Pulmonary embolism is a relatively common acute disease in clinical practice. It usually occurs when blood clots from the veins in the legs or pelvis detach, travel through the bloodstream to the pulmonary arteries, and cause an embolism. The onset of this disease is often very sudden. Due to different triggers, the clinical symptoms vary. Typical symptoms of pulmonary embolism include difficulty breathing, chest pain, coughing up blood, and coughing. Coughs are often dry, and patients may also have a small amount of white sputum. Some patients might even experience wheezing and other clinical symptoms. Therefore, the occurrence of excessive sputum is rare in patients with pulmonary embolism.

Can pulmonary embolism lead to pneumonia?

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.

Why can't patients with pulmonary embolism get out of bed?

Pulmonary embolism is a relatively common clinical disease, with many and complex inducing factors. The most common cause of pulmonary embolism in patients is due primarily to thrombi dislodging from the veins of the lower limbs or the pelvic deep veins, traveling through the bloodstream to the pulmonary arteries, thus causing the disease. Therefore, bed rest is essential during the acute phase of pulmonary embolism. The purpose of bed rest is to prevent further embolisms, to avoid the dislodging of pelvic or lower limb deep vein thrombi, which could lead to the formation of new thrombi. Therefore, for patients with pulmonary embolism, it is crucial to provide timely treatments such as thrombolysis to control the clinical symptoms caused by the pulmonary embolism effectively.

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.

Why does pulmonary embolism cause cardiac arrest?

The mechanisms causing cardiac arrest due to acute pulmonary embolism mainly encompass several aspects. One is a large-scale acute extensive pulmonary embolism, which prevents the blood from being ejected from the right heart, potentially leading to acute right heart failure. At this time, the entire body's blood circulation will encounter issues. Another scenario is that following the pulmonary embolism, it causes severe hypoxia. This hypoxia can lead to oxygen deficiency in all organs of the body, including the heart. The coronary arteries that supply nutrients to the heart can also become ischemic. Both of these factors can cause the heartbeat to lead to sudden cardiac arrest. These are the primary mechanisms that can cause a sudden stop in the heartbeat.

Is it good to place a filter for pulmonary embolism or not?

Whether it is good or not to place a filter for pulmonary embolism mainly depends on the cause of the pulmonary embolism and whether there are indications for placing a filter. Generally speaking, if pulmonary embolism is caused by the formation of blood clots in the lower limbs or the inferior vena cava, placing a filter can generally be beneficial. However, not all cases of lower limb venous thrombosis require a filter. Filters are usually only used for deep or large vein thromboses that are not suitable for thrombectomy or thrombolysis treatments. If a filter is placed under other conditions, it is very likely that thrombosis will re-form on the surface of the filter, potentially leading to some recurrent pulmonary embolisms or iatrogenic pulmonary embolisms. Therefore, the decision to place a filter is complex and requires a doctor to weigh the pros and cons before deciding whether or not to proceed.
