

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.
