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.

Pulmonary embolism belongs to which department?

Pulmonary embolism mainly refers to the detachment of thrombi in the blood, leading to the obstruction of the main trunk of the pulmonary artery and its branches, causing a series of syndromes. Pulmonary embolism is an emergency in clinical practice. If the patient's circulation becomes unstable after the embolism, thrombolytic therapy should be considered. If the patient's respiratory circulation remains stable after the embolism, anticoagulation therapy can be considered. In clinical practice, pulmonary embolism is primarily diagnosed through pulmonary artery CTA examination to further clarify the diagnosis, and patients generally consult the respiratory medicine department.

Is there a relationship between pulmonary embolism and lung cancer?

Pulmonary embolism and lung cancer can be related; common causes of pulmonary embolism include amniotic fluid embolism, air embolism, and deep vein thrombosis. In patients with lung cancer, when cancerous emboli enter the bloodstream, they can cause pulmonary embolism. Additionally, if the patient's condition is poor, with difficulties in eating, prolonged bed rest, and increased blood viscosity, deep vein thrombosis can occur, leading to pulmonary embolism. Therefore, there is no absolute relationship between pulmonary embolism and lung cancer, but lung cancer may trigger 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 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.

How long does the treatment for pulmonary embolism take?

The timing of pulmonary embolism treatment mainly depends on the severity of the pulmonary embolism. The main goals of pulmonary embolism treatment are to save lives by addressing life-threatening right heart dysfunction and obstructive shock caused by the pulmonary embolism, to re-establish pulmonary vascular patency, restore lung tissue perfusion, and prevent the recurrence of pulmonary embolism. Main treatment methods include: respiratory and circulatory support, anticoagulation, thrombolysis, interventional or surgical removal of blood clots, placement of inferior vena cava filters, etc. General management: Patients who are highly suspected or diagnosed with pulmonary embolism should be closely monitored, tracking changes in respiration, heart rate, blood pressure, venous pressure, electrocardiogram, and blood gases to prevent the dislodgement of clots again. Absolute bed rest is required, and care should be taken not to overly bend the lower limbs, maintain bowel regularity, and avoid straining. For patients experiencing anxiety and panic symptoms, reassurance should be provided, along with appropriate use of sedatives. If there is chest pain, analgesics may be administered. For symptoms like fever and cough, corresponding symptomatic treatments should be given. To prevent lung infections and treat phlebitis, antibiotics may be used. Additionally, support treatments for respiratory and circulatory functions, as well as anticoagulation therapy, should be provided.
