Pulmonary embolism


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.


Pulmonary embolism means
The formation of thrombotic foreign bodies in the human venous system or the right atrium and ventricle system, ultimately leading to the blockage in the pulmonary artery, is referred to as pulmonary embolism. After the onset of pulmonary embolism, patients may experience symptoms such as shortness of breath, chest pain, coughing, and even coughing up blood. It is crucial to immediately conduct a pulmonary artery CTA scan for further diagnosis. If the diagnosis of pulmonary embolism is confirmed, thrombolytic or interventional treatments can be considered.


Pulmonary embolism is caused by what?
The most common cause of pulmonary embolism is a thrombus, with approximately 70%-95% of cases occurring when a deep vein thrombosis dislodges and enters the pulmonary arteries and their branches via the bloodstream, leading to pulmonary embolism. Conditions such as prolonged bed rest or immobilization of the lower limbs can lead to the occurrence of deep vein thrombosis. Therefore, the primary site of origin is mainly the deep veins of the lower limbs. Additionally, other types of emboli can also cause pulmonary embolism, such as fat emboli, air emboli, amniotic fluid emboli, parasitic emboli, and bacterial emboli, as well as detachment of cardiac tumors; all these can lead to pulmonary embolism.


Is there a lot of phlegm in pulmonary embolism?
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.


Is pulmonary embolism related to pneumonia?
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.


Pulmonary embolism should be treated in the department of respiratory medicine.
Pulmonary embolism is an emergency in clinical settings, with rapid progression and extreme danger, and is generally treated by the department of respiratory medicine. Pulmonary embolism primarily occurs due to dislodged blood clots that block the pulmonary artery and its branches, leading to pulmonary infarction. The clinical manifestations of pulmonary embolism mainly include severe breathing difficulties, chest pain, coughing up blood, and even circulatory disturbances. After a pulmonary embolism occurs, a pulmonary artery CT scan can be used to further confirm the diagnosis. Treatment options may include thrombolysis, and possibly anticoagulation therapy with low molecular weight heparin or warfarin. (Specific medications should be used under the guidance of a physician.)


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.


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 pulmonary embolism result in a vegetative state?
After a pulmonary embolism, if it is an acute and extensive embolism and not treated promptly, it can lead to severe hypoxemia. If hypoxemia is not addressed quickly and persists, it will affect the oxygen supply to vital organs throughout the body, including the brain. The brain is the organ most vulnerable to oxygen deprivation. If there is complete lack of oxygen for just four minutes, irreversible damage occurs to the cerebral cortex, and the patient will not wake up, leading to a vegetative state. Therefore, in cases of acute extensive pulmonary embolism, if treatment is delayed, there is a significant risk of the patient entering a vegetative state, and the mortality rate is also very high. Many patients may experience sudden death.
