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 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.

Can I eat lamb if I have pulmonary embolism?

Patients with pulmonary embolism can appropriately eat mutton, as it is acceptable in their case. For pulmonary embolism, it is advocated to follow a light diet, avoiding spicy, irritating food, and excessively greasy food to prevent aggravating the gastrointestinal burden of the patient. Additionally, it is acceptable for patients with pulmonary embolism to consume some meat, as long as it is not fatty meat. Once diagnosed with pulmonary embolism, patients should receive active treatment, which often requires anticoagulant therapy. If the condition is not too severe, simple anticoagulant treatment may allow the patient’s condition to recover. However, if the pulmonary embolism is more severe, thrombolytic therapy may be necessary. After thrombolytic treatment, vascular anticoagulant therapy is given to manage the patient's condition.

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.

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.

Why do patients with pulmonary embolism feel sleepy?

Patients with pulmonary embolism primarily suffer from emboli within the venous system, which travel back to the right heart and then become lodged in the pulmonary artery, forming a pulmonary artery thrombus. This reduces pulmonary blood flow and impacts the exchange of air in the lungs, leading to hypoxia in the patient. Following hypoxia, the brain tends to enter a sleepy state, thus many patients with pulmonary embolism exhibit sleepiness. This sleepiness is related to the pathophysiological mechanisms of pulmonary embolism. At this point, it is crucial to provide sufficient oxygen to the patient to address their hypoxemia. Ultimately, the most fundamental treatments are prompt thrombolysis or anticoagulation therapy to resolve the embolus, addressing the condition fundamentally.
