Pulmonary embolism is usually hospitalized for about 2 weeks if vital signs are stable. However, if the condition is severe, with a drop in blood pressure and difficulty in breathing, hospitalization may be required for 1 month or more. Pulmonary embolism can be categorized into thromboembolism, air embolism, amniotic fluid embolism, etc. The duration of hospitalization varies according to the cause and severity of the disease. 1.2 weeks or so: Fatty embolism is usually caused by fat tissue in the bone marrow entering the pulmonary artery with the blood circulation after a long bone fracture; air embolism is mostly caused by a large amount of gas entering the blood vessels due to fast entry of the body into a place with low air pressure when diving or traveling by airplane. Generally these two cases are milder and the damage is more easily reversible, usually hospitalized for about two weeks. 2. 1 month and above: pulmonary thromboembolism may lead to patients with respiratory distress, heart failure, blood pressure drop and other clinical manifestations, and even life-threatening, requiring thrombolysis, surgery and other treatments, hospitalization time of about 1 month. Most of the amniotic fluid embolism is in critical condition, which can cause systemic organ failure and death in severe cases, and the hospitalization time is relatively prolonged, requiring more than 1 month. Therefore, the hospitalization time of pulmonary embolism is related to the cause of the disease and the severity of the disease. If you find symptoms such as chest pain, hemoptysis, dyspnea, etc., you should go to the regular hospital in time for timely treatment so as not to miss the best time for treatment, which may endanger your life.
