Patient's question:
What tests are needed to confirm a diagnosis of pulmonary embolism?Doctor's answer:
Pulmonary embolism mainly causes symptoms such as chest tightness, chest pain, and low oxygen saturation. It is most commonly seen in patients with atrial fibrillation, the elderly, those who have been bedridden for a long time, and postoperative patients. Diagnosis is generally confirmed through careful examinations such as chest CT, pulmonary consolidation, D-dimer, and arterial blood gas analysis. Early treatment can involve the use of ventilators in combination with chemotherapy, thrombolysis, and anticoagulant medications. However, treatment for large-scale pulmonary embolism is often less effective.
