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.

The most common symptoms of pulmonary embolism.

Pulmonary embolism is also relatively common in clinical practice, primarily caused by an embolus blocking the pulmonary artery system, leading to a group of clinical syndromes. The clinical manifestations of pulmonary embolism mainly include the following points: The first is that patients may experience unexplained difficulty breathing and shortness of breath, especially after activity. The second is that patients experience significant chest pain. The third may be accompanied by hemoptysis, but usually, the amount of blood expectorated is not large. The fourth is that patients may experience restlessness, panic, and even a sense of impending doom. Clinically, there sometimes appears the so-called triad, which includes simultaneous occurrence of difficulty breathing, chest pain, and hemoptysis, etc. Pulmonary embolism is primarily diagnosed clinically through pulmonary artery CT.

Will acute pulmonary embolism get better in two days?

Acute pulmonary embolism is a type of disease with very many and complex inducing factors. Clinically, acute pulmonary embolism has a very sudden onset, and patients often present with unexplained symptoms such as pale complexion, chest tightness, chest pain, and difficulty breathing. During the acute phase of pulmonary embolism, immediate and effective anti-shock and other symptomatic resuscitation are essential upon arrival at the hospital. Generally, after timely and effective resuscitation, the patient's condition may be somewhat controlled. Usually, the first 1-3 days after the onset of pulmonary embolism are the most dangerous; therefore, continuous monitoring of the patient's vital signs is crucial during this time, followed by anti-shock and anticoagulation treatment as needed. Therefore, acute pulmonary embolism will not improve by the second day, although some of the patient's clinical symptoms may slightly improve after treatment.

What are the precursors of pulmonary embolism?

Pulmonary embolism is also relatively common in clinical practice. Its precursors may include varying degrees of respiratory difficulty, chest tightness, and shortness of breath, among others. If such symptoms occur, medical attention should be sought promptly, primarily to rule out the possibility of acute myocardial infarction. Pulmonary artery CTA can further confirm whether there is a pulmonary embolism. In cases of extensive pulmonary embolism, there is a high risk of sudden death, and aggressive thrombolytic and anticoagulation treatments should be administered. If the patient's chest tightness and shortness of breath are relieved after the aforementioned treatments, hospitalization for observation and treatment is still necessary.

What are the symptoms when pulmonary embolism becomes severe?

Pulmonary embolism can vary in severity, with serious cases primarily causing unstable vital signs. The disease primarily arises from venous thrombi in the venous system, which travel with the venous blood back to the right heart, and then with the blood flow from the right heart back to the aorta. If the thrombus is relatively large, it can easily become lodged in the pulmonary artery, forming a pulmonary embolism. The symptoms of pulmonary embolism can range from mild to severe. Based on the patient's symptoms and vital signs, pulmonary embolism is categorized into low risk, intermediate risk, and high risk. Low and intermediate risk typically indicate that the patient's vital signs are relatively stable, with normal blood pressure, heart rate, and pulse oximetry saturation. In severe cases, patients may exhibit noticeable symptoms such as coughing up blood, difficulty breathing, low blood pressure, shock, and oliguria. These represent the more severe cases of 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.
